Wika Model PCS Compact Pressure Switch

By using a diaphragm element with antagonist spring as sensor element, the model PCS pressure switch is extremely robust and guarantees optimal operating characteristics. For safety applications, the pressure switch is optionally available in a SIL 2 qualified or a SIL 3 qualified version.

Depending on the application, the appropriate variant for the contact version and the electrical connection can be selected; e.g., hermetically sealed micro switches are suitable for corrosive ambient conditions and DPDT contact versions for two separate circuits.
