Product Description

Murphy By Enovation - A20PE-OS-150: 2" Pressure Swichgage; Internal Snap-Acting SPDT Switch; Oil Sealed; 0-150 Psi (05704315)

Swichgage instruments are built 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 coolant, crankcase oil, transmission oil and others for more than 80 years.

The A20PE Swichgage is CSA listed for non-hazardous areas, and it features internal snap-acting SPDT switches, instead of the single pole/pointer contacts, for three wire control and can be wired to make or to break a circuit. When the switch closes on falling pressure, it becomes set, as pressure rises the switch resets.
