WM12040 differential pressure switch is a kind of delicate, flexible and convenient differential pressure switch. It is equipped with a mechanical mechanism. When the differential pressure rises or falls, the corresponding mechanism produces stretch or contraction displacement, and then push the switch action through the lever, cut off or switch on the control loop. WM12040 differential pressure switch has exquisite window to display the actual pressure value, and has the adjustment knob to adjust the differential pressure control value.
