20T-320-6-1/2 Temperature Swichgage (10702082)

20T-320-6-1/2: 2" Temperature Swichgage; 160-320¡ F. temp range; 6 ft. capillary length (10702082)

This very popular design Features a diaphragm-actuated, temperature-indicating gage, with a built-in electrical switch for tripping alarms and/or shutdown devices.

This model has a 6-foot capillary length with a standard 1/2-14 NPT threading, and a temperature range from 160-320¿F (71-160¿C).

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. Inside the 20T-320-6-1/2, 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.

This gage has a self-cleaning motion to enhance electrical continuity.
