Mechanical 130-220F Temperature Murphygage 2 in. w/ 4 Ft Capillary - Without Contact - 20TG-OS-220-4-1/2

The Mechanical 130-220F Temperature Murphygage 2" with 4 Ft Capillary 20TG-OS-220-4-1/2 is diaphragm-actuated, temperature-indicating gage without contacts/switch. The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument.  This vapor 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 the diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading.

Applications: Industrial engines and equipment in Oil Field, Marine, Irrigation Construction and Trucking industries. Monitoring Engine Coolant, Crankcase Oil and Transmission Oil.
