Differential Pressure Sensors and Monitoring for HVAC Systems

The differential pressure switch follows the pressure between the two places. If the pressure reaches a particular point, then the internal diaphragm in the switch will make contact after deflecting. This contact will either make or break a circuit. The change in the circuit will trigger an alarm that tells the user that the pressure has changed.
