20TE-250-20-1/2 2" Temperature Swichgage® (10703353)
20TE-250-20-1/2: 2" Temperature Swichgage®; 130-250° F. temp range; internal SPDT snap-switch; 20 ft. capillary length (10703353)
The 20 Series (2 inch/51 mm dial) Swichgage models are diaphragm actuated, temperature-indicating gages with built-in electrical switches for tripping alarms and/or shut-down devices.
Swichgage®instruments are built in the USA and have protected engines and equipment in applications such as oil and gas, marine, irrigation, construction and trucking applications to monitor engine coolant, crankcase oil, transmission oil and others for more than 80 years.
The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, breakresistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument. These vapor-actuated gages feature 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.
This model has an instrument internal snap-switch with internal SPDT snap-switches instead of the single pole/pointer contact(s). When the switch closes on rising temperature, it becomes set. As temperature decreases, the switch resets.
