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.
2. Specifications
Fuel Temperature Stick
Diameter 0.5 inches
Length 4.5 inches
Wood Type Ponderosa Pine
Bore Hole about 1/4 inch
3. Installation
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.
Please refer to the 107 probe manual for a complete discussion of the 107
probe.

4. Wiring
Connections to Campbell Scientific dataloggers are given in Table 4-1.
Temperature is measured with one Single-Ended input channel and an
Excitation channel.

5. Datalogger Programming
This section is for users who write their own datalogger programs. A
datalogger program to measure this sensor can be created using Campbell
Scientific’s Short Cut Program Builder software. You do not need to read this
section to use Short Cut.
The Temp107 measurement instruction (P11), is used with dataloggers that are
programmed with Edlog (e.g. CR10X, CR23X) to measure the 107 probe. P11
makes half bridge voltage measurement, and converts the measurement result
to temperature using a fifth order polynomial. With a multiplier of 1 and an
offset of 0, the output is temperature in degrees C. With a multiplier of 1.8 and
an offset of 32, the output is temperature in degrees F.
The Therm107 measurement instruction is used with dataloggers that are
programmed with CRBasic (e.g. CR1000) to measure the 107 probe.
Therm107 makes a half bridge voltage measurement, and converts the
measurement result to temperature using the Steinhart-Hart equation. With a
multiplier of 1 and an offset of 0, the output is temperature in degrees C. With
a multiplier of 1.8 and an offset of 32, the output is temperature in degrees F.

6. Maintenance and Calibration
The 107 Probe requires minimal maintenance. Please refer to the 107 manual
for more detail.
The CS205 Fuel Moisture Stick should be changed annually or more
frequently as required. The wood should visually appear fresh and new not
gray or discolored.
