Main applications :
Its applications are in the detection of the suction of water pumps, filter clogging of vacuum cleaners, pumps for vacuum packaging devices, checking of the presence of vacuum in professional equipment.
Its high electrical rating allows it to be used without power relay in the control of motors or heating elements etc.
