20DP, 25DP, A20DP, A25DP
Differential Pressure Swichgage® for Filter
Restriction
The 20DP and A20DP series (2 inch /
51 mm dial) and the 25DP and
A25DP series (2½ inch/64 mm dial) SWICHGAGE® models are
diaphragm-actuated, differential pressure indicating gauges with
a built-in electrical switch. The Swichgage® indicates the pressure difference between 2 inlet ports, and provides a closing contact when the user-set limit is exceeded.
These gauges are intended to monitor for oil, fuel or water filter restriction: they can reduce the risk of dangerously high pressure which may rupture the filter, resulting in contaminants entering the system; they can also trigger automatic flushing (backwash) in irrigation systems.
Features:
- Monitors oil, fuel and water filters
- Combination indicating gauge and user-set limit switch
- Actuates alarm, shutdown or backwash when filter becomes clogged
- Signals coolant loss or aeration on engine water pump
- Metal case, ground return (20DP/25DP) or
polycarbonate case, insulated return (A20DP/A25DP) - Available in dual (PSID/kPa) or single (Bar) scales
