These high-quality diaphragm pressure switches have been produced especially for safety-critical purposes. The great quality of the products and manufacturing under ISO 9001 ensure reliable monitoring of your plant. In production, the switches are tracked by quality assurance software at every step, and finally, they are 100 % tested.

All wetted elements are from stainless steel as a standard. To assure as flexible operation as possible, the diaphragm pressure switch are arranged with micro switches, which enable the switching of an electrical charge of up to AC 250 V, 20 A directly.

For lower switching power evaluations, such as for PLC applications, argon gas-filled micro switches with gold-plated connections can be chosen as an option. By using a diaphragm checking system, the model MW diaphragm pressure switch is notably robust and guarantees optimal operating characteristics. For applications with special conditions on the wetted parts, versions with materials from PTFE, Monel or Hastelloy are possible.


For setting series from 4 ... 40 bar a piston replaces or performs the diaphragm as a measuring element. The wetted aspects of this variant from stainless steel are especially suited for liquid media.
