CS506-L Fuel Moisture Sensor

The CS506 reports the status of small-diameter (10-hour) forest fire fuels as percent moisture by weight (1%=1 g water/100 g dry fuel). It consists of an epoxy-encapsulated electronics package that uses time-domain reflectometry (TDR) technology to measure the moisture content of the 26601 10-hour Fuel Moisture Stick. The sensor produces a ±0.7 Vdc square-wave frequency that is read using an analog or pulse channel on a Campbell Scientific data logger. The data logger then converts the frequency measurement to percent fuel moisture via a quadratic calibration. 

Benefits and Features 

• • Compatible with most Campbell Scientific data loggers 
  • Companion product to CS205/107 fuel temperature sensor; can be mounted on the same stake 
  • Can automatically monitor changing fuel conditions without having to visit the measurement site 
  • Compatible telemetry options include spread spectrum radios, narrow-band radios, cellular phones, and satellite transmitters
