RAWS-F Remote Automated Weather Station for Fire Weather

4.5.1.2 Wiring

The 034B-LQ attaches to the connector labeled WS/WD; this connector is

color coded red. The sensor is internally wired from the RAWS connector

panel to the CR1000.

TABLE 4-4. WS/WD Connector (color coded red)

Connector Pin Description CR1000 Terminal

A Sensor Ground

B Wind Direction Excitation VX2

C Wind Direction Signal 2H

D Power Ground G

E +12 V Power 12V

F Wind Speed Signal P1

4.5.1.3 Maintenance

The wind vane tail must be attached to the hub. Maintain the tail assembly

with the tail vertical. Extra labels are included with the wind sensor to recover

the holes if the sensor has to be disassembled for maintenance. The set screw

holes must be covered with these labels to prevent corrosion and ensure the

warranty. Verify free movement of the cup anemometer and wind vane.

4.5.1.4 Calibration

Recalibrate the wind sensor annually. Obtain an RMA number before

returning this sensor to Campbell Scientific for recalibration.

4.5.1.5 Troubleshooting

If a problem is suspected, 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 an RMA number before

returning this sensor to Campbell Scientific for repair.

4.5.2 2-D WindSonic (optional)

4.5.2.1 General Description

The Gill Instruments 2-D Sonic Wind Sensor (pn WindSonic4-QD) shown in

FIGURE 4-5 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,

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.
