Schneider Electric SE 9012ADW3 Pressure Switch

Schneider Electric's Square D 9012ADW3 pressure switch is a high‑pressure, piston‑actuated device in the 9012 ADW family designed for differential‑pressure monitoring in industrial systems. It offers a setpoint range from 135 to 1000 psi, with a 35 to 135 psi differential, and uses SPDT contacts (1 normally open and 1 normally closed) to switch two circuits. The enclosure is IP65 rated for protected operation in harsh environments, and the 9012ADW3 is commonly used to monitor water and hydraulic oil pressures in hydraulic or pumping applications. Setpoints are factory‑set and indicated on the switch housing, with the ADW3 configuration describing this specific pressure switch variant.
