Dwyer DA-7031-153-6 Bourdon Tube Pressure Switch, 5–100 Psig, SPDT, Brass

The Dwyer DA-7031-153-6 is a reliable Bourdon tube pressure switch engineered for demanding HVAC and industrial pressure monitoring applications. With a wide 5 to 100 Psig operating range and a 13.5 Psig adjustable deadband, this switch delivers precise, repeatable switching performance across a broad spectrum of system pressures.

Built with a durable brass Bourdon tube, the DA-7031-153-6 resists corrosion and withstands the rigors of everyday mechanical system environments. The general purpose enclosure protects internal components while keeping installation straightforward. A 1/4″ Male NPT process connection ensures compatibility with standard pipe fittings, and the vertical mounting orientation simplifies integration into existing piping configurations.

The single-pole, double-throw (SPDT) output provides flexible wiring options for both normally open and normally closed circuit configurations, making this switch adaptable to a wide variety of control and safety applications. Rated at 10 amps, it is capable of directly switching loads without the need for additional relays in most standard control circuits.
