    Short Cut is an easy way to program your datalogger to measure the 109SS 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 109SS 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.

    This design protects the thermistor, allowing the 109SS to be buried or submerged in harsh, corrosive environments. It can be submerged in water to 45 m (150 ft) or 63 psi. See Section 6, Specifications , for a complete list of compatible dataloggers.

    Model 109SS Temperature Probe Compliance: View the EU Declaration of Conformity at www.campbellsci.com/109ss Overall probe accuracy is a combination of thermistor interchangeability, bridge-resistor accuracy, and error of the Steinhart-Hart equation. Interchangeability is the principle component error. 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.

    (p. 8) Water Temperature Installation 109SS probes can be submerged to 45 m (150 ft) or 63 psi. The 109SS is not weighted, so a weighting system should be added, or the probe secured to a submerged object such as a piling.

    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 of cable length. The following code snip examples increase settling time by 20000 µs by placing...

    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 109SS 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.
