Wika Model BWX Stainless Steel Pressure Switch

By using a Bourdon tube measuring system, the model BWX pressure switch is extremely robust and guarantees optimal operating characteristics and the highest measuring performances with repeatability lower than 0.5 % of span.

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. 

For applications with special requirements on the wetted parts, a version with Monel is available.
