UE 100 Series Differential Pressure Switch

UE 100 Series Differential Pressure  SWITCH

The 100 Series is a cost-effective pressure and temperature switch

for process plants and OEM equipment. The rugged, one piece

enclosure features a slanted cover for wiring accessibility.

A wide variety of microswitch and process-connection options

make this versatile series ideal for applications requiring a rugged

weather-proof mechanical switch.

Typical applications that utilize the 100 Series are heat tracing,

freeze protection, processing equipment (pumps, compressors),

inputs for annunciator panels, and fire suppression systems.
