Pressure Switch | WIKA MW

These high-quality pressure switches have been developed especially for safety-critical applications. The high quality of the products and manufacturing in accordance with ISO 9001 ensure 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 materials are from stainless steel as a standard.

In order to ensure as flexible operation as possible, the pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly. For lower switching power 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 MW pressure switch is extremely robust and guarantees optimal operating characteristics.

For applications with special requirements on the wetted parts, versions with materials from PTFE, Monel or Hastelloy are available.
