Description
The PCS compact pressure switch for the process industry from WIKA is used for pressure measurement of gaseous and liquid media.
Pressure switches have been developed specifically for safety-critical applications with limited space.
High product quality and ISO 9001 manufacturing ensure reliable control of your plant. In production, the switches are tracked every step of the way by quality assurance software and then 100% tested.
All wetted parts are stainless steel as standard. The switch housing is available in aluminium alloy or stainless steel.
To set the set point, simply open the access cover. This access can be sealed as an option.
Access to the electrical connection block shall be protected by a screw cover secured by a screw lock against unauthorised tampering.
The pressure switches are equipped with a single micro-switch that allows direct switching of electrical loads up to 250 V, 15 A. For lower switching power ratings, for example for PLC applications, argon-filled micro-switches with gold-plated contacts can be selected as an option. For two separate circuits, the switches are also available in a DPDT (double pole double throw) version. Using a diaphragm with an antagonistic spring as the sensing element, the PCS model pressure switch is extremely robust and provides optimum performance.
At high setting ranges, the piston replaces or complements the diaphragm as a measuring element. The piston sensor element is designed for the specific needs of liquid media.

Areas of application, PCS applications
- pressure monitoring and process control
- for measuring points with limited space, e.g. control panels
- for gaseous and liquid, aggressive, highly viscous or contaminated media, also in aggressive environments
- safety critical applications in general process instrumentation, in particular in the chemical and petrochemical industries, oil and gas, power generation, incl. nuclear power plants, water/wastewater industry, mining
