The Murphy Swichgage 300-440°F Temperature Gauge 20T-440-10-1/2 is a diaphragm-actuated, temperature-indicating gage 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 10 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 gauge 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.
