Ashcroft B724B Pressure Switch

Ashcroft B724B is a B-Series B7 NEMA 7/9 explosion-proof pressure switch designed for hazardous environments, offering rugged, field-serviceable control for pressure sensing in process industries where shutdown or alarm function is required. As part of the B7 family, the B724B provides adjustable setpoints from 15% to 100% of the configured range, with either fixed or limited adjustable deadband, and it supports a selection of diaphragms (Buna N, Viton, Teflon, 316L, Monel) to suit media compatibility. The unit carries a NEMA 7/9 explosion-proof enclosure and various hazardous-area certifications, including UL and CSA listings with ATEX and IECEx approvals, making it suitable for refineries, chemical plants, water treatment, and other demanding installations. Electrical configuration and exact pressure range are defined by the ordering code and nameplate; this variant lists 15A at 125/250/480 VAC and a 100 range designation with a 20 psi proof pressure, reflecting its suitability for higher-pressure control applications in hazardous settings.
