A20T-250-4-1/2: Temperature Swichgage®
A20T-250-4(240).jpg The A20T-250-4-1/2 Temperature Swichgage® is a diaphragm-actuated, 2" temperature-indicating gage with a built-in electrical switch for tripping alarms and/or shutdown devices.

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 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. Contacts are isolated through ground. This gage has a self-cleaning motion to enhance electrical continuity.
