WIKA | Pressure Switch | BA
The WIKA BA Pressure Switch is a high-performance bourdon tube pressure switch designed
for reliable pressure monitoring and control in safety-critical industrial applications.
Manufactured by WIKA, the BA series is engineered for demanding process industries requiring
robust construction, high switching reliability, and long operational life.
The pressure switch utilizes a bourdon tube measuring system combined with precision
microswitch technology to activate electrical contacts when the preset pressure point is
reached. Its rugged stainless steel construction and flameproof Ex d enclosure ensure
dependable operation in harsh industrial and hazardous environments involving liquids, gases,
and aggressive media.
Designed specifically for critical process monitoring applications, the WIKA BA pressure switch
offers high switching power, excellent repeatability, and optional SIL 2 / SIL 3 functional safety
compliance. The switch is widely used in chemical plants, oil & gas facilities, power generation
systems, mining operations, and water treatment industries where reliable pressure switching
and process protection are essential.
