The WIKA high-quality MA diaphragm pressure switch is developed for safety-critical applications. The high quality of the WIKA MA diaphragm pressure switch is following ISO 9001, which 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 materials are from stainless steel as a standard.

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.

For applications with special requirements on the wetted parts, versions with materials from PTFE, Monel or Hastelloy are available.
By using a diaphragm measuring system, the model MA pressure switch is extremely robust and guarantees optimal operating characteristics.
For setting ranges from 4 … 40 bar a piston replaces or completes the diaphragm as a measuring element. The wetted parts of this variant from stainless steel are particularly suited for liquid media.
