Differential Pressure Switch D56M Series

This low pressure product provides performance usually associated with a larger/bulkier unit. A 2.5" dia., 2" height and low 6 oz weight allows its use in many airborne and military weapons systems where space and weight are critical. The sensing diaphragm is polymide, which provides long life and can tolerate differential over pressures to 20 PSID. Silicone rubber can be substituted for extreme temperatures. Applications include filters as well as airflow control plenums. Double containment diaphragm models are available for NBC (Nuclear, Biological, Chemical) systems.
