Description
SWICHGAGE models are diaphragm actuated temperature-indicating gauges with built in electrical switches for tripping alarms and/or shutdown devices. They have a range of 40°-120°C.
The 20T Series gauge mechanism is enclosed in a steel case coated to resist corrosion with a polycarbonate, break-resistant lens and a polished stainless steel bezel.
These vapour actuated gauges feature a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapour creating pressure against the diaphragm mechanism. The diaphragm translates this vapour pressure into a mechanical gauge reading.
For the 20T Series the gauge pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. The contacts are grounded through the SWICHGAGE case. It has a self-cleaning motion to enhance electrical continuity.
