These high-quality pressure switches have been specifically developed for safety-critical applications. High quality and product manufacturing to ISO 9001:2000 ensures reliable monitoring of your plant.

In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.

All wetted parts materials are from stainless steel as standard. Each switch family is available in IP 65, Ex-ia or Ex-d versions (Ex-d see model MAH, data sheet PV 31.15).

In order to ensure as flexible operation as possible, the pressure switches are equipped with micro switches, which make it possible to switch an electrical load of up to 15 A / AC 220 V directly.

For smaller contact ratings, such as for PLC applications, argon gas filled micro switches with gold-plated contacts can be selected as an option.

By using a diaphragm measuring system, the model MWH pressure switch is extremely robust and guarantees optimal operating characteristics at very high pressures.
