General Description

The 109-L Temperature Probe is a thermistor used with Campbell Scientific dataloggers. The 109-L probe is measured with a special instruction. The 109 is designed to primarily measure the temperature of air, but can also be used to measure water, and soil temperature. For air temperature measurements, the 41303-5A solar radiation shield is typically used to house the probe, while limiting solar loading on the sensor.

The temperature probe can also be buried or submerged to a maximum depth of 50 feet (water) or 21 psi (water/soil). The probe is not weighted for submergence (i.e. it will float), so the installer should plan to add a weighting system or secure the probe to a fixed, submerged object, such as a piling.

The 109-L has a measurement temperature range of -50° to +70°C and outputs a full scale range of 0 to 2.2 Volts. Recommended lead lengths are 25, 50, 75, and 100 feet, although the 109 may be ordered with lead lengths up to 1000 ft.

The 109-L thermistor is housed in an aluminum sheath to protect the thermistor. The 109-L is not interchangeable with either of the 107 or 108 temperature probes (i.e., the 107/108 cannot be used with Campbell Scientific dataloggers).
