The WIKA PCS Pressure Switch is a compact and high-performance mechanical pressure
switch designed for pressure monitoring and control in critical industrial process applications.
Manufactured by WIKA, the PCS series is engineered specifically for safety-critical
environments requiring reliable switching performance, rugged construction, and compact
installation dimensions.
The pressure switch operates using a diaphragm or piston sensing element combined with
precision microswitch technology to activate electrical contacts when the preset pressure point
is reached. Designed for demanding process industries, the PCS pressure switch supports
pressure ranges from vacuum up to 1,000 bar and provides dependable switching for liquids,
gases, viscous, and contaminated media.
Its robust enclosure is available in aluminium alloy or stainless steel with IP66 / NEMA 4X
protection, ensuring reliable operation in harsh industrial and outdoor environments. The WIKA
PCS pressure switch is widely used in oil & gas, petrochemical, power generation, water
treatment, mining, and industrial automation systems where accurate and dependable pressure
switching is essential.
