The Murphy Temperature Swichgage A25T-HL-250-8-1/2 is a diaphragm-actuated, temperature-indicating gage, with built-in electrical switch for tripping alarms and/or shutdown devices. 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 is isolated from ground. it has a self-cleaning motion to enhance electrical continuity.

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 seal. This vapor/pressure actuated gage 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.

Applications for this instrument includes: engines and equipment in the oil field, marine, irrigation, construction and trucking industries, monitoring engine coolant temperature, crankcase oil, transmission oil.
