The Campbell Scientific Temperature Probe 107 is a rugged, accurate probe that measures the temperature of air, soil, or water from -35° to +50°C. It easily interfaces with most Campbell Scientific dataloggers and can be used in a variety of applications.
The Temperature Probe 107 consists of a thermistor encapsulated in an epoxy-filled aluminium housing. The housing protects the thermistor allowing you to bury the probe in soil or submerge it in water.
When exposed to sunlight, the 107 should be housed in a 41303-5A, 41303-5B, or RAD06 6-plate radiation shield. The louvred construction of these radiation shields allows air to pass freely through the shield, thereby keeping the sensor at or near ambient temperature. The shields’ white colour reflects solar radiation.
The RAD06 uses a double-louvered design that offers improved sensor protection from driving rain, snow, insect intrusion and has lower self-heating in bright sunlight combined with higher temperatures (> 24°C [~75°F]) and low wind speeds (< 2 m/s [~4.5 mph]), giving a better measurement.
The 41303-5A and RAD06 attach to a crossarm, mast, or user supplied pipe with a 2.5 to 5.3 cm (1.0 into 2.1 in.) outer diameter. The 41303-5B attaches to a CM500-series pole or a user-supplied pole with a 5.1 cm (2.4 in.) outer diameter.
The 107 is suitable for shallow burial only. Placement of the sensor’s cable inside a rugged conduit may be advisable for long cable runs—especially in locations subject to digging, mowing, traffic, use of power tools, or lightning strikes.
The sensor can be submerged to 15 m (50 ft) or 21 psi. Please note that the 107 is not weighted. Therefore, the installer should either add a weighting system or secure the sensor to a fixed, submerged object, such as a piling.
