The Electrochemicalsensor is manufactured by Interscan. Electrochemical means thatit produces an electrical current proportional to the level of gaspassing through. The large size of the Interscan sensors results inlarger reactive surface area which yields greater sensitivity. Equipment Description(fig. 1)Designation FunctionLCD Display:Indicates gas level when function switch is inZERO, SAMPLE INACTIVE or SAMPLEACTIVE, and battery level when on BAT.TEST A or B.ALARM Light:LED. Flashes ON/OFF when alarm setpoint is exceeded.ALARM SET:25-Turn potentiometer with a screwdriveradjustment. Sets the alarm trip point at thedesired gas level. (low alarm set must begreater than 5% of the full scale).SPAN/CAL:25-Turn potentiometer with a screwdriveradjustment. Sets display to correspond to theconcentration of the calibration gas used forcalibrating the instrument or to the levelspecified on ECS certificate.FUNCTION SWITCH:Rotary switch as follows:OFF:Analyzer power is OFF.SAMPLEINACTIVE:Analyzer power is ON (pump is OFF),Sampling is inactive.SAMPLEACTIVE:Analyzer power and pump are on. Also in thisposition the analyzer is zeroed. Samplemeasurements and calibration areaccomplished in the sample mode.BAT.TEST A:Indicates state of charge of the Nickel-Cadmium (NiCd) batteries on the LCDDisplay. These batteries power the pump &alarm. Recharge if the LCD Display level fallsto or below 100 (ignore decimal point).BAT. TEST B:Indicates state of charge of the “C” sizealkaline batteries on the LCD Display. Thesebatteries power the main circuitry, display andare NOT re-chargeable. Replace if the LCDDisplay level falls to or below 100 (ignoredecimal point). You must allow an overnightstabilize prior to use if the batteries arereplaced. Batteries are to be checkedevery 30 days.ZERO:10-Turn Potentiometer. Allows the meter to beadjusted to zero, by compensating for anybackground signal.(fig. 2)Designation FunctionINLET:¼” O.D. Quick connect or compression gasfitting.OUTLET:¼” O.D. Quick connect or compression gasfitting.RECORDER OUTPUT:¼” phone jack for Analog recorder outputconnection. Typically 0-100mV. Tip –positive, Ring – ground.CHARGER INPUT: 3.5mm phone jack for 9V DC, 100mA chargerinput. Tip – positive, Ring – ground.SENSOR SCREWS:Used to hold Sensor or Sensor base in place.(fig. 3)AUDIBLE ALARM:Piezoelectric Horn, sounds when alarm setpoint is exceeded.The above (fig 3) page 7, #12 indicates two #1 Phillips-head screws located on the right side panel. Removing these screws allows access to the internal components. Do not remove any other screws(fig. 4)Operating InstructionsNormally, the alarm is set at the Factory at 50% of full scale. Thealarm can be reset to any desired level by following the procedurebelow. Minimum alarm level must be greater than 5% of the fullscale measuring range.Set FUNCTION switch to SAMPLE INACTIVE. Using the ZEROcontrol, advance the LCD display to the desired alarm set point.Some analyzers require the use of span tool (provided). Adjust theALARM SET (fig. 1 pg. 4)control until the alarm sounds. Adjust theZERO control slightly counterclockwise until the alarm is silent. Toconfirm setting slowly adjust the ZERO control clockwise until thealarm sounds. Re-adjust the ALARM SET control if necessary.Adjust the ZERO control for a reading of “0” on the display.The Analyzer must always be zeroed, prior to use.Zero adjustments must be made in the SAMPLE ACTIVE mode,i.e. with the pump on, in air free of interfering gases. If necessary,use zero air or a C-12 filter (provided) to zero in the sampling area.When using C-12 zero filter, connect externally to gas inlet. Allowreading to stabilize, before making final zero adjustment,(stabilization can take approximately 20 minutes). The C-12 filtermust be removed after zeroing the analyzer.Analyzer must be zeroed prior to sampling (section 2.1).Set the FUNCTION switch to SAMPLE ACTIVE to activate the pump. If the INLET or OUTLET is blocked, the pump may stall. Note: Running the Analyzer with blocked INLET or OUTLET may lead to the sensor leaking caustic electrolyte leading toanalyzer damage.Power analyzer off, and clear the blockage. To reset the pump, set the FUNCTION switch to SAMPLE INACTIVE momentarily and then switch again to SAMPLE ACTIVE.Nominal sample rate in MOST analyzers is approximately 1.0, ±0.2 liter per minute. NOTE: For hydrazine analyzers with the measuring range of 0-100ppb the sample flow rate is 2.2 ± 0.2 liters per minute.The Average sample run time, starting with fully charged “C” NiCd batteries, is 12 hours. If the BATTERY TEST “A” indication is down to 100 on the LCD display, the flow rate may have started to decrease. This is usually not a problem unless very precise readings are required.Sampling from high pressure may only be achieved by using the method indicated in (fig. 5).Note: The sample to the Interscan Analyzer must be drawn perpendicular to the Sample flow stream.(fig. 5)CalibrationAll analyzers are factory calibrated prior to shipment.There is no easy answer as to how often a monitor should becalibrated. This is strictly a function of the application (gasconcentration and frequency of exposure to target gas). Thepurpose for calibration is to compensate for any possible decreasein sensor sensitivity. The primary cause of sensitivity decrease isexcessive loss of water by evaporation. A secondary cause maybe by contamination from unknown sources. H2S sensors show anadditional decrease in sensitivity due to internal sulfur formation, therate of which depends on the gas concentration.Interscan’s SENSOR EXPRESS® program streamlines downtimeby sending you a pre-calibrated sensors on a regular basis per yourneeds, without the burden of returning sensors to our factory for re-certification. The sensors are shipped to you either twice , threetimes, or four times per year at your discretion.Follow the instructions received with the Sensor, allow to stabilize,and the instrument is ready for use. The factory recommendedprocedure for calibrating all INTERSCAN analyzers, involves theuse of certified calibration gas or a permeation device. Besidesbeing essential for calibration, having a known certified gasstandard on hand allows the user to test the analyzer at any time todetermine that it “really works”As indicated on the certification sheet, the Sensor Express®. It doesnot certify the analyzer as a whole. Most importantly, the SensorExpress® program is not a substitute for basic analyzermaintenance, nor does it check for malfunction of the analyzercomponents.Whatever the source of calibration gas, the recommended method is to collect the gas in the proper sample bag, which is then attached to the analyzer INLET. The calibration gas is drawn from the proper sample bag through the sensor. An exception to the use of a sample bag is for those gases, which are reactive with, or chemisorbed by the bag itself (e.g. Chlorine, Hydrazine). Teflon® or Tedlar® bags are suitable for H2S, SO2, NO and NO2. Several bag materials are suitable for CO. Contact the Factory for recommendations.The sample bag method is the factory-recommended method for calibration. Since an internal pump is used, the same flow rate conditions during the sample and the calibrate modes are assured, eliminating errors due to flow rate differences. For most applications, using a bag is the simplest procedure.A regulated pressurized certified cylinder fitted with a tee-manifold (fig. 6) and unrestricted vent is a good procedure in place of the sample bag, as long as the flow rate of the gas is at least 140 percent that of the sample pump.(fig. 6)Analyzer must be zeroed prior to calibration (sec 2.1).1. For all gases, except Chlorine or other chemisorbable types, fill the 5 litersample bag with calibration gas, and attach it to the external inlet fitting.This is best done by attaching a short length 4 inch (101.6mm) of 1/4 inch(6.35 mm) O.D. Teflon tubing to the sample bag, then inserting into theinlet fitting.2. Set the FUNCTION switch to SAMPLE ACTIVE.3. Allow 2 to 3 minutes for the reading to stabilize, and by using theSPAN/CAL control, set the display to match the calibration gas concentration being used.4. Remove the sample bag from the analyzer and allow the display tostabilize.5. The analyzer is now calibrated and set up for operation.NOTE: If you require additional information on Calibrationprocedures, please contact the Service Department at 1-800-458-******************************************General MaintenanceBecause of current requirements of the circuitry, “C” size alkalinebattery life should be check on a monthly basis, whether the unit isoperating or not. Note: Batteries vary in capacity bymanufacturer and may provide more battery life. Analyzermalfunction, as a result of low battery, will be evident as eitherinability to zero the monitor or clipping of the display at a fixedreading below full scale.Nickel-cadmium battery life is indeterminate. It is somewhatdependent upon how well the charge level is maintained.All models of the 4000 Series analyzers use two “C” size alkalinebatteries. These are located on the hinged door, right side (fig. 4 pg.8). Polarity is marked on the door over the battery holder.A few minutes warm-up/stabilization is needed before using theanalyzer if alkaline batteries are replaced before Battery Test “B”indicates a low battery condition (100). Replace “C” alkalinebatteries and allow monitor to stabilize overnight if the batteries arelow or dead. The FUNCTION switch should be set to OFF duringthis time. This is performed to allow the sensor time to stabilize.The rechargeable batteries are ½ “C” size NiCd and are rated at0.80 ampere hours. They are mounted on the hinged door, left side(fig. 4 pg. 8). Polarity is marked on the door, over the battery holder.All models use four ½ cell “C” size NiCd batteries. Condition isshown in the BATTERY TEST “A”, FUNCTION switch position. TheNiCd battery voltage changes quite rapidly as it approaches therecharge point, which makes accurate display indication difficult. Itis recommended that the batteries be recharged if the reading inBATTERY TEST “A” is at 100 (ignoring the decimal place). Allowingthe reading to drop below 100 is not recommended. Note: NiCd batteries can develop cell memory. Cell memory is caused by running the analyzer on battery power for a short period of time REPEATEDLY i.e: Running the analyzer for 20 minutes and then recharge. If this occurs repeatedly, the NiCd battery life will only retain a 20 minute charge memory.The charger is an external 9V DC, 500mA transformer and is connected to the rear of the unit prior to charging. The tip is positive and the ring ground. The FUNCTION switch should be set to OFF or SAMPLE INACTIVE when charging. The recommended charge time is 16 hours.(fig. 7)All sensors provided with a fill port require that the electrolyte matrix is maintained in a near-saturated condition in order to provide optimum performance. This is achieved by injecting distilled or deionized water into the sensor via the red plug, using the plastic syringe (provided).Refer to (fig. 7 pg. 16). Refillable sensors are identified by the red fill plug in the side of the sensor. The fill plug location may vary from(fig. 7 pg. 16). There are two types of refillable sensors. The S-type is a shorter sensor of slightly over 2 1/2 inches ( 64 mm) in height; the P-type is almost 4 inches (104 mm) in height. “P” and “S” type sensors connect to the analyzer by different connection methods.For portable survey monitors, the sensor should be removed and weighed every 1 to 2 months, depending upon usage. The weight loss is indicated on the weight label on the side of the sensor. Sensor weight is restored be removing the sensor from the analyzer and comparing the current weight of the sensor with its original weight (in grams). Sensor weight is indicated on a label located on the side of the sensor.There are three types of gas fittings used depending on the age of the original sensor and the gas being measured.(fig. 8)Male elbow ¼ O.D. tube compression fittingThis is a compression fitting comprised of the body, nut and two ferrules (fig. 8). Disconnect by loosening the nut until the tubing can be pulled away from the body. To re-attach insert the tubing and tighten the nut. Do NOT over tighten the nut as this will damage the nut and fitting(fig. 9)Quick connect male elbowThis is a quick connect system comprised of the body, o-ring and ferrule (fig. 9). Disconnect by pushing on the ring where the tubing enters the fitting and gently pulling on the tubing. Re-attach by inserting the tubing all the way in and then gently pull backward.(fig. 10)Barbed male elbowThe fitting uses a barbed connector system (fig. 10). Disconnect by pulling on the tubing. Re-attach by pushing the tubing onto the fitting until firmly seated.Fig. 11For P-type sensors refer to (fig. 11). Disconnect the 2 electrical connections to the sensor. Disconnect the tubing from each gas fitting. Loosen the screw indicated as “A”. Loosen the clamp screw “B” until the sensor can be removed from clamp.NOTE: DO NOT REMOVE ANYTHING ELSERestore the sensor to within 5 grams original sensor weight by injecting an equivalent cc of distilled or deionized water (10g. weight loss means add 10cc water). DO NOT OVERFILL. If sensor will not take on any more liquid (liquid starts coming out the fill port) do not attempt to add additional distilled water.Note: Weight loss in excess per sensor weight label may prevent the restoration of the weight to within 5 grams of the original weight.DO NOT OVERFILL. After weighing and refilling replace the sensor in the analyzer, tighten screw “B” taking care only to make it tight so as to secure the sensor. Then tighten screw “A”, do not over tighten.Assure that all electrical and pneumatic fittings are secure. The sensor should be allowed to stabilize forseveral hours with power off.(fig. 12)For S-type sensors refer to (fig. 12). Disconnect the two electrical connections to the sensor. Disconnect the tubing from each gas fitting. Remove the two Sensor Screws (# 7).NOTE: DO NOT REMOVE ANYTHING ELSE!!Restore the sensor to within 5 grams original sensor weight by injecting an equivalent cc of distilled or deionized water (10g. weight loss means add 10cc water). DO NOT OVERFILL. If sensor will not take on any more liquid (liquid starts coming out the fill port) do notattempt to add additional distilled water.Note: Weight loss in excess per sensor weight label may prevent the restoration of the weight to within 5 grams of the original weight.DO NOT OVERFILL. After weighing and refilling replace the sensor in the analyzer, tighten screws on the rear of the analyzer. Assure that all electrical and pneumatic fittings are secure. The sensor should be allowed to stabilize for several hours with power off.Turn FUNCTION swit ch to “OFF” position. Disconnect charger from analyzer. Detach 15 pin “D” connector from circuit board. Remove alkaline batteries and cover analyzer to protect from dust.24 Hours Before Using:Uncover the analyzer. Install FRESH alkaline batteries. Reconnect 15-pin “D” connector from circuit board. Connect the charger to the analyzer to charge NiCd batteries.After 24 Hours:Follow instructions in Section 2.0. Analyzer is ready to use or calibrate.WarrantyINTERSCAN CORPORATION warrants portable analyzers of itsmanufacture (sensors, batteries, fuses, lamps, tubing, fittings,filters, and scrubbers excepted) to be free from defects in materialand workmanship for a period of one year from date of shipment.INTERSCAN CORPORATION warrants sensors of its manufactureto be free from defects in material and workmanship for a period ofsix months from date of shipment.INTERSCAN CORPORATION'S sole obligation under thiswarranty is limited to repairing or replacing, at its option, any itemcovered under this warranty, when such item is returned intact,prepaid to the factory (or designated service center).This warranty does not apply to any of our products which havebeen repaired or altered by unauthorized persons, or which havebeen subject to misuse, negligence, or accident, incorrect wiring byothers, installation or use not in accordance with instructionsfurnished by the manufacturer, or which have had the serialnumbers altered, effaced or removed.

Gases present in the environment, other than the "target" gas of measurement, may affect analyzer response. Interferences are not necessarily linear, and may also exhibit time dependent characteristics.The charts that follow detail the approximate concentration in parts per million of interfering gas required to cause a 1 ppm deflection in the chosen analyzer. In many cases, specificity can be improved. Please note that the response values given are not absolute, and may vary depending on sensor formulation.The special case of how alcohols affect electrochemical sensors is discussed in this Knowledge Base article. ()For further information on the effects of interfering gases, please contact the factory.The charts follow the format, and grouping of gases, that was originally established in early Interscan print brochures.Chart 1: CO, Cl2, ClO2, H2, H2S, NO, NO2, O3, SO2 analyzersChart 2: Ethylene oxide (EtO) (C2H4O) analyzersChart 3: Formaldehyde (HCHO) analyzersChart 4: HCl, HCN, hydrazine analyzersChart 5: C2H4 (ethylene) analyzers(1) Data shown for H 2S models with ranges higher than 0-1999 ppb (2) Data shown for H 2S models with ranges of 0-1999 ppb and lower‡ = Hydrocarbons¤ = Rejection ratio can be improved electronically¶ Isopropyl alcohol represents the most significant interference on the ethylene oxide sensor, but in nearly all cases, potential problems can be overcome. Typical remedial actions include:a. Point shutdown/automatic restart, which allows the operator to temporarily interrupt monitoring at points that could be affected when isopropyl alcohol is used. Monitoring restarts automatically on a time-adjustable basis.b. Selection of monitoring points away from those areas that may be unduly affected by isopropyl alcohol.c. Using alternative germicides, which do not contain isopropyl alcohol.The EtO sensor may also respond to strong odors of colognes and perfumes, and to certain floor strippers and waxes. Refer to guidelines above covering isopropyl alcohol. Remember that you are attempting to monitor parts per million levels of ethylene oxide in an environment that may contain percent (10,000 ppm = 1 percent) levels of these potentially interfering compounds.= Negative interference= Negative interference § = Scrubber available= Negative interference= Negative interferenceAppendix B SCRUBBER INFORMATION。

压力和差压变送器详细详解使用说明书
压力与差压变送器详细使用说明(一)差压变送器原理与使用本节根据实际使用中得差压变送器主要介绍电容式差压变送器。
1、差压变送器原理压力与差压变送器作为过程控制系统得检测变换部分,将液体、气体或蒸汽得差压(压力)、流量、液位等工艺参数转换成统一得标准信号(如DC4mA～20mA 电流),作为显示仪表、运算器与调节器得输入信号,以实现生产过程得连续检测与自动控制。
差动电容式压力变送器由测量部分与转换放大电路组成,如图1、1所示。
图1、1 测量转换电路图1、2 差动电容结构差动电容式压力变送器得测量部分常采用差动电容结构,如图1、2所示。
中心可动极板与两侧固定极板构成两个平面型电容H C与L C。
可动极板与两侧固定极板形成两个感压腔室,介质压力就是通过两个腔室中得填充液作用到中心可动极板。
一般采用硅油等理想液体作为填充液,被测介质大多为气体或液体。
隔离膜片得作用既传递压力,又避免电容极板受损。
当正负压力(差压)由正负压导压口加到膜盒两边得隔离膜片上时,通过腔室内硅油液体传递到中心测量膜片上,中心感压膜片产生位移,使可动极板与左右两个极板之间得间距不相对,形成差动电容,若不考虑边缘电场影响,该差动电容可瞧作平板电容。
