$74.56
The 20T-250-4-1/2 is a 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 4-foot capillary length with a standard 1/2-14 NPT threading, and a temperature range from 130-250øF (54-121øC).
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 20T-250-4-1/2, 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.
