Pressure Ranges to 8000 psi (551.6 bar)
Bourdon Tube Pressure Switches have extremely high sensitivity and great repeatability. Hermetically sealed mercury switch is available. Applications include compressors and pump control.
Features
-
Visible calibrated dial provides an easy and fast check without having to open device causing dangerous conditions to operators
-
On/off indication (except hermetically sealed snap switch models) gives operator clear indication of state of switched equipment that could be located in another location
-
Adjustable or fixed deadband supports control applications by reducing equipment wear-out by unnecessary recycling
-
External switch setpoint adjustments reduces set-up time
-
Pressure ranges of full vacuum to 8000 psig gives application designers the ability to specify standard equipment, simplifying install and training, and reducing servicing costs
-
UL listed, CSA approved many models FM approved to support rigorous process applications and regulations
-
General purpose, weatherproof or explosion-proof enclosures for a variety of indoor or outdoor environments meeting the needs of multiple applications and uses
