FDA – Differential Pressure Switch

The FDA Series compact design enables them to be mounted in tight spaces. The switches use a piston/diaphragm design which incorporates the high proof pressure of piston technology with the sensitivity of a diaphragm design. The FDA series switches may be field or factory adjusted via a hex screw inside the low port, protecting them against unauthorized tampering.
