• Two instruments in one with an accurate indicating gage and adjustable p.s.i.d. limit switch reduces inventory and installation time.
• Adjustable contact lets you set the monitoring range of the gage. The contact is tamper proof and can be set only with a 1/16 Allen-head wrench.

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