Barksdale D2X-A80SS-UL Mechanical Pressure Switch

The Barksdale D2X-A80SS-UL is an explosion‑proof diaphragm pressure switch with dual setpoints, designed for hazardous locations and offering precise control in the 0.5 to 80 psi range. The housed, SPDT dual‑setpoint unit uses a metal diaphragm with welded wetted parts for robust reliability in tough environments, and it mounts via a 1/4" NPT female connection. It carries UL and CSA approvals with Ex ia and Ex d options for intrinsically safe and flame‑proof service, and electrical ratings include 125–250 VAC (with variants up to 480 VAC) to suit a wide range of control circuits. Construction emphasizes reliability in hazardous environments, with a temperature range from -40°C to +75°C and a maximum switching rate of about 20 cycles per minute; repeatability is ±1% of full scale at constant temperature. The D2X family is widely used in petrochemical and process industries for pressure control of safety systems, process valves, and pumps, offering a compact, dual‑setpoint diaphragm switch that delivers precise signaling while withstanding demanding installations.
