EPS40EXP HONEYWELL

Product Overview

The System Sensor by Honeywell EPS40EXP is an industrial-grade, explosion-proof supervisory pressure switch engineered for hazardous-location fire protection systems. It is primarily utilized to monitor pressure variations in dry-pipe fire sprinkler systems, pre-action systems, and dedicated pressure tanks. The device features a field-adjustable sensitivity range from 10 to 100 PSI and uses a dual-switch configuration to flag low or high pressure conditions. Housed in a heavy-duty NEMA 4 rated cast aluminum enclosure, the EPS40EXP is explicitly certified to prevent the ignition of hazardous external atmospheres, making it an essential component for chemical plants, refineries, grain elevators, and industrial manufacturing sites.
