    Short Cut is an easy way to program your datalogger to measure the 107 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 11 Model 107 Temperature Probe In the search box under the Available Sensors and Devices heading, type in 107 or find the 107 in the Sensors | Temperature folder. Double-click the 107 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 12: Overview

    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.

    A complete program example can be found in Appendix B, Example Programs (p. B-1) If the 107 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,...

  • Page 15: 7.2.1 Therm107() Instruction

    7.2.1 Therm107() Instruction The Therm107() measurement instruction programs CRBasic dataloggers to measure the 107 probe. It applies a precise excitation voltage, makes a half- bridge resistance measurement, and converts the result to temperature using the Steinhart-Hart equation. See Section 8.2, Measurement and Output Linearization , for more information.

    The 60 Hz and 50 Hz integration options include a 3 ms settling time; longer settling times can be entered into the Settling Time parameter. Campbell Scientific suggests doubling the settling time every 50 ft. The following code snip examples increase settling time by 20000 µs by placing 20000 as the...
