Pressure switches

By Mary C. Gannon,
Senior Associate Editor

Weatherproof pressure switches with standard wetted parts are suitable for air, oil, water, and non-corrosive fluids. They are rated for pressures from 30-in. Hg vacuum to 7000 psi. Pressure sensing element is a force-balanced piston-actuated assembly and sealed by a flexible diaphragm and static O-ring. Features include high-cycle rate tolerance, self-locking adjustment, high over-range and proof pressures, narrow deadband and high resistance to corrosive and hostile environments.
