德州电子TV-114风速传感器用户手册说明书

Texas Electronics, Inc. Dallas, TX 75237 Fax.214.631.42184230 Shilling Way Tel.214-631-2490 TV-114TV-114-AWind Speed SensorUser’s Manual“Relied on Worldwide in the Most Extreme Conditions”Model TV-114 Wind Speed SensorDESCRIPTIONThe Texas Electronics, Inc. TV-114 Wind Speed Sensor is a mechanical style anemometer that measures the horizontal velocity of wind. The sensor is intended for long-term, maintenance-free operation.The TV-114 wind speed sensor is a freestanding device for measuring air velocity. The sensor consists of a lightweight 3-cup anemometer, which is mechanically coupled to an AC generator. As the cup mechanism rotates the AC generator produces an AC sine wave where the amplitude and frequency are proportional to wind speed.FEATURES & BENEFITS• Non-contacting, brushless AC generator for long-term maintenance free operation• No plastic parts for extremely long life• Precision stainless steel bearings for stability and repeatability• Crossarm included with purchase of matching wind direction sensor• Easy installation and maintenance• Over 25 years in production• Lightweight and rugged anodized aluminum exteriorINSTALLATION & MAINTENANCEInstallation consists of attaching the unit to a mast via the supplied mounting pole. If a crossarm is used, the entire unit can be bolted to a mast or attached via U-bolts.The sensor is dynamically calibrated at the factory and due to the nature of its operation should not require field calibration. Field maintenance should include occasional cleaning of the cup assembly and inspection of the internal mechanism to make sure it is free from insects and debris. In some applications, users may need to occasionally verify and document sensor accuracy with a synchronous test motor. Other possible routine maintenance involves replacing the bearing housing assembly every three to five years to maintain low starting threshold.ORDERING INFORMATIONModel # DescriptionTV-114 Wind Speed Sensor, Heavy IndustrialTV-114A Wind Speed Sensor, 4-20mA* Sensor is designed to work with TD-104-5D wind direction sensor.Optional Parts / AccessoriesT-8011M Synchronous motor for calibrationTV-114 WIND SENSORG-114 GENERATORThe chart below shows the maximum output obtainable from this generator, under a no load condition. This signal may be scaled down to fit many customer requirements.NOTES:l. Calibration may be checked by rotating the anemometer head at a known RPM. The above table shows the value that should be displayed on the indicator.2. The AC Volts column shows the output directly out of the transmitter.3. The DC Volts column shows the open circuit voltage out of the AC to DC adaptor.PROPER EXPOSURE OF METEOROLOGICAL INSTRUMENTSThe following generally recognized guidelines depict ideal sensor mounting locations. These guidelines are only suggestions to aid the user in selecting optimum representative sampling locations for a particular sensor. Reference was made to US Weather Bureau Installation criteria in preparing this data (See Reference 1).WIND EQUIPMENT:So far as available sites permit, wind sensors should be placed above the ground on a freely-exposed tower (20 feet or higher) and over terrain that is relatively level and free from obstructions to wind flow. When a compromise must be made, sensing units should be exposed at least 12 feet above any obstruction within 100 feet and at least as high as any obstruction within 100 to 200 feet of the wind equipment. Support towers or masts should not be of such bulk or shape as to create an appreciable obstruction to wind flow. Avoid sites where local obstructions may create up-or-down drafts, eddy currents or jet-flow effects. When sensors are roof-mounted, they should be installed at least 10 feet (or more) from the roof surface, depending upon the particular installation site. Turbulence and other local effects can be reduced somewhat by mounting sensors on the upwind end of the building (the end of the building exposed to the most common local prevailing winds). Horizontal-mount booms that extend from existing towers should be fabricated so that sensors will extend a distance of 5 to 10 feet from the tower assembly (dependent on tower thickness).Wind direction sensors are oriented upon installation in reference to either true north or magnetic north. True north is obtained by applying a local magnetic variation correction factor to a magnetic north compass indication (magnetic variation for a particular locality is obtainable from the nearest Weather Bureau Branch Office). Indicator readings for a true north sensor orientation will then be in terms of true geographic compass points. All U.S. Weather Bureau surface wind data used for observational network reporting purposes and general public use is given in reference to this true north format. Indicator readings for a magnetic north sensor orientation will be in terms of actual readings as would be obtained from directly viewing a magnetic compass instrument. Wind direction data at Federal Aviation Agency and other aircraft reporting facilities (for direct control tower-to-pilot utilization) is always made in reference to this magnetic north format.WarrantyTexas Electronics, Inc. (hereafter TEI) warrants the equipment manufactured by it to be free from defects in material and workmanship. Upon return, transportation charges prepaid to TEI, within three (3) years of original shipment of sensors and one (1) year of original shipment of electronics, recorders and indicators, TEI will repair or replace, at its option, any equipment which it determines to contain defective material or workmanship, and will return said equipment to purchaser, F.O.B., TEI. Texas Electronics shall not be obligated however to repair or replace equipment which has been repaired by others, abused, improperly installed, altered or otherwise misused or damaged in any way. TEI will not be responsible for any dismantling, re-assembly, or reinstallation charges.This warranty is in lieu of all other warranties, expressed or implied.

Flow Sensor Series 641RM 风速传感器的安装和操作说明说明书

Series 641RM Air Velocity TransmitterSpecifications - Installation and Operating InstructionsBulletin E-66-RMThe Series 641RM Air Velocity Transmitter uses a heated mass flow sensortechnology. It has 8 user selectable ranges from 250 FPM to 15000 FPM withcorresponding metric ranges of 1.25 MPS to 75 MPS. The Series 641RM Air VelocityTransmitter provides an isolated 4-20 mA out-put proportional to the velocity. With theoptional 1/2˝ 4-1/2 digit LED display, the Series 641RM Air Velocity Transmitter willprovide a highly visible local readout of the velocity.INSTALLATIONLocation: Select a location where the temperature will be within 32 to 140°F (0 to60°C) to mount the enclosure. The transmitter may be located any distance from thereceiver provided that the total loop resistance does not exceed 600 Ω. The probeshould be located where conditions are representative of the overall environmentbeing monitored. Avoid locations where turbulence, stagnation, or rapidly fluctuatingvelocities or temperatures are present as these conditions may affect the readings.The filter setting may be used to average velocity readings in turbulent conditions.Position: The transmitter is not position sensitive and may be mounted in anyorientation.Probe Orientation: Dots on the probe indicate the direc-tion of the calibrated airflow.Align these dots toward the source of the process air.Airflow: The Series 641RM Air Velocity Transmitter is intended for use with clean dryair. Particulates in the air may cause sensor damage. Dust accumulation may impairthe velocity measurement and will require probe cleaning.TO READ DISPLAY UNIT MUST BE MOUNTED HORIZONTALLY AS SHOWNABOVE. DISPLAY CAN BE TURNED 180 SO CONDUIT OPENING CAN BEPOSITIONED TO THE RIGHT OR LEFT.Note: Where conduit connections are not made, a 1/2˝ NPT cable seal should be used to prevent contaminants from entering the case. Where conduit connections are made, make sure that any possible condensation within the conduit will not flow into the transmitter housing.ELECTRICAL CONNECTIONThe Series 641RM Air Velocity Transmitter has been designed for easy and flexible connection to power and loop receivers. Electrical connection is made inside thebody of the device with a “Euro” style terminal block. The device features a current loop that is fully isolated from the power source. The current loop has an internal 24 V isolated supply so no external loop power is required. With full isolation, loop grounding is not a concern. The input power requirements are also very flexible. The device may be powered from either an AC or DC power source.Receiver-Transmitter Connection — The Series 641RM Air Velocity Transmitter is designed as a three or four wire 4-20 mA device. The current loop output is isolated from the power supply input and provides an internal 24-volt loop supply. With a DC power supply, a three or four-wire connection may be used. Do not use a three-wire connection with an AC power source. In a three-wire connection either power supply wire may be used as the common. The total loop resistance should not exceed 600 Ω.Power Supply Connection — The power supply may be either AC or DC. The DC power may be from 12-35 V. The power connection is not polarity sensitive so the positive and negative connections may be made to either power terminal. The AC connection may be from 10-16 VAC RMS. Do not exceed 20 VAC. When selecting a transformer please note that the specified output for transformers is at some specified current. With a load current less than the specified current transformer output may be significantly higher than the specified voltage. Transformers with secondary voltages of 10-16 VAC are recommended.Do not exceed the specified supply voltage rating. Permanent damage not covered by the warranty may result. Do not use anexternal power source on the current loop connection.Do not use a receiver with an internal power supply or use an external supply in the current loop. The current loop is poweredfrom within the Series 641RM Air Velocity Transmitter. Connecting an external supply to the current loop may destroy the transmitter. Using an external supply voids thewarranty.Do not use transformers with a secondary voltage rating greaterthan 16 VAC RMS.Interior label diagramPOWER SUPPLY AC OR DC RECEIVER4-WIRE 3-WIRERECEIVER NEGATIVECOMMONRECEIVERDC SUPPLY ONLY (EITHER POLARITY)3-WIRERECEIVER POSITIVECOMMONRECEIVERDC SUPPLY ONLY (EITHER POLARITY)3 or 4-wire connectionWire Type and Length — The wire selection for an installation is often overlooked or neglected and may contribute to improper or even intermittent operation. In all cases ensure that the connection meets all applicable national and local electrical codes. Although the 4-20 mA current loop systems are relatively immune to wire or wiring related problems, selection of the wire for some installations will be an important factor in ensuring satisfactory system operation. Twisted conductors will usually be immune to most stray electric and magnetic fields and to some extent electromagnetic fields, such as interference from RF transmitters. With twisted pair wiring the current loop and the power connections should be separate pairs. Avoid using flat or ribbon cable that has no regular conductor twist. Where interference is possible, it is recommended that shielded wire be used. The shield must not be used as one of the conductors and should be connected to ground at only one end, generally at the power supply. Similarly, if the installation uses conduit, the conduit should be connected to protective ground as specified by the applicable code and the signal wiring must not be connected to the conduit at more than one point or as specified by the code. The maximum length of wire connecting the transmitter and receiver is a function of the wire resistance and receiver resistance. The total loop resistance must not exceed 600 Ω, including the receiver resistance and wire resistance. The power supply connection must be designed so that the worst case voltage drop due to wire resistance will not cause the power supply voltage at the transmitter to drop below the specified value. Provided the power supply voltage is maintained within the specified voltage range, the Series 641RM Air Velocity Transmitter is not affected by variations in power supply voltage.TRANSMITTER SETUPThe Series 641RM Air Velocity Transmitter has been designed for easy setup. It has five configuration parameters that may be adjusted by the user. These parameters are Output Filter, Range (in English or Metric), span, 4 mA set-point and 20 mA set-point. All of these may be adjusted at any time in the field. These adjustments may also be easily returned to factory default.A set of controls and indicators are provided within the unit consisting of the select button, enter button, adjustment control, and six LED indicators. When operating normally, only the RUN LED indicator will be illuminated. During the setup operation the LED indicators will indicate the parameter selected, when it is being adjusted, and status of the adjustment process. If the unit is left in the setup mode for several minutes without any activity it will return to the normal operating mode.Two buttons and a potentiometer control the setup process.The SELECT button is used to scroll between the setup parameters. The ENTER button allows access to each parameter for adjustment.The ADJUST potentiometer is used to change the value of the parameters. Holding the ENTER button for 2.5 seconds saves the new parameter value.Making AdjustmentsThe adjustment process has three steps: select the para-meter, adjust the parameter, save the new value. These are described in the following steps.1. Select the parameter: Each time the SELECT but-ton is pressed the LED indicator will advance to the next parameter. When the last parameter, SPAN, is selected, the next time the SELECT is pressed the unit will return to RUN mode. Pressthe SELECT button until the LED indicator illuminates the desired parameter. Press ENTER. The selected indicator will begin to blink, show-ing the parameter may now be adjusted. If the unit is left in the setup mode, after several minutes it will reset to the operate mode.2. Adjust the parameter: Turn the ADJUST poten-tiometer until the desired setting is made. This may be adjusted using a small screwdriver or similar tool. Be careful not to force the control past its stops or damage will result.3. Save the parameter: To save the new parameter press and hold the ENTERbutton. The LED indicator will begin to flash at a faster rate. After about 2.5 seconds all of the LED indicators will flash when the parameter is saved. If you do not want to save the parameter press the SELECT button without entering the parameter.The adjusted value will be discarded and next LED indicator will be illuminated.Adjusting the Output FilterThe output filter may be adjusted to smooth the readings when measuring turbulent flow. The time constant may be adjusted from 0.5 seconds to 15 seconds. To adjust the fil-ter time constant, select the FILTER indicator. Press ENTER to enable adjustment. Turn the ADJUST until the desired amount of damping is achieved. To save the value press and hold the ENTER button until the LED indicators all flash, indi-cating the value was saved. To discard the adjustment press SELECT before pressing the ENTER button.1: Indicator on0: Indicator offRange SelectionThe range selection allows you to select one of eight ranges in either feet per minute (FPM) or meters per second (MPS).Ranges:FPM: 250, 500, 1000, 2000, 3000, 5000, 10000, 15000 MPS: 1.25, 2.5, 5, 10, 15, 25, 50, 75Select the RANGE indicator by pressing ENTER when the RANGE LED indicator is illuminated. The A,B,C LED indi-cators will display which range setting is currently active. Press ENTER to enable adjustment. Turn the ADJUST until the desired range indication is achieved. If you want to dis-card the adjustment press SELECT. If you want to save the range press and hold ENTER. The RANGE LED will blink at a faster rate for about 2.5 seconds then all of the LEDs will flash indicating the value was saved.The range setting is displayed with the LED indicators. The function of these indicators is summarized on the control label inside the unit. The following table summarizes the indicator status for each range settingPrinted in U.S.A. 7/21FR# 443309-00 Rev. 2©Copyright 2021 Dwyer Instruments, Inc.Span SettingThe Series 641RM Air Velocity Transmitter has been cali-brated for standard sea level conditions. As a mass flow device it will always read the air velocity for standard condi-tions. Density changes due to barometric or absolute pres-sure are not corrected automatically. The span setting allows correction for altitude or other static pressure condi-tions that affect the density of the process air. This parame-ter allows for a ±50% adjustment in the span value.To make the span adjustment you will need to know either the absolute static pressure or the corrected velocity of the process air. Set the air velocity to a known value, ideally about 3/4 of the full-scale range value. Press SELECT until the SPAN LED indicator is illuminated then press ENTER. The SPAN LED will begin to blink. Adjust the control for the desired velocity then press and hold the ENTER button until all of the LED’s flash, indicating the new value was saved. If you know the absolute static pressure you can compute the corrected velocity using the following equation:Where:P0 is the standard pressure of 29.9 in. Hg. or 760 mm Hg PA is the absolute pressure readingVrdg is the indicated velocity Vcor is the corrected velocity4 mA SettingTo make this setting you will need a milliammeter connect-ed in the current loop. It is not required to use a known air flow velocity to make this calibration setting. The calibration settings of the velocity and mA outputs are independent of each other. Press SELECT until the 4 mA LED indicator is illuminated then press ENTER. The milliammeter will now read approximately 4.0 mA. Adjust the control for a 4.0 mA reading on the milliammeter. Press and hold ENTER to save the new setting. Pressing SELECT before pressing ENTER will restore the previous calibration value.20 mA SettingIt is not required to use a known air flow velocity to make this calibration setting. The calibration settings of the veloc-ity and mA outputs are independent of each other. With the milliammeter connected in the current loop, press SELECT until the 20 mA LED indicator is illuminated. Press ENTER to begin adjustment of the 20 mA set point. The 20 mA LED will now be blinking. Adjust the control until the milliamme-ter reads 20.0 mA. Press and hold ENTER to save the new setting. Pressing SELECT before pressing ENTER will restore the previous calibration value.Restoring Factory Default SettingsThe 4 mA, 20 mA, and Range settings override factory default values. To restore these to the factory default set-tings, start with the unit in the RUN mode. Press and hold the ENTER button. The RUN LED indicator will begin to blink. After about 2.5 seconds all LED indicators will flash indicating the factory settings have been restored. Range and Filter settings are not affected by this operation. If you are unsure whether any have been altered, press the SELECT button six times to sequence through all settings. When you return to the RUN mode, the RUN LED indicator will blink several times if either the 4 mA, 20 mA, or span settings have been changed. The RUN LED will otherwise remain on.MAINTENANCEIn general the Series 641RM Air Velocity Transmitter should require very little maintenance. In some installations dust may accumulate on the sensor over time. This can be removed by carefully brushing the probe with a small camel hairbrush. If too much force is applied during cleaning, the sensor of the Series 641RM Air Velocity Transmitter may be damaged. Therefore, a trained technician should perform the cleaning operation. A jet of air may also dislodge the accumulated buildup. However, the sensor is delicate and this operation should be done carefully with clean regulated air. Using a shop air supply may exert enough force to dam-age the sensor. Most air supplies of this sort will also con-tain water or oil that could damage the sensor.
