Temperature Switches

The Whitman Controls TP Series Economical Stainless Steel Temperature Probe Switches are a creep action thermostat/thermal protector switch providing almost no differential between opening and closing temperatures. The switch is designed for use from 50˚F to 250˚F in 25˚F increments with a +/-5˚F tolerance.

Special temperature ranges and configurations are available for OEM customers. The probe length is .625″ standard, but lengths from 0.0″ to 3″ (or longer) can be offered on a custom basis.

These switches are available wired Normally Closed or Normally Open on increasing temperature. The stainless steel wetted material affords use in any number of processes from medical to food processing, to oil baths and refrigeration.

These switches come standard with 1/2″ NPT Male threads, and additional fittings including 1/4″ NPT, 3/8″ NPT, 3/4″ NPT, 1/2″ BSPP and many others are available upon request. This is a highly customizable unit with use across a number of OEM applications.

Please reach out to our engineering team if you have a custom request and we would be happy to design a unit to meet your exact specifications.
