The Murphy 0-15 PSI Mechanical Differential Pressure Swichgage 20DP-15 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. Gauge 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. The 20DP mechanism is enclosed in a steel case coated to resist corrosion and it features a polycarbonate, break-resistant lens and a polished, stainless steel bezel to 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.

- 2 inch/51 mm dial
