The Mechanical 130-250F Oil Sealed Temperature Murphygage 2" with 25 Ft Capillary 20TG-OS-250-25-1/2 by Murphy 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. This is a gage-only model without contacts.
Applications: Industrial engines and equipment in Oil Field, Marine, Irrigation, Construction and Trucking industries. Monitoring Engine Coolant, Crankcase Oil and Transmission Oil
