    Short Cut is an easy way to program your datalogger to measure the 109 probe and assign datalogger wiring terminals. Short Cut is available as a download on www.campbellsci.com. It is included in installations of LoggerNet, PC200W, PC400, or RTDAQ.
  • Page 10 Model 109 Temperature Probe In the search box under the Available Sensors and Devices heading, type in 109 or find the 109 in the Sensors | Temperature folder. Double-click the 109 Temperature Probe. Data defaults to degree Celsius. This can be changed by clicking the Deg C box and selecting Deg F, for degrees Fahrenheit, or K, for Kelvin.

  • Page 11: Overview

    Overview The 109 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.

    A complete program example can be found in Appendix B, Example Programs (p. B-1) If the 109 probe is to be used with long cable lengths or in electrically noisy environments, consider employing the measurement programming techniques outlined in Section 8.3, Electrically Noisy Environments , and Section 8.4,...

    (p. 11) 2.0 m and 10.0 m for temperature difference (EPA) • When exposed to sunlight, the 109 should be housed in a six-plate solar radiation shield. Six-plate shields offered by Campbell Scientific are models 41303-5A, 41303-5B, or RAD06. The white color of these shields reflects solar radiation, and the louvered construction allows air to pass freely through, thereby keeping the probe at or near ambient temperature.

    Maintenance The 109 probe requires minimal maintenance. For air temperature measurements, check the radiation shield monthly to make sure it is clean and free from debris. Periodically check cabling for signs of damage and possible...

  • Page 19: Calibration

    If needed, an estimate of the interchangeability error for 0 to 50 °C, that can be used as the Offset parameter of the Therm109() instruction, can be determined with a 1-point or 2-point calibration. Calibration of the 109 probe is not necessary unless the accuracy needed in the sensor data requires correction of the thermistor interchangeability offset described in Section 6, Specifications (p.
