The Murphy 32-160F Mechanical Temperature Swichgage Field Adjustable 2.5" with 12 Ft Capillary and Snap-Acting Switch A25TEF-160-12-1/2 is a diaphragm-actuated, temperature-indicating gage with built-in electrical switch for tripping alarms and/or shutdown devices. This rugged, built-to-last instrument is fully sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel, and O-ring seals. This vapor actuated gauge features a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against a diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading. This A25TEF-160-12-1/2 also features an internal SPDT snap-switch, instead of the single pole/pointer contact(s). When the switch closes on rising temperature, it becomes Set. As temperature decreases the switch Resets.

The gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contact(s) are isolated from ground. They have self-cleaning motion to enhance electrical continuity. Applications for A25 series temperature swichgage instruments include: engines and equipment in oil field, marine, irrigation, construction and trucking industries. Monitoring engine coolant temperature, crankcase oil and transmission oil.
