MODEL CS205
10-HOUR FUEL TEMPERATURE STICK
1. GENERAL DESCRIPTION
The CS205 Temperature Stick is a Ponderosa
pine dowel 4.5 inches long and 0.5 inches in
diameter. The dowel is fabricated to USFS
specifications, to be used as a fuel moisture
sensor. Campbell Scientific, Inc. has bored a
hole and cut a split into one end of the dowel. A
model 107 Temperature Probe is inserted into
the CS205 to measure fuel temperature.
The CS205 Fuel Temperature Stick mounts on
the 10974 Fuel Moisture/Temperature
Mounting Stake. The CS205 is most commonly
installed along with a CS505 Fuel Moisture
Sensor but can be used alone.

3. INSTALLATION AND WIRING
Insert a 107 temperature probe into the CS205
Fuel Moisture Stick. The CS205 installs in the
white compression fitting on the 10974 Fuel
Moisture/Temperature Mounting Stake.
Loosen the compression fitting so that the
CS205 can be inserted. The CS205 inserts
into the compression fitting so that compression
is applied to the split end of the stick gripping
the 107 probe.
Connections to the datalogger for the 107 are
shown in Figure 1-1. The probe is measured by
a single-ended analog input channel. The red
lead is connected to either a HI or LO input.
The black lead connects to any excitation
channel.
Please refer to the 107 probe manual for a
complete discussion of the 107 probe.
4. PROGRAMMING
Instruction 11 is used to measure temperature.
Instruction 11 provides AC excitation, makes a
single ended voltage measurement, and calcu-
lates temperature with a fifth order polynomial.
A multiplier of 1.0 and an offset of 0.0 yields
temperature in Celsius. For Fahrenheit, use a
multiplier of 1.8 and an offset of 32.
