Differential Pressure Switch

The Delta-Pro Models 932413 and 932414 NEMA 4 differential pressure switches offer a unique blend of small size, excellent performance, environmental protection. They can be used with liquids or gases.
The precision snap-acting switch and sensitive opposing diaphragms combine to provide a narrow deadband and repeatability of approximately 1% of span. Mechanical contact life is 10 million cycles, and actual switch life can be very long with typical pilot duty loads.  NEMA 4 enclosure is small, yet it can still accommodate a 1/2" NPT conduit connection and terminal block wiring.
The multiturn adjustment screw is externally accessible for convenience and excellent resolution.
