These Pressure switches cover all industrial applications thanks to their wide range of pressures and contact materials.
A sealing diaphragm seal is used to provide an accurate measurement value (0.2% repeatability) thus ensuring high performance.

The series of RIBW pressure switches with diaphragm / piston coupling with self-locking device is weatherproof thanks to the IP66 protection, copper-free aluminum alloy case with epoxy paint or completely in SS316L.

Adjustment range: is the pressure range within which the instrument can be adjusted (contact switching)
Differential: it is the difference between the contact closing pressure and the contact opening pressure
Admissible overpressure: maximum permanent or instantaneous pressure that the unit can withstand
Max. Test pressure: the highest pressure to which the unit can be subjected, for example during the system leakage check. This pressure does not have to constitute the constant pressure of the system.
Min. Burst pressure: it is the pressure that the sensitive element can withstand without leakage.
