Pressure

Pressure Switches

Pressure, vacuum and differential-pressure switches, including explosion-proof models.

Pressure switches provide alarm and trip functions without a control system in the loop. The range covers hermetically sealed and explosion-proof process switches for hazardous areas through to HVAC differential-pressure and airflow switches.
