20SD-250-1/2 Temperature Swichgage® (10703840)
20SD-250-1/2: 2" Direct Mount Temperature Swichgage®; no capillary tube; 130-250° F. temp range; 1/2-14 NPT threading (10703840)
The 20SD-250-1/2 is a 2" Direct Mount Temperature Swichgage®. This model has no capillary tube. It is a diaphragm-actuated, temperature-indicating gage with a built-in electrical switch for tripping alarms and/or shutdown devices. 1/4-18 NPT threading on the back of the gage with a 1/2-14 NPT threaded adapter.
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. 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.
