Industrial Temperature Gauge

The Murphy 160-320F Cylinder Head Temperature Swichgage with 6 Ft Capillary and 2 inch/51 mm dial 20TH-320-6-M10 is a diaphragm-actuated, temperature-indicating gage with built-in electrical switch for tripping alarms and/or shutdown devices. 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.

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. It has a self-cleaning motion to enhance electrical continuity.
