OMEGA’s TSW Series adjustable temperature switch
is perfect for applications that require an economical
solution to temperature control. The stainless steel
stem of the TSW Series switch is sealed and filled
with a gas that expands as process temperature rises.
A membrane within the switch body mechanically
causes closure of a 5 A Form “C” relay.
The 9.7 mm (0.38") diameter of the probe is designed
to mate with OMEGA’s standard 385 Series
thermowells for your most rugged applications.
Please see Section B.
