RAWS-F Remote Automated Weather Station for Fire Weather

4.6.2 Wiring, Barometric Pressure (part #CS100)

The barometric pressure sensor (part #CS100) is mounted inside the RAWS

environmental enclosure and the sensor wires are attached to the CR1000

printed circuit board wiring panel.

4.6.3 Maintenance, Barometric Pressure (part #CS100)

Since the sensor is semi-sealed, minimum maintenance is required. Change the

RAWS enclosure desiccant regularly; failure to protect the CS100 sensor from

condensation may result in permanent damage.

The CS100 is sensitive to static when the back plate is

removed. To avoid damage, take adequate anti-static

measures when handling this sensor.

CAUTION

4.6.4 Calibration, Barometric Pressure (part #CS100)

Recalibrate the CS100 Barometric Pressure Sensor annually. Obtain a Return

Material Authorization (RMA) number before returning this sensor to

Campbell Scientific for recalibration.

4.6.5 Troubleshooting, Barometric Pressure (part #CS100)

Verify the sensor wires are securely fastened to the CS100 Barometric Pressure

Sensor connector and the CR1000 printed circuit board wiring panel. Use a

DVM to check the sensor output voltage on the CR1000 printed circuit board

wiring panel (0 to 2.5 VDC) between terminals 5H and AG.

For the DVM test, “temporarily” move the green wire from “C4”

to “5V” terminal. No voltage indicates a problem with the sensor

or a bad sensor cable connection. Try connecting a substitute

sensor.

NOTE

Obtain a Return Material Authorization (RMA) number before returning this

sensor to Campbell Scientific for repair.

4.7 Fuel Moisture and Fuel Temperature (optional)

4.7.1 General Description, Fuel Moisture/Fuel Temperature

(part #CS515-QD)

The Campbell Scientific Fuel Moisture/Fuel Temperature Sensor (part

#CS515-QD) shown in Figure 4.7-1 consists of a CS505 Fuel Moisture Probe,

CS205 Fuel Temperature Stick, and 107-QD thermistor mounted on a 10974

fuel moisture/temperature mounting stake. The fuel moisture probe provides
