The Murphy 130-250F Direct Mount Temperature Swichgage 2 inch 20SD-250-1/4 is a diaphragm-actuated, temperature-indicating gage with a 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 Swichgage features 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. Contacts are isolated through ground. This gage has a self-cleaning motion to enhance electrical continuity. This model has no capillary tube.
