OMEGA Engineering Model WMS-22 and WMS-22A Current Loop WindStations Instruction Manual 1.0 INTRODUCTION The WMS-22 Current Loop WindStation measures wind speed and direction and converts each paramenter into 4-20 mA output signals for use by process control or monitoring systems. No external power is required since the encoding electronics for wind speed and for wind direction are isolated and powered from their respective 2-wire current loops.
2.3 Specifications Wind Speed Measurement Range Averaging Interval Resolution Threshold Measurement Accuracy O-100 mph 2.1 Seconds 1 mph
4.2 Wind Sensor Installation Choose the mounting location for the wind sensor and temperature sensor unit which is free from obstructions. Use extreme care to prevent contact with electrical power lines while erecting the unit. A typical installation will position the wind sensor approximately 10 meters above the highest obstacle within a 300 meter radius of the mounting locations. Position the WMS-22 sensor on the end of a 1” diameter TV mast tubing or a 314” Schedule 40 pipe.
Connect the test leads of a digital voltmeter across the resistor to measure the plc lo.9 current. The measured wind speed and direction at several cardinal calibration points should correspond to the following: Wind Direction I Wind Speed (mph) V 1000 (Volts) N+ 0.0 4.0 0.4 NE = 45 ” 12.5 6.0 0.6 E = 90 ” 25 8.0 0.8 SE = 135 ” 37.5 10.0 1.0 S = 180 ” 50 12.0 1.2 SW = 225 ” I W = 270” NW = 315” I Loop Current (mA) N- I 62.5 I 14.0 I 1.4 75 16.0 1.6 87.5 18.0 1.
