4.4.2 2-D WindSonic
4.4.2.1 General Description, 2-D WindSonic (part #WindSonic-LQ)
The Gill Instruments 2-D Sonic Wind Sensor (part #WindSonic-LQ) 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.
4.4.2.2 Wiring, 2-D WindSonic (part #WindSonic-LQ)
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.

4.4.2.3 Troubleshooting, 2-D WindSonic (part #WindSonic-LQ)
Check the sensor cable. Disconnect the connector and look for damaged pins.
Try connecting a substitute sensor. Should the 2-D sonic sensor be damaged,
fails to output data, or sends a nonzero diagnostic, obtain a Return Material
Authorization (RMA) number before returning this sensor to Campbell
Scientific for repair.
Consult the WINDSONIC4-L manual for more information.
NOTE
4.5 Barometric Pressure
4.5.1 General Description, Barometric Pressure (part #CS100-QD)
The Setra Barometric Pressure Sensor (part #CS100-QD) is a capacitive
pressure transducer that uses Setra’s electrical capacitor technology for
barometric pressure measurements over the 600 to 1100 milibar range. The
CS100 is supplied in the triggered mode, in which the datalogger switches 12
VDC power to the barometer before the measurement. The datalogger then
powers down the barometer after the measurement to conserve power.
4.5.2 Wiring, Barometric Pressure (part #CS100)
The barometric pressure sensor (part #CS100-QD)
is mounted inside the
RAWS environmental enclosure and the sensor wires are attached to the
CR1000 printed circuit board wiring panel.
