Applications
Contact Gauges are ideal in the applications which demands measurement and control of pressure by switching electrical contacts ON and OFF. This eliminates the need of separate switches for pumps and motors which gives audio or visual alarms. The small adjustable magnet mounted in the contact assembly, attracts the contact arm just before the set pressure value which prevent the common problem of arcing and burning of contact pins.
