20T-160-30-1/2 Temperature Swichgage (10701430)

20T-160-30-1/2: 2" Temperature Swichgage; 32-160¡ F. temp range; 30 ft. capillary length (10701430)

The 20T-160-30-1/2 is a 2" Temperature Swichgage with a steel case, a 30 foot capillary length with standard 1/2-14 NPT threading and a temperature range of 32-160¡F (0-71¡C).

The 20 Series (2 inch/51 mm dial) SWICHGAGE models are diaphragm-actuated, temperature-indicating gages, with built-in electrical switches 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. These vapor actuated gages feature 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.

For series 20T, 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.
