Differential pressure relays

Differential pressure switches detect overpressure, vacuum or differential pressure. The switching pressure setpoint can be adjusted by means of a scaled calibrated knob. A typical application is to detect a clogged air filter or to generate an alert if the air flow drops below a critical level.
