PSW

differential pressure switch

These adjustable high sensitive differential pressure switches are used for monitoring overpressure, vacuum and differential pressure of air or other non-combustible, non-agressive gases. he switching set-point can be adjusted by means of a calibrated knob. The switching differential DP can be adjusted with a screw driver. Possible applications are: Air filters and fan monitoring, Overheating protection for electric batteries or electric heating elements, Controlling air- and fire-protection dampers, Monitoring air flows, and more...
