Barksdale DPDIT-A3 Differential Pressure Switch

The Barksdale DPDIT-A3 Differential Pressure Switch is an industrial‑grade device designed to monitor the differential pressure across a system and provide an electrical output within a 0.03–3 psi range. Differential pressure switches sense pressure on two ports and switch a circuit when the differential reaches their operating point, enabling automation and safety interlocks in process control. The DPDIT-A3 is rated for 125/250/480 VAC operation, allowing direct integration with common power supplies and control panels in demanding environments. As part of Barksdale’s family of differential pressure switches, the DPDIT-A3 is designed for reliable operation under varying process conditions where accurate monitoring of small pressure differentials is essential.
