Description

OMEGA’s TSW series adjustable temperature switch is perfect for applications which 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 Amp 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. See Section B of the OMEGA Complete Temperature Measurement and Control Handbook and Encyclopedia® for thermowell selection.
