For a 6 or 8 pin connector version, Pin A is Sig+/Exc+ and pin B is Sig-/Exc-.For conduit output configurations, please look at Electrical Connections chapter.Assure proper loop feeding voltage is applied to transmitter.The measurement chain connected to the transmitter is calibrated as follows:1) Reset the offset on the instrument by eliminating the thermal drift with the Autozero function.With the sensor installed and the extruder at working temperature, wait until the temperature itself is stable, with a pos- sible variation of ± 1°C. Consequently Autozero can be activated.This allows to compensate all the signal drifts caused by tightening and temperature. Additional Autozero activations could be run once the temperature stability is reached, with ± 1°C of possible variation.2) Calibrate the instrument activating the CAL function.The transducer brings its output to the calibration value shown on the transducer data plate (80% of full scale default, if changed with HART command it could be different). With the external Autozero function the calibration procedure is not feasible.3) If the instrument does not exactly indicate zero, repeat points 1) and 2).READY-TO-USE Using HART CommunicatorBring the system to the working temperature with the transmitter installed and connected to the measurement instrument without any pressure applied.1) Connect Communicator to the loop. In case it’s not sure on how to do this, please refer to “Connecting the HART Handheld Communicator” (Figure 8.1).2) Switch on HART Communicator. For reference please refer to HART Command tree on the following page.3) From the main menu:a. Enter Tag (Fast Key 1, 3, 1)b. Set Pressure Units (Fast Key 1, 3, 3), if neededc.

They read media pressure up to a temperature of 538°C, and resist such high temperatures thanks to their special mechanical construction, in which the measurement element is isolated from the Melt.The constructive principle is based on hydraulic transmission of pressure; mechanical strain is transferred by means of a non-compressible transmission liquid.The liquid used in these sensors may be mercury (i.e. HM series), FDA-approved oil (i.e. HW series) or NaK (i.e. HK series). Strain gauge technology translates the physical quantity (pressure) into an electrical signal. Four different designs are available: rigid rod, flexible sheathing, flexible plus thermocouple, and exposed tip. Gefran Melt sensors satisfy all installation and field requirements.The sensors can read an extremely wide range of pressures: from a version with minimum range of 0-17 bar up to a version with a scale of 0-2000 bar.All models in the catalog can be supplied in two different classes of accuracy*: class M, with accuracy of 0.5% FS, and class H, with accuracy of 0.25% FS. Ex and Performance Level ‘d’ or SIL2 certified versions are available.* For HMX/HWX products sold to EAC Customs Union (EAC mark), due to a different method of calculation, the limits of accuracy are the following:_M = 1%_H = 0,5%For all the other details and technical features please keep as reference the product datasheets or Gefran website .4.1 HWE – Technical dataAccuracy (1) H <±0.25%FS (100...1000 bar)M <±0.5%FS (17...1000 bar) Resolution16 bitMeasurement range0..17 to ... 0..1000bar0..250 to 0..15000psi Rangeability3:1Maximum overpressure (without degrading performances) 2 x FS1.5 x FS above 500bar/7500psi Measurement principle ExtensimetricPower supply13...30VdcMaximum current absorption23mA (40mA with relay optional) Output signal Full Scale (FS)20mAZero balance (tollerance ± 0.25% FS)4mACalibration signal80% FSPower supply polarity reverse protection YesCompensed temperature range housing0...+85°COperating temperature range housing-30...+85°CStorage temperature range housing-40...+125°CThermal drift in compesated range: Zero / Calibration / Sensibility< 0.02% FS/°C Diaphragm maximum temperature315°C / 600°FZero drift due to change in process temperature (zero)< 0.04 bar/°CStandard material in contact with process medium Diaphragm:• 17-7 PH corrugated diaphragm with GTP+ coating Stem:• 17-4 PHThermocouple (model HWE2)STD: type “J” (isolated junction) Protection degree (with 6-pole female connector)IP65Electomagnetic compatibility – Emissions EN 61326-1 EN 61326-2-3 EN 61326-3-1Electomagnetic compatibility – Immunity EN 61326-1 EN 61326-2-3 EN 61326-3-1FS = Full scale output(1) BFSL method (Best Fit Straight Line): includes combined effects of Non-Linearity, Hysteresis and Repeatability.For products sold to EAC Customs Union (EAC mark), due to a different method of calculation, the limits of accuracy are the following: _M = +-1%_H = +-0,5%4.2 -

Extrusion pressure can be checked by means of espe-cially designed transducers. Thanks to their special mechanical construction, in which the measurement ele-ment is isolated from the Melt, they resist to such high temperatures. The constructive principle is based on hydraulic of pressure; mechanical strain is transferred by means of a non-compressible transmission liquid. Strain gauge technology translates the physical quantity (pressure) into an electrical signal.Following advice for extending the sensors lifetime.a) Avoid shocks and abrasions to the in contact diaphragm. Protect the transducer with its cover each time you remove it from its seat.b) The seat must be prepared perfectly and with appropriate tools in order to respect the depth and axiality of the holes and tapping.Pay particular attention to the coaxiality of the holes to the thread, because diaxialities greater than 0.2 mm will break the transducer during assembly. It is essential that hole depth guarantees the absence of chambers or air pockets in which extrusion material may be trapped.To prevent contact with the extrusion screw or with tools used to clean the extrusion chamber, the front diaphragm must not extend from the inner wall of the extruder.c) Before assembling the transducer in machines already in operation, make sure that the housing is clean. Remove any residual with the suitable cleaning device.d) The transducer should be removed only with the machine empty (without pressure) but still hot.e) The transducer should be cleaned with solvents for the material being processed.Any mechanical action on the contact diaphragm modifies its operation and could break it.6.1 - Installation seatThe installation seat has to be realized:Drilling kitA drilling kit with formed tools for drilling, reaming and tapping is available to facilitate correct preparation of the assembly seat. The assembly seat must be perfect to assure proper transducer function and long lifetime. Drilling kits are available in the following versions: KF12, KF18.Drilling procedure1) To drill hole (D4) up to a distance from the hole equal to the sum of (A+B+C) (tool 3).2) Make the pass through hole (D2) by the tool 1.3) To create the seal seat at a distance from the hole equal to dimension (A) (tool 4).4) With a roughing tap, create threading 1/2-20UNF-2B (recognizable from the greater number of threads beveled at the mouth) (tool 5).5) With a finishing tap, go over threading 1/2-20UNF-2B up to a distance from the bottom equal to the sum of (A+B) (tool 6).6) To ream the hole (D2) with reamer (tool 2).Installation seat checkThe dimensions of the assembly seat have to be checked after preparation and before the transducer installation.Use dummy plug SC 12/18 as follows:1) Coat the end of the rod with the appropriate ink.2) Lubricate the threaded part to prevent friction.3) Insert the dummy plug and screw it fully down.4) Remove the rod and examine it.With the exception of 45° surfaces, the ink should be intact on the entire surface .6�2 DRILLING TOOL KITCORRECT INSTALLATIONWRONGWRONGWRONGCORRECTVERSION CODE KF12KF18THREADING TYPE 1/2-20UNF-2BM18x1.51Ø 7.6Ø 9.752Ø 7.95Ø 10.13Ø 13Ø 204Ø 11.5 with pilot guideØ 16 with pilot guide51/2-20UNF-2Broughing M18x1.5roughing61/2-20UNF-2Bfinishing M18x1.5finishingIncorrect working or shape of the side can result in properties out of specification, bad behaviour or damage to the sensor.The side should be clean and without any polymer residual.contact surfaceTRANSDUCER INSTALLATIONInstallation procedure1) Make sure the drilling procedure has been realized correctly. If the sensor is installed in a previously used hole, make sure the hole is completely clean and free of any plastic residual.2) Remove the protective cap from the sensor tip.3) Lubrificate the thread with non-grip grease such as Neverseez (Bostik), or C5A (Felpro), or equivalent.4) Insert firmly the sensor into the hole, first by hand and then with a wrench, 1/4 turn at a time.Recommended torque: 50 Nm, the maximum is 56.5 Nm.Removal (Figure 1)To remove the transducer from its seat and carry on the working process, dummy plugs with identical mecha-nical dimensions are available.The dummy plugs differ by type of threading; max pressure range is 2000 bar for all rods.The dummy plugs are available in the following versions: SC12 1/2-20UNF seat - SC18 M18x1,5 seat.Brackets (Figure 2)Models with flexible sheaths require the housing precise fixing. Suitable fastening brackets (SF18) are recom-mended.Remember that the fastening point must be vibration-free (vibrations affect the measurement) and that tem-peratures must not exceed the maximum temperature range for the strain gauge housing (as stated on the sensor technical sheet).Extruder startingBring the system to working temperature with the transducer installed and without any pressure applied. Wait until all the material is at the same temperature to prevent the transducer damage by semi-solid material.Seat cleaning & Cleaning toolAs mentioned in the notes, the seat must be cleaned before the transducer installation.The cleaning tool is a hard metal cutting tool specially designed to remove working materials residuals.Recommended procedure (Figure 3)The following procedure must be implemented with the material in a fluid condition.1) Insert the tool in the seat and screw down the cutting rod (normally a 1/4 turn at a time).2) Turn the pilot cutter clockwise until there is no resistance to cutting.3) Repeat the procedure until the seat is completely clean.For constructive reasons, the maximum torque applicable to the cutter is 15 Nm (1.5 Kgm).If the hole occlusion requires higher torque for removal, use the drilling kit and follow the recommended procedure.The cleaning tool is available in the following versions: CT12 1/2-20UNF seat - CT18 M18x1,5 seat.Figure 1Figure 3Figure 26�3 - Wiring and calibrationConnectionsThe sensors have to be connected as shown in the diagram at chapter 7.To obtain a higher immunity from field noise, connect the cable shield to the female connector case on sen-sor side.Calibration procedure using the magnetic pen/Pin CALBring the system to the working temperature with the transmitter installed and connected to the measure-ment instrument without any pressure applied.The measurement chain connected to the transmitter is calibrated as follows:1) To reset the offset on the instrument by eliminating the thermal drift with the autozero function.With the sensor installed and the extruder at working temperature, wait until the temperature itself is stable, with a possible variation of ± 1°C. Consequently Autozero can be activated. This allows to compensate all the signal drifts caused by tightening and temperature.Additional Autozero activations could be run once the temperature stability is reached, with ± 1°C of possible variation.2) Calibrate the instrument activating the CAL function. The transducer brings its output to the calibration value shown on the transducer data plate (80% of full scale default, if changed with HART command it could be different).With the external Autozero function the calibration procedure is not feasible.3) If the instrument does not exactly indicate zero, repeat points 1) and 2).In this way, the instrument is calibrated to give the exact indication in the chosen engineering unit.Calibration procedure using HART communicationBring the system to the working temperature with the transmitter installed and connected to the measure-ment instrument without any pressure applied.1) Connect Communicator to the loop. In case it’s not sure on how to do this, please refer to “Connecting the HART Handheld Communicator” (Fig. 8.1).2) Switch on HART Communicator. Please refer to HART Command tree on Ready-to-Use guide.3) From the Main Menu:a. Enter Tag (Fast Key 1, 3, 1)b. Set Pressure Units (Fast Key 1, 3, 3), if neededc.

Heater is to be connected and serviced only by qualified personnel experienced in electrical, and pipingwork.2. Installation and wiring of the heater must adhere to all applicable codes.3. For use with non-lethal fluids only, see ASME Section VIII, Div 1, UW-2.4. Heater is suitable for maximum operating pressure of 450 psi (3103 kPa) and maximum operatingtemperature of 550°F (288°C). Refer to heater and heat-exchanger data plate.5. Heater is suitable for use in hazardous locations only if fitted with an approved electric motor and the heatexchanger fluid temperature is below the ignition temperature of the atmosphere. Ensure installation and service work is performed by a qualified electrician experienced with hazardous location equipment.6. Do not operate heater in atmospheres which are corrosive to aluminum or steel, unless it has been coatedwith a factory approved protective coating.7. Heater must be kept clean. When operating in a dirty environment, regularly clean the fin tubes, fan, and fanguard. Refer to recommended maintenance procedures.8. Use factory approved replacement parts only.— INSTALLATION —These instructions are to be used as a general guideline only.LocationPlease follow guidelines below for optimum heating results:1. Do not install heaters such that airflow is blocked or impeded by equipment or walls.2. For occupant comfort, position heaters so that air discharge is directed across areas of highest heat loss,such as doors, windows, and outside walls.3. For large areas, arrange heaters such that the air discharge of one heater is directed towards the inlet of thenext heater. This sets up a rotational airflow with air circulation in the central area of the building.4. For equipment freeze protection, direct air discharge at required equipment.5. For large workshops or warehouses it may be acceptable to use fewer, but larger heaters.6. Do not direct air discharge towards a room thermostat.Mounting1. A variety of mounting brackets are available from the factory to aid in installation.2. The heater is designed to be installed in an upright and level position. While it may be installed in otherpositions, for steam service, the inlet must be above the outlet and the bottom of the heat exchanger must drain towards the outlet.3. Heaters are designed to be mounted from the top or bottom of cabinet using two 1/2 in. (12 mm) bolts orthreaded rod/pipe (rod or pipe can be extended through both top and bottom panels for extra support).4. It is essential that adequate structural support be provided for installation. The mounting structure must bestrong enough to support the heaters weight, provide sufficient stiffness to prevent excessive vibration, and withstand all probable abusive situations such as transportable installations where truck off-loading impacts, etc. may occur.Mounting Heights and Clearances1. To ensure that warm air reaches the floor, heaters are usually mounted 7-1/2 ft. (2.3m) to 12 ft. (3.6 m)above the floor. Heaters may be mounted at higher elevations and still provide warm air at floor level however, the maximum mounting elevation at which this occurs depends on location and operational conditions.2. Louvers may be adjusted to provide greater downward deflection of the discharge air. However, it isrecommended that louvers not be set less than 15 degrees from the closed position.3. Leave at least 22 in. (559 mm) clearance between the rear of the motor and the nearest obstruction.— Piping Practices —1. Steam unit heaters condense steam rapidly, especially during warm-up periods. The return piping must beplanned to keep the heat-exchanger’s core free of condensate during periods of maximum heat output, and steam piping must be able to carry a full supply of steam to the unit heater to take the place of condensed steam. Adequate pipe size is especially important when a unit heater fan is operated under on-off control because the condensate rate fluctuates rapidly.2. Heater is to be connected and serviced only by qualified personnel experienced in piping work. For addi-tional piping information refer to industrial piping handbooks and related literature.3. Eliminate pipe stress by adequately supporting all piping. Do not rely on heater to support piping.4. Take off all branch lines from the top of steam mains, preferably at a 45° angle, although vertical 90°connections are acceptable.5. Pipe the branch supply line into the steam unit heater’s inlet at the top and the return branch line from theoutlet at the bottom.6. In steam systems, the branch from the supply main to the heater must pitch down towards the main and beconnected to its top in order to prevent condensate in the main from draining through the heater, where it might reduce capacity and cause noise. In long branch lines, a drip trap may be needed.7. Allow for pipe expansion to prevent excessive strain on the unit heater’s heat-exchanger core.8. The return piping from steam unit heaters should provide a minimum drop of 10 in (254 mm) below theheater so that the pressure of water required to overcome resistances of check valves, traps, and strainers will not cause condensate to remain in the heater.9. In steam systems, where horizontal piping must be reduced in size, use eccentric reducers that permit thecontinuance of uniform pitch along the bottom of piping (in downward pitched systems). Avoid using concentric reducers on horizontal piping, because they can cause water hammer.10. Installing dirt pockets at the outlet of unit heaters and strainers with 0.063 in. (2 mm) perforations to preventrapid plugging are essential to trap dirt and scale that might affect the operation of check valves and traps.Strainers should always be installed in the steam supply line if the heater is valve controlled.11. In steam or hot water systems, rapid air removal is required because entrained air is a cause of corrosion.Hot water systems should be equipped with suitable air vent valves for rapid and complete air removal at high points, at the top of each unit heater, and ends of both supply and return mains. Proper air venting for steam systems can be achieved by use of a steam trap with an internal air vent.12. Steam traps must be located below the outlet of the unit heater. Consult the trap manufacturer for specificrecommendations. Each steam unit heater should be provided with a trap of sufficient size and capacity to pass a minimum of twice the normal amount of condensation released by the unit at the minimum differen-tial pressure in the system. Trap capacity is based on the pressure differential between supply and return mains. Steam systems should be equipped with a float and thermostatic trap or inverted bucket trap with an air bypass.13. If the condensate return line is above the heater outlet or is pressurized, install a check valve after thesteam trap and a drain valve at the strainer to drain the system during the off season.14. Install pipe unions and shut-off valves at connection points of each unit heater to allow maintenance orreplacement of unit without shutting down and draining the entire system. For hot water systems include a balancing valve in return line for flow regulation. A drain valve should be provided below each unit heater to allow removal of water from the heat-exchanger core if located in an area subject to freezing.15. Adequate air venting is required for low-pressure closed gravity systems. The vertical pipe connection tothe air vent should be at least 3/4 in. NPT to allow water to separate from the air passing to the vent. If ther-mostatic instead of float-and-thermostatic traps are used in vacuum systems, a cooling leg must be installed ahead of the trap.16. In high-pressure systems, it is customary to continuously vent the air through a petcock unless the steamtrap has a provision for venting air. Most high-pressure return mains terminate in flash tanks that are vent-ed to the atmosphere. When possible, pressure reducing valves should be installed to permit operation of the heaters at low pressure. Steam traps must be suitable for the operating pressure encountered.17. On steam systems where the steam supply to the unit heater is modulated or controlled by a motorizedvalve, a vacuum breaker should be installed between the unit outlet and a float and thermostatic trap.Heat-Exchanger Core Assembly Replacement1. Remove heater from its mounting location and lower to floor or stable working surface. Assistance is usually required to remove heater safely.2. Remove louver blades from front of cabinet using a 5/16 in. wrench or socket.3. Remove four 1/4 in. bolts holding left-side cabinet panel (when facing heater front) to top & bottom panels.4. While supporting the weight of the heat-exchanger core, by the left piping connection, remove the two 1/4 in. core bolts from left and right-side cabinet panels. Allow heat-exchanger core to rest on bottom of cabinet.5. Remove the left-side fan guard and left-side cabinet panel as follows (if heater has optional flanged connections, also remove top cabinet panel): (a) While supporting the motor mount, remove the two 5/16 in. bolts holding the motor mount to the left side of the cabinet and fan panel assembly. (b) Remove left-side cabinet panel and then reinsert the 5/16 in. bolts into the fan panel assembly. Place a support under the motor mount to prevent cabinet from tipping backwards towards motor during removal of heat-exchanger core.6. With the left-side cabinet panel removed and motor mount supported, slide heat-exchanger core out of cabinet.7. To install heat-exchanger core into cabinet, reverse order of above procedure and tighten fasteners to proper torque setting.Fan, Fan Guard or Motor Replacement1. For replacement of fan or fan guard remove four bolts holding motor to the motor mount. For HHP2-30 alsoremove speed reducer bolts. If replacing motor only on HHP2-30, only remove motor mounting bolts and C-face flange bolts. 2. Detach two-piece fan guard assembly by removing top and bottom screws that attach the fan guard to thecabinet. 3. Remove fan guard pieces through top or bottom. Due to stiffness of fan guards, you may need to removetwo outer top or bottom bolts that attach the fan panel to the top or bottom cabinet panels to provide suffi-cient clearance. 4. Lift the motor, speed reducer (for HHP2-30 only) and fan assembly off the motor mount. 5. Loosen fan hub screws and remove fan blade from motor shaft.6. To reassemble, position fan on motor shaft with end of shaft even with face of hub. Ensure the set screw isfaced towards motor and lined up perpendicular to factory-ground flat on motor shaft. This flat is our “Easy-Off” fan blade replacement feature and only comes on motors purchased from Hazloc Heaters. Tighten set screw to 150 in-lbs torque. 7. Place motor, speed reducer (for HHP2-30 only) and fan assembly onto motor mount and fasten the two-piece fan guards to the cabinet. 8. Center fan in fan-shroud opening and leave approximately 1/16” to 3/16” (1.6 to 4.8 mm) gap betweenmotor face and fan guard. 9. Bolt motor to motor mount, tighten nuts to 250 in-lbs torque. Manually spin the fan blade to ensure it rotatesfreely before reconnecting heater to power supply. Fan must rotate counterclockwise when viewed from rear of heater.— Repair and Replacement —Torque SettingsItem Torque (in-lbs)Fan blade set screw 150 5/16 - 18 UNC motor nuts 250 5/16 - 18 UNC motor mount bolts 250 1/4 - 20 UNC fan panel bolts100 1/4 - 20 UNC fan guard self tapping screws 100 #10 - 24 UNC louver blade screws28DescriptionHHP2-30Part NumberCore assembly Due to the many variations in core configurations and sizes, fluid connection types, and coat-ings, please contact factory with heater model and serial number.Top/Bottom panel HHP2-30-20-001 Side panel HHP2-30-20-002 Fan panel HUH1-30-22 Motor baseHHP2-30-20-007 Left side motor bracket HUH2-36-20-006 Right side motor bracket HUH2-36-20-005 Fan blade HHP2-30-FBMotor (56C frame)Specify motor voltage, phase, frequency, horsepower & type of enclosure (totally enclosed or explosion-proof)Speed Reducer HUH2-36-SD Speed Reducer Shim HUH2-36-20-010 Fan guard (2 pieces) HUH1-30-20-008 Louver blade kitHHP2-30-20-003-KTop/Bottom panel screw kit HHP-TB-SK Side motor bracket screw kit HUH2-36-MB-SKMotor bolt kit HH-MB-SKCore screw kit HHP-CM-SKMotor base bolt kit HH-MM-SK Speed reducer screw kit HUH2-36-GB-SKFan guard screw kit HH-FG-SK Louver screw kitHHP2-30-LB-SK*** Please have model & serial number of heater available before calling ***HHP2 (30 inch model)— Maintenance Program —Regular inspection, based on a schedule determined by the amount of dirt in the atmosphere, assures maximum operating economy and heating capacity.Annual Inspection (before each heating season)1. Check all terminal connections and electrical conductors for damage, looseness, defects, fraying, etc. andreplace or tighten where applicable.2. Check for fluid leakage from heat-exchanger core. If fluid leakage occurs, remove heater from service andhave the heat-exchanger core replaced by a factory replacement unit. Refer to “Repair and Replacement”section for complete details. Note: This heat-exchanger core is covered by the Safety Codes Act and therefore is not field repairable.3. Check electrical junction box. Inside of enclosure must be clean, dry, and free from any foreign materials.The cover must also be completely on and tight.4. Check motor shaft bearing play. Replace motor if play is excessive or if motor does not run quietly andsmoothly. Motor bearings are permanently lubricated.5. On HHP2-30 models, speed reducer is maintenance free . Check for excessive noise and vibration.6. Check fan. Replace immediately if cracked or damaged.7. Check louvers. Louver screws should be tight. Louvers are not to be set less than 15 degrees of the closedposition.8. Check the tightness of all hardware. All nuts and bolts, including mounting hardware, must be tightened totorque settings on Page 9.9. Turn heater motor on for a minimum of 10 minutes.

They block one or both hydraulic consumer lines or are used as a hydraulically actuated drain or circulation valve.In the closed state the check valve type DRH has zero leakage. It is a twin check valve for double-acting consumers. Available with hydraulic release. Hydraulic release suppresses relief surges that can occur at high pressure and with a large consumer volume.Features and bene ts:■Pressures up to 500 bar■with hydraulic release for smooth switchingIntended applications:■Blocking of leak-free hydraulic cylindersVersions:■Pipe connection■Manifold mountingReleasable twin check valve type DRHCheck valves■Used in all customary applications in which a consumer is controlled via a directional spool valve with a blocked or free pump through- ow or when several consumers are selectively actuated via directional spool valves in a parallel circuit. See Chapter 6, "Circuit examples". To release the pressure blocked at A or B, approximately 0.4 times the pressure is required on the other side.Versions with integrated pressure-limiting valves enable use in conjunction with hydraulic motors, pivoting or rotating cylinders (type DRHS or DRHCS with shock valves), or with miniature pressure-limiting valves make it possible to avoid slow pressure build-upse.g. by expansion of volume with a rise in temperature (type DRH..SS).Check valves with drain port■For all applications where several consumers are actuated in series with the P d R pump through- ow. If a downstream direction-al spool valve is actuated, all upstream spool valves are loaded with the system pressure of the actuated consumer in the P d R through- ow, so that leakage oil slowly penetrates into the consumer connections and lines (see Chapter 6, "Circuit examples").The continuous drainage of leakage oil via the separate leakage line prevents a gradual pressurisation with uncontrolled release and possible drifting of the consumers. The leakage outlet is closed when the check valve is in the released position.Check valves with hydraulic release■For applications where the basic version cannot be released due to unfavourable area or load ratios at the hydraulic cylinder (rod side). Relieving the hydraulic release takes approx. 0.1 times the pressure on the opposing side. The hydraulic release can be single-sided (type DRH..V) or on both sides (type DRH.. VV).2Available versions, main dataCircuit symbol:DRH 1DRH 2DRH 3DRH 3 L DRH 4 LDRH 5 LDRH 1 PDRH 3 PDRH 3 PG...DRH 3 LSS-..DRHS 2..DRH 3 SS-..DRHCS 2DRH 2 ADRH 2 MAOrder coding example:Shock valve pressure setting (bar); see Chapter 3, "Parameters"Table 1 Basic type, size, functionTable 1 Basic type, size, function3Parameters General informationCharacteristic curvesOil viscosity approx. 50 mm 2/sCurve 1:C d AD d BCurve 2: A d C B d D(released)Δp ow resistance (bar); Q ow rate (lpm)Δp ow resistance (bar); Q ow rate (lpm)Pilot pressure p St (bar) on the feed side (reference value)To release:p St, 0.4 p A(B) + 3p A(B)Pressure (bar) on the blocked side Aor BHydraulic release for release:p StV, 0.1 p A(B) + 12To keep open: 1p St , 0.5 Δp A(B) + p C(D) + kΔp A(B)Flow resistance curve 2 at released port A or Bp C(D)Pressure (bar) on the out ow side C or Dk, 6 DRH 1 and DRH 2, 4 DRH 3, 3 DRH 4 and DRH 5WeightType DRH 1= approx. 0.5 kg DRH 2= approx. 1.2 kg DRHS 2= approx. 1.5 kg DRHCS 2= approx. 1.8 kg DRH 3= approx. 1.6 kg DRH 4= approx. 2.9 kg DRH 5= approx. 5.5 kg1A (dragging) load in the direction of the consumer movement may cause utter at the check valve.

本产品系国家“七五”重点科技攻关项目和电力部“八五”重点
推广项目。
先后在葛州坝50kV开关站，武汉凤凰山500kV变电站，沈阳变压器厂等对数百台变压器进行测试，工作可靠，操作方便。
二、系统原理：
HTJF-H系统采用的检测方法是世界上目前最广泛采用的直接法、电桥平衡法、电流脉冲法，其基本原理：试品产生一次局部放电时，试品Cx两端产生瞬时的电压变化ΔU，经过一耦合电容Ck耦合到检测阻抗Zm，回路中会产生一脉冲电流I，将此脉冲电流I经检测阻抗Zm产生的脉冲电压进行采样，放大和显示处理，就可以测定局部放电的视在放电量等参数。
脉冲电流法主要利用局部放电信号频谱中的较低频部分，可避免无线电干扰。
HTJF-H系统配置RLC型检测阻抗，他测量局部放电产生的脉冲信号，并抑制实验电源的工频及其它低频干扰信号。
