20T-250-50-1/2 Temperature Swichgage (10702058)

20T-250-50-1/2: 2" Temperature Swichgage; 130-250¡ F. temp range; 50 ft. capillary length (10702058)

The 20T-250-50-1/2 Temperature Swichgage is a diaphragm-actuated 2Ó dial (51 mm), temperature-indicating gage. This rugged, built-to-last instrument is fully sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel, and O-ring seals.

This vapor actuated gage Features a sealed fifty foot (50Õ) capillary tube, a sensing bulb, and a 130-250¡F (54-121¡C) temperature range.

Inside the 20T-250-50-1/2, 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.

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.
