Stainless Steel Thermistor Probe
TSSP‑1TM is a stainless steel thermistor probe used to measure soil temperature, liquid temperature, or surface temperature. The sensing element is a swaged stainless steel shell.
Dyacon thermistor probe TSSP‑1TM is a precision sensing element in a robust, waterproof package.
Unlike other stainless steel probes, TSSP‑1 is swaged, with the stainless steel enclosure formed around the double-potted sensor element. This construction forms a very durable probe assembly that will not crack or separate in cyclical temperature or vibration environments.
TSSP‑1 is suitable for soil and liquid submersion measurements. The thermistor can be used for continuous cyclic operation at -40°C to 105°C (-40°F to 221°F) and is interchangeable to within +/- 0.10°C. This facilitates easy setup, maintenance, and upgrade for most applications.
An included cable length of 6 m (20 ft) minimizes the need for cuts and splices. The TSSP‑1 kit also includes installation instructions for the Dyacon control module.
TSSP‑1 is double potted with thermally conductive epoxy and swaged in a stainless steel probe. The swaged enclosure increases the cable strain relief and sensor sealing. The sensor is designed to neither crack nor come loose from the stainless steel tip, even in high temperature cycling environments.
An interchangeability value of 0.1°C ensures that TSSP‑1 thermistors are field replaceable without further calibration.
Once TSSP‑1 is installed in a Dyacon Control Module, the user can simply enable the thermistor configuration through the menu, and probe measurements will be included in the condition reports.
