A20-A25P SERIES PRESSURE SWICHGAGE
A20/A25P-SWICHGAGE AND MURPHYGAGE INSTRUMENTS

Swichgage instruments are high-quality diaphragm-actuated, dial gauges for various with built-in electrical switches. 

Used for tripping alarms and/or shutdown devices, the pointer acts as both an indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. 

Contacts have a self-cleaning motion to ensure electrical continuity. 

More compact, gauge-only models without contacts (known as Murphygage instruments) are also available.

The A20 Series (2 inch/51 mm dial) and the A25 Series (2-1/2 inch/64 mm dial) Swichgage instruments are diaphragm-actuated, pressure-indicating gages with built-in electrical switches for tripping alarms and/or shut-down devices. 

Ranges are available from 0-15 psi (103 kPa) [1.0 bar] through 0-400 psi (2.8 MPa) [28 bar].

Swichgage® instruments are made in the USA and have protected engines and equipment in applications such as oil and gas, marine, irrigation, construction and trucking applications to monitor engine lube pressure, water pump pressure, hydraulic pressure, air pressure, and others for more than 80 years.
