TSA01 Series are economic, factory preset temperature
switches that feature a one-piece thermowell design which
houses a SPST bimetallic switch. The one-piece design
offers integrity against leaks vs. other welded designs.
Probe lengths are limited to 1” (25mm). Available process
fittings are 1/2” and 3/4” NPT.

A bi-metal disk, mounted in the tip of the probe, provides
fast thermal response and rapid positive contact action
when the preset temperature is reached. It resets
automatically on cooling. Switching action is SPST, wired
normally open or normally closed. Some can be used as
controlling thermostats which cycle open and close more
rapidly to maintain temperature level.
