Gas compensation ensures greater precision of the set point.
Suitable for various indoor and outdoor installation requirements
Micro switch enables normally open contacts and normally closed contacts freely switch to each other.
Up to four switch contacts can provide overpressure alarm, dual alarm or double locking, and many other solutions, which ensure secure and more reliable monitoring
High resistance to shock
Without oil, no risk of leakage
Closed contacts normally do not trigger false vibratory alarms
