The Murphy 160-320F Mechanical Temperature Swichgage with 4 Ft Capillary 20T-320-4-1/2 is a diaphragm-actuated, temperature-indicating gauge with built-in electrical switch for tripping alarms and/or shutdown devices. The gauge mechanism is enclosed in a steel case coated to resist corrosion and it has a 16 foot capillary length with a standard 1/2-14 NPT thread. 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.

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 grounded through the Swichgage case. They have self-cleaning motion to enhance electrical continuity.
