25T-250-12-1/2 Temperature Swichgage (10703475)

25T-250-12-1/2: 2-1/2" Temperature Swichgage; 130-250¡ F. temp range; 12 ft. capillary length (10703475)

The 25T-250-12-1/2 is a 2-1/2" Temperature Swichgage. 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 12 foot capillary length with a standard 1/2-14 NPT threading, and a temperature range from 130-250¿F (54-121¿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 25T-250-12-1/2, 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.
