This sensor is used to measure water temperature of heated or chilled water and other liquids in mechanical systems.The sensor includes a brass well which allows the probe to be removed from the pipe without draining the system and protects the probe.There are four thermistor based models, and one RTD version to provide compatibility with the majority of DDC systems. The sensors are accurate enough that calibration is not usually required.

Sensor Property Specification:

Thermistor Accuracy +/-0.2C

Platinum RTD Accuracy +/-o.4C

Thermistor range -70C to 150C

Probe Material Stainless

Cable Properties FT4, 80C, 600V

Construction

The sensor probe is made to industrial standards, the stainless steel probe is welded, ground down and finally pressure tested. The probe assembly is baked and epoxy sealed to provide long term protection from moisture. The probe is spring loaded to ensure thermal contact with the bottom of the well. The thermistors are accurate to 0.2C while the platinum RTD is accurate to 0.5C The well is made from machined brass, and fits a standard ½” NPT fitting. The sensor housing is a galvanized electrical box.
