Industrial D2H-A150SS Dual Setpoint Pressure Switch

Industrial D2H-A150SS Dual Setpoint Pressure Switch from Barksdale is a housed diaphragm switch that provides two independently adjustable setpoints in a single, rugged enclosure for reliable pressure control in industrial systems. It measures a pressure range of 1.5 to 150 psi and uses a 1/4" NPT female pressure connection to attach to standard piping, with SPDT dual-setpoint contacts that switch control circuits at two defined pressures. The unit is rated for up to 10 A at 125/250 VAC and 3 A at 480 VAC, enabling direct interfacing with relays, controllers, and safety interlocks across typical automation circuits, and it comes in a durable anodized aluminum housing with a NEMA 4 enclosure designed for harsh environments. A tamper‑resistant cover protects the setpoint adjustment screws, and the housed D2H model is designed for reliable operation in industrial settings such as pneumatic controls, process monitoring, and safety shutoff sequences in manufacturing, packaging lines, and fluid-handling systems.
