05701766 Murphy Differential Pressure Swichgage Model A20DP-K-2B

The 20DP and A20DP Series (2 inch/51 mm dial) and the 25DP and A25DP Series (2-1/2 inch/64 mm dial) Swichgage instruments are diaphragm-actuated, differential pressure-indicating gages with a built-in electrical switch. This switch is used for tripping alarms and/or shutting down equipment. These gages are 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 A20DP and A25DP series have a polycarbonate case and are sealed from the environment. All feature a polycarbonate, breakresistant lens and a polished, stainless steel bezel to help protect these rugged, built-to-last instruments. 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.

This product may vary on delivery times, as factories do not guarantee production due to lack of raw materials.
