Sirco Ex4000 Pressure Switch is a compact, ATEX-certified control designed for hazardous-area service, and is part of Sirco’s rugged 4000 Series that offers flexible protection levels and output configurations. Built with gravity-cast housings to minimize set-point drift and enhance reliability, the Ex4000 provides a 250 V, 5 A electrical switching capability and a selectable pressure range of 10–100 psi (approximately 0.7–7 bar), making it suitable for monitoring pneumatic and hydraulic lines in explosion-risk environments. The series is designed to accommodate different control schemes with a choice of electrical and pneumatic outputs and multiple approvals, enabling straightforward integration into existing safety systems while meeting applicable hazardous-area standards. Verified Baseefa/ SGS documentation confirms the Ex4000’s ATEX approval within the Sirco Ex4000 line, underscoring its suitability for use where flammable vapors or gases may be present. Typical applications include safety interlocks, shutdown signals, and automated control in industries such as chemical processing, oil and gas, and other facilities that require explosion-protected pressure sensing and reliable switch action in demanding conditions.
