Overview

Temperature Sensor (-40 to +70C)

The 109SS is a rugged, accurate probe that measures soil or water temperature from -40° to +70°C. The 109SS consists of a thermistor encased in a sheath made from grade 316L stainless steel. The rugged stainless-steel sheath protects the thermistor, allowing you to bury or submerge the 109SS in harsh, corrosive environments. This probe also has a fast time response, and it can be easily interfaced with our data loggers.

Key Advantages

Rugged, Accurate, Versatile
Can be used in a variety of applications

Technical Description

The 109SS thermistor can survive temperatures up to 100°C, but the overmolded joint and cable should not be exposed to temperatures hotter than +70°C.

Water Temperature

The sensor can be submerged to 46 m (150 ft) or 63 psi. Please note that the 109SS is not weighted. Therefore, the installer should either add a weighting system or secure the sensor to a fixed, submerged object, such as a piling.

Soil Temperature

The 109SS is suitable for shallow burial only. Placement of the sensor’s cable inside a rugged conduit may be advisable for long cable runs—especially in locations subject to digging, mowing, traffic, use of power tools, or lightning strikes.

Benefits

  • Designed for harsh, corrosive environments
  • Fast response time
  • Wide temperature measurement range
  • Easy to install or remove
  • Compatible with most of our current and retired data loggers

Accuracy
Note: 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.
