This differential pressure gauge with contacts integrates a mechanical contact mechanism into the differential pressure indicator. Utilizing a combination of carefully selected Bourdon tubes, diaphragms, bellows, and micro switches, our unique mechanism detects and indicates the pressure difference between various points, opening and closing the micro switch when the differential pressure reaches the preset value. Compared to the pointer contact type, this gauge provides more accurate indications and offers excellent performance for alarm control due to its large contact capacity.
