The Murphy 0-30 PSI Differential Pressure Swichgage 2.5 inch with Knob Adjusting Face Contact A25DP-K-30 is a diaphragm-actuated differential pressure-indicating gage with a built in electrical switch. This switch is used for tripping alarms and/or shutting down equipment. The swichgage A25DP-K-30 is intended to monitor and indicate oil, fuel or water filter restriction and can reduce the risk of dangerously high pressure which may rupture the filter, resulting in contaminants entering the system. This model has a polycarbonate case and are sealed from the environment. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument.
The gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts have self-cleaning motion to ensure electrical continuity.
