RAWS-F Remote Automated Weather Station for Fire Weather

4.5.1.4 Calibration, Windset (part #034B-QD)

Recalibrate the windset (part #034B-QD) annually. Obtain a Return Material

Authorization (RMA) number before returning this sensor to Campbell

Scientific for recalibration.

4.5.1.5 Troubleshooting, Windset (part #034B-QD)

Check the sensor cable. Disconnect the connector and look for damaged pins.

Verify free movement of the cup anemometer and wind vane. Try connecting

a substitute sensor. Obtain a Return Material Authorization (RMA) number

before returning this sensor to Campbell Scientific for repair.

4.5.2 2-D WindSonic (part #WindSonic-QD) (optional)

4.5.2.1 General Description, 2-D WindSonic (part #WindSonic-QD)

The Gill Instruments 2-D Sonic Wind Sensor (part #WindSonic-QD) shown in

Figure 4.5-2 is an ultrasonic anemometer for measuring wind direction and

wind speed. It uses two pairs of orthogonally oriented transducers to sense the

horizontal wind. The transducers bounce the ultrasonic signal from a hood,

thus minimizing the effects of transducer shadowing and flow distortion. The

2-D Sonic Wind Sensor makes wind measurements at a frequency of 1 Hz and

outputs a SDI-12 signal to the datalogger.

4.5.2.2 Wiring, 2-D WindSonic (part #WindSonic-QD)

The 2-D Sonic Wind Sensor is connected to the RAWS connector panel “SDI-

12” connector COLOR CODED YELLOW. The wind sensor is internally

wired from the RAWS connector panel to the CR1000 datalogger.
