The Mechanical 130-250F Temperature Murphygage 2.5" with 4 Ft Capillary A25TG-250-4-1/2 by Murphy is diaphragm-actuated, temperature-indicating gage without contacts/switch. 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.

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.
