The 25DP and A25DP Series (2-1/2 in. /64 mm dial) Swichgage instruments are diaphragm-actuated, differential pressure-indicating gauges with a built-in electrical switch. This switch is used for tripping alarms and/or shutting down equipment. The gauges 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 25DP series mechanism is enclosed in a steel case coated to resist corrosion. The A25DP series has a polycarbonate case sealed from the environment. Both feature a polycarbonate, break-resistant lens to help protect the instruments.

The gauge 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.

Early filter changes cost money and increase the risk of contaminants entering the system. A filter restriction Swichgage instrument lets you know when to change the filter and maintain peak efficiency.
