  • Page 12: Overview

    Overview The 109SS is a rugged probe that accurately measures soil or water temperature in a variety of applications. The sensor consists of a thermistor encased in a stainless-steel sheath. This design protects the thermistor, allowing the 109SS to be buried or submerged in harsh, corrosive environments.

    Model 109SS Temperature Probe 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.

  • Page 17: Electrically Noisy Environments

    Model 109SS Temperature Probe The ratio of measured voltage (Vs) to excitation voltage (Vx) is related to thermistor resistance (Rs) and the 24.9 kΩ bridge resistor as described in the following equations: Vs/Vx = 24900 Ω / (Rs + 24900 Ω) Solving for Rs: Rs + 24900 Ω...

  • Page 18: Troubleshooting And Maintenance

    Periodically check cabling for signs of damage and possible moisture intrusion. Calibration Calibration of the 109SS probe is not necessary unless the application requires removal of the thermistor interchangeability offset described in Section 6, Specifications.
