Differential pressure switch
Description
Differential pressure switches compare the pressure in 2 chambers and switch a directional control valve if the pressure exceeds or falls below a preset value.
If the differential pressure to be monitored returns to the standard range, the monitor switches back again.
They are used, for example, to monitor contamination on filters or to monitor the movement of valves if the differential pressure is too high or too low.
