The TM series of temperature switches is a completely electronic instrument that detects the increase or decrease of temperature.

These switches are used in industrial applications including pipelines and tanks. The RTD sensor provides an extremely reliable and repeatable device at a very cost effective price. 

The TM Series has a general-purpose enclosure while the TX Series has and explosion proof NEMA 4X enclosure.

316L stainless steel is standard for all wetted surfaces, exotic alloys such as Hastelloy® C276 are available upon request. A relay output is standard with options for dual separately adjustable set-points.

Remote mounted electronics are available for process temperatures to 900° F.
