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. Technical grade denatured or isopropyl alcohol may be used where the dust accumulation does not respond to brushing. Do not use water. Always disconnect the power when perform-ing a cleaning operation.Aside from field calibrations for span, 4 mA and 20 mA set-ting as described above, the Series 641RM Air Velocity Transmitter cannot be fully factory calibrated in the field. Because of specialized computer instrumentation required, these units must be returned to Dwyer Instruments for fac-tory calibration.

KGF3型风速传感器
KGF3型风速传感器1 概述1.1 用途KGF3型风速传感器是根据卡曼原理开发的用来测量风速的一种智能型传感器，可以用来检测煤矿井下各种巷道、风口处的风速，可与各种类型的监测系统配套使用。
该传感器性能稳定、使用方便，并能通过遥控器进行现场调整。
1.1 防爆型式防爆型式：矿用本质安全型，防爆标志“ExibI”。
1.2 使用环境条件a.温度：0℃～40℃；b.相对湿度：≤95%（+25℃）；c.大气压力：80～106 kPa；d.含瓦斯、煤尘等爆炸性混合物气体、但无显著振动、冲击、淋水的场所。
2 工作原理根据卡曼原理，在流体中插入一个非流线阻力体，当雷诺系数Red在200～5×104范围内时，在阻力体下游将产生两列交替出现的旋涡列，称为卡曼涡街，其旋涡频率与流体的流速成正比。
因此，只要测得频率f，就可以得到流速V。
传感器的超声波振荡器产生等幅超声波振荡信号，该信号加到发射换能器上，并向空气中发射超声波。
此时，接收换能器接收到被旋涡调制的超声波。
该超声波信号经高频放大、检波、低频放大、整形后，变成对应的脉冲信号，再输入单片机进行规一化、非线性补偿处理，然后由LED显示风速值并变成标准的电信号输出。

Introduction & Overview – 30.5 Wind Sensor1.1. OverviewThe 30.5 Wind Sensor provides measurements of wind speed and wind direction in a single, compact, rugged unit. It integrates a folded-path, low-power sonic anemometer. It also includes an internal compass that allows for automatic alignment of wind direction to magnetic north, regardless of the sensor’s orientation.The small footprint and power efficiency of the 30.5 make it ideal for remote regions, urban environments, air quality networks, construction/remediation sites, and other network applications. The sensor works well in permanent (cooperative weather networks, schools, public information dissemination) or temporary (emergency response, audit, research program support) installations.Designed for maximum portability and utility, the 30.5 is well suited for rapid deployment and use by one person under all conditions. The unit may be mounted on a tower, tripod, or vehicle mast. Data outputs are a serial, digital message as well as simple analog voltage outputs that can be interfaced to most data logging systems.2.

Operational CheckoutConnect the 30.5 serial or analog signal wires to a data logger or recording device. Connect power to the sensor cable per wiring diagram in section 3.3. The 30.5 will automatically start measuring wind speed and direction and outputting data on both the serial and analog outputs. Any connected recording electronics should start displaying or recording measurements from the 30.5. Verify the data seems reasonable by comparing it to data from a local weather source. If the data looks OK, the unit is in operation. If data is questionable, contact Met One Instruments, Inc. Service Department for further guidance (see the Technical Support section at the beginning of this manual).3.5. MaintenanceThe unit has no moving parts and therefore requires no periodic maintenance for wear items. It is recommended that the data be checked every 6 -12 months to be sure there has been no failure of any of the electrical components. This can be done by placing a small container (at least 12inch diameter) over the sensor to zero check the wind measurement. The wind readings can be checked against a collocated wind sensor. The 30.5 sensor can also be returned to Met One for wind tunnel verification / calibration. 3.6. Setting Magnetic DeclinationThe internal compass automatically corrects the wind direction in the 30.5 to magnetic North. This means that the unit will not require directional alignment or orientation upon deployment.If it is necessary to measure wind direction referenced to True North it is important to understand and know the magnetic declination of the area in which the sensor is being operated. The declination in the 30.5 is factory set at zero degrees. To change this, refer to the MD command instruction in section 7.1.10 for setting the Magnetic Declination.4.

User InterfaceThe output of the 30.5 is a fixed length, comma delimited, serial data stream. The serial output is factory set for 9600 baud, no parity, 8 data bits, 1 stop bit, and no flow control. The output interval default is once per second. This may be changed using the OI command (see Appendix A). The data is easily viewed and can be displayed and captured using Met One Instruments’ Comet Software or other terminal communication program.An example of the standard output format is shown below:000.6,272,U0,*02257 CR/LFEach parameter is a fixed length with leading zeros separated by a comma. The string terminates with a Carriage Return and Line Feed. Field parameters are defined as: 000.6,272,+23.1,12.7,090,U0,*02257 CR/LFWS,WD,AT,BV,COMP,CONFIG,CheckSumNote thatThe wind speed and temperature units can be changed with the SU and TU terminal commands, respectively. Please refer to Appendix A for more information. NOTE: Ambient Temperature, Compass reading, and Battery Voltage values are OFF by default in the output string, and can be added using the AT, CV, and BV commands, respectively.; see Section 7.1.2 for details and an output string example.A check sum parameter is added to the end of the message (ex: *02257).The check sum is the addition of all the characters from the start of the message through the first character preceding the asterisk (*). The check sum is expressed as a decimal number. This is a 16-bit sum and should not overflow past 4 digits given the number of characters in the output string.Polled data mode (RS232 or RS485)The sensor can be set for polled data mode instead of continuous serial output by setting the OI command to Zero and using the serial trigger string to request a data string. Refer to the ST terminal command in Appendix A for instructions on setting the Serial Trigger.6. Standard ConfigurationSerial InterfaceThe serial interface is fixed at 9600 Baud and configured for No Parity, 8 Data Bits and 1 Stop Bit, with no flow control.Analog InterfaceThe analog outputs for Wind Speed and Wind Direction are fixed at 0-1VDC.Wind SpeedThe Wind Speed unit choices are m/s or mph. The default is M/S. The Speed range for M/S is 0-60. The Speed range for MPH is 0-134.TemperatureThe Temperature unit choices are Degrees C or Degrees F. The default is Degrees C.

MD –Magnetic DeclinationThe automatic alignment compass in the 30.5 sensor provides Wind Direction automatically adjusted to MAGNETIC north. Software in the Interface allows the setting of a declination angle to correct the Wind Direction output to TRUE north. It is recommended that this procedure be done in the lab but can be done in the field as well. Once the declination angle is set in the sensor, it is stored in non-volatile memory, and does not have to be reset each time the sensor is fielded. The declination angle must be reset only if the system is used in a different geographical location separated by many miles from the location where the declination was originally set.It is suggested that the magnetic declination be determined before performing this calibration. Visit the following web site for help in determining the correct declination for the installation site:/geomag/declination.shtmlClick “Compute your declination”. On the next page, enter either zip code, or select country and city, then click “Get Location” and then “Calculate”. Alternatively, longitude and latitude can be entered, and then click “Calculate”. Declination is reported in Degrees, Minutes and Seconds. Divide minute’s value by 60 to get decimal fraction of degrees (I.E. 50 minutes = 0.8 degrees). If the declination needs to be adjusted, please use the MD command as shown below.Read or Set the Magnetic DeclinationCOMMAND RESULTMD<cr> Report Magnetic Declination settingMDXX.X<cr> Set Declination to XX.X DegreesNote: West declination values are entered and reported as negative values.7.1.11.

Modbus operation:The 30.5 can be queried for data using the Modbus RTU protocol. The 30.5 will automatically detect a Modbus data request via its standard RS-232 or RS-485 interface, and will change to Modbus mode, ready to send out data as requested by a connected Modbus Master.If the 30.5 is to be used as a Modbus device, it is recommended to set the Output Interval (OI) command to 0 (zero) to turn off the 1/second output, as shown in section 7.1.11. This will prevent any serial traffic conflicts.The 30.5 can be assigned a Modbus address between 1 to 247, which allows it to be addressed on a multiple device network. Setting the Modbus address to 0 will disable the Modbus functionality of the 30.5. The 30.5’s current measurement data can be polled via Modbus using the 3X and 4X register addresses: 3X RegistersModBus Name Addr Type PointsMB_123456 = 0 float 2 Known value for easier Byte Order configurationMB_SN = 2 Char 5 Serial Number StringMB_Revision = 7 char 20 39 Char + Zero Terminator word aligned to 40 bytesMB_WS = 100 float 2 Wind SpeedMB_WD = 102 float 2 Wind DirectionMB_AT = 104 float 2 Ambient TemperatureMB_Batt = 114 float 2 Supply VoltageMB_Comp = 116 float 2 Compass Heading4X RegistersModBus Name Addr Type PointsMB_Byte_Order = 0 Int 1 1 thru 49. Appendix B9.1. Theory of OperationWindThe Met One 30.5 sonic anemometer operates on the principal that the speed of the wind affects the time it takes for sound to travel from one point to a second point. If the sound is traveling in the direction of the wind, the transit time is decreased. If the sound is traveling in a direction opposite the wind, the transit time is increased. This is used to measure air movement in two perpendicular axes, which are used to calculate Wind Speed and Wind Direction.Ambient TemperatureThe temperature sensor in the 30.5 measures air temperature for the purpose of calculating the wind measurements only. It is not designed to comply with EPA or WMO ambient temperature measurement guidelines.Automatic Alignment CompassThe internal compass module is low power and compact. It employs a pair of magneto-resistive sensors, which change with varying magnetic field strengths, to sense the Earth’s magnetic field.The 30.5 microprocessor measures the output of the internal compass and then corrects the wind direction data for the orientation of the sensor. The output of the 30.5 wind direction is relative to magnetic North. A user programmable value of Magnetic Declination may optionally be entered through terminal mode. This enables wind direction output relative to True rather than Magnetic North.。

DECLARATION OF CONFORMITY (16)Page intentionally left blank1. GeneralThe wind sensor combination OMC-160 consists of the wind speed sensor and wind direction sensor. The system is robust, lightweight, corrosion resistive and easy to install.The wind sensor is a rotary-cup type unit made from stainless steel. The 3 cups are helicoid shaped, 80 mm in diameter, with an outer spin diameter of 130 mm. Rotation of the cup-unit generates 8 pulses/rotation in an optical encoder. The encoder is directly connected to the micro processor which converts the pulses to wind speed in M/S.The wind direction sensor is a wind vane type unit, made from stainless steel. The wind vane drives a resolver, from which the reference coils are connected to the microprocessor. The micro processor translates the sine and cosine output from the resolver into a direction signal.The microprocessor transmitter is completely encapsulated to withstand extreme environmental conditions. It converts both the optical pulses from the wind speed and the resolver position from the wind direction, into a combined digital signal (serial current loop, 300 bps, ASCII code). This signal can be transmitted over cable lengths up to 1200 meters, but it can also be transmitted via VHF or other data-communication systems. The transmitter unit requires a 8- 30 volts dc supply, which is usually supplied by the indicator coupled to the wind sensor (typically 15Vdc).De-icing heatersAs an option, the wind sensors may be equipped with de-icing heaters. These heaters are located in the top part of the sensors. By heating the bearing-housing, it prevents the rotating parts freezing to the housing in case of precipitation at low temperatures. The heaters (24 Volts ac or dc, 35 Watt) are controlled by a thermostat in the sensor housing.1.1 Data summaryPower supply: 8 TO 30 VDC 60 mAOutput: Currentloop ASCII coded output 20 mA2.30NMEA-0183versionkgWeight: 6.5Dimensions: 865x248x465mm (DxWxH) see sketch chapter 8 Mounting pole: max. 65 mm diaOperating temperature: –25 to 70°CMoisture protection: IP65Humidity: 10 to 95%Accuracy: Wind speed: better than 2% FROWind direction: better than 3 degreesSpeed range: 0,3…75 m/sClass: EMC EN 50081-1 class B, EN 50082-2Conform RoHS directive 2002/95/EC en 2005/18/EC2. Installation2.1 MechanicalThe wind sensor OMC-160 is supplied with the mounting bracket and junction box. This can be mounted on a vertical pipe with external diameters between 35-60 mm using the U-bolt clamps supplied.Before starting the installation, make sure that all components are complete, and that the mast is properly fixed to withstand rugged wind forces. The wind-sensors are usually shipped with the wind vane and cups disconnected from their appropriate units. On the common unit, the upper spindle is for the wind direction sensor, and the lower spindle for the wind speed sensor. To prevent damaging the wind vane and cups, properly mount thesensor/bracket combination on the mast before fitting the wind vane and cup-unit. (this may not always possible)Ensure that the sensors are mounted high enough to avoid any turbulence from obstacles. For guidance refer to the WMO publication ’Guide to Meteorological Instruments and Methods of Observation’ (latest issue).On completion of the above installation carry out the setting-up procedure as contained in the commissioning paragraph 3.1.2.2 ElectricalThe mounting bracket is provided witha junction box for connection of the fieldcabling. The combined wind sensor onlyrequires a 4-core cable (2 twisted pairs, 0.75mm2, common screen). In case that thesensors are equipped with de-icing heater, a6-core cable is required with 2 extra coresfor the heather.Because the current drawn by the heateris ±2 amp the cable from the sensor to thejunction box should be as short as possibleto prevent loss of power. For the cable fromthe junction box to the heater transformer thecable size depends on the length of thatcable.The field cable should be properlysupported, and fastened to prevent exertingforce on the terminals. The common screenof the cable must be grounded to earth onone end only, inside the junction box of thewind sensor.3. CommissioningBefore commissioning the wind sensor, check that the display is properly connected and the power is switched on. The display normally provides the 15 volts dc power supplyto the wind sensor, which can be measured between terminals (1) and (2) at the rear of the display. The wind speed sensor needs no further commissioning, it will automatically transmit the measured speed.3.1 Align procedureLand-based:The wind direction sensor needs alignment. In land based systems the OMC-160 shouldbe aligned to North. After alignment the OMC-160 wind sensor will report "absolute" wind direction. This way of alignment is also used on most fixed offshore rigs.Ship-based:On ship based systems the OMC-160 should be aligned to the bow of the vessel. After alignment the OMC-160 will report "relative" wind direction. This way of alignment is also used on small buoys and on some offshore objects as F(P)SO’s.For the purpose of alignment the sensor is provided with an LED located in the junction box mounted on the mounting bracket which will light-up when the sensor transmits a direction signal around zero degrees (between 350 and 010 degrees):1. Open the cover of the junction box that is located on the mounting bracket toobserve the LED.2. When the color of the LED is green the sensor transmits a direction between002 to 010 degrees.3. When the color of the LED is red the sensor transmits a direction between the350 an the 358.4. When the color of the LED turns yellow the transmitted signal is "North" or 0degrees, within a band width of 2 degrees.5. For land based alignment locate North by using a hand held compass or similar.6. Unscrew the locknut of the wind vane7. Put a screwdriver in the groove of the vane-shaft and set the counterweight ofthe wind vane pointing to North or the ships bow, and keeping it in thisposition, slowly turn the shaft with the screwdriver until the LED lights up.8. Fine adjust the shaft until the LED lits yellow (i.e. North or 0 degrees within 2degrees)9. Tighten the lock-nut of the wind vane, taking care that the vane does not move onthe shaft.10. Check the "North" transmitting signal with LED after tightening the vane locknut.11. Close the junction box cover.Remark:Depending on local circumstances, it may be more practical to align the wind vane with the sensor mounting bracket and adjust the wind vane shaft until the LED light. The mounting bracket can then be aligned to the north by rotating the complete mast, thus aligning the wind vane to the North.4. Sensor body4.1 MaintenanceThe OMC-series wind sensors are designedfor low maintenance and all components are conservatively rated. The only componentsthat are likely to require replacement due to normal wear are the precision ball bearings. Replacement of these components should only be attempted by a qualified technician. Itshould be carried out in a workshop free fromdirt and impurities.Refer to assembly drawings of wind speedand, wind direction sensor for part names and locations. First remove the cup-unit or vane-unit from the body by unscrewing the locknutand lifting the unit. To gain access to the bearings remove the bearing housing by unscrewing the 3 screws on the side of the body. When lifting the bearing housing, the attached transmitter block in the speed sensor,or the resolver in the direction sensor will alsobe pulled out with the attached wiring. Before disconnecting this wiring mark the original connections.In the wind speed sensor the transmitter block must be removed after which the columns can bescrewed off to free the bearing lock plate. The bearings can now be taken out complete with the shaft. In the wind direction sensor this is done in a similar way after removing the resolver.When the bearings are renewed, care should be taken not to apply excessive force on the new bearings.The bearing housings of wind speed and wind direction units are not identical on the OMC-160.When re-installing the complete bearing housing with the transmitter block or resolver, care should be taken that the internal wiring is properly connected, and not touching any moving part.The cable-gland in the bottom part of the body should be tightened to support the field cable.Parts with positioning numbers as used in the drawings on the previous pages.Pos Nr.

In the wind speed sensor the transmitter block is fitted to the bearing housing, and in the wind direction sensor the resolver is fitted to the bearing housing. From the wind direction resolver six signal cores are connected to the transmitter block in the wind speed sensor. The combined output signal is available on 14 screw terminals on the transmitter block. Field cabling can be connected either directly to the transmitter block terminals inside the speed sensor, or via a junction box on the mounting bracket.
