A20T-250-4-1/2 Temperature Swichgage (10703159)

A20T-250-4-1/2: 2" Temperature Swichgage®; Polycarbonate case; 130-250°F temp range; 4 ft capillary length (10703159)

The A20T-250-4-1/2 Temperature Swichgage® has a polycarbonate case and O-ring seals. This diaphragm-actuated, 2" temperature-indicating gage has a built-in electrical switch for tripping alarms and/or shutdown devices.
This model has a polished stainless steel bezel, a 4 foot capillary length, a temperature range from 130-250°F (54-121°C), and standard 1/2-14 NPT threading. 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.
