BARKSDALE DPD2T-A150SS Door Interlock Safety Switch

The Barksdale DPD2T-A150SS is a dual‑setpoint diaphragm differential pressure switch designed to monitor pressure differentials across filters, valves, and other process equipment in rugged environments. It covers a differential range of 1.5 to 150 psi (A150SS) with external adjustment screws for both setpoints, and provides two SPDT contacts rated up to 10 A at 125/250 VAC, 3 A at 480 VAC, and 0.5 A at 24 VDC. The unit features a stainless steel diaphragm with Viton seals, a stainless steel body, and 1/8" FNPT stainless pressure connections, plus a 1/2" FNPT electrical connection, all housed in a NEMA 4 enclosure for weather- and washdown‑resistant operation. Configurable as the dual‑setpoint DPD2T in the DPD1T/DPD2T family, it supports optional enclosures and limit switch configurations (for example, FX options with a 6‑contact terminal block; 3SS hermetically sealed limit switch options available for hazardous locations).
