Probe Thermostats

Probe thermostats use a bi-metallic snap action switch that is potted in a stainless steel, brass or other housing material on request. The probes are used to sense air or fluid and are mounted via an NPT thread or a flange. These sensors are typically used as an over temperature protection device and can be designed to either open or close an electrical circuit at a pre-set temperature. Probes can be used in control applications with designs that have tight hysteresis.

Standard Features:

  • *Brass or 304 SS Housing – Various Housings in Stock
  • *Temperature Range 0-175 C (higher and lower temperatures on request)
  • *Max 16 Amps/250 VAC, Min 100 mA DC
  • * Tolerance to +/- 1 C Depending on Temperature
  • * Wire Leads with Quick Connect Option
