Model 107 Temperature Probe
8. If LoggerNet, PC400, RTDAQ, or PC200W is running on your PC,
and the PC to datalogger connection is active, you can click Finish in
Short Cut and you will be prompted to send the program just created
to the datalogger.
9. If the sensor is connected to the datalogger, as shown in the wiring
diagram in step 6, check the output of the sensor in the datalogger
support software data display to make sure it is making reasonable
measurements.
5. Overview
The 107 is a rugged probe that accurately measures air, soil, or water
temperature in a variety of applications. The sensor consists of a thermistor
encapsulated in an epoxy-filled aluminum housing. This design allows the
probe to be buried or submerged in water to 15 m (50 ft) or 21 psi. When
measuring air temperature, a 41303-5A radiation shield is normally used to
mount the 107 and limit solar radiation loading. See Specifications for a
complete list of compatible dataloggers.
