Humphrey 25-DP-5 Differential Pressure Switch is a differential pressure sensing device that detects pressure differences between two points and provides a discrete electrical output when a difference is detected. The model designation 25-DP-5 identifies this specific Humphrey switch, used to indicate changes in monitored pressure and drive downstream control circuits. This DP switch serves as a direct interface for monitoring differential pressure and triggering responses in systems that rely on a binary, on/off signal based on pressure conditions.
