Murphy by Enovation 20T-F-250-10-1/2 (10702240): 2" Temperature Swichgage®; 130-250° F. temp range; "FS" stud for closed loop w/ 518 tattletale; 10 ft. capillary length

 

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, break resistant 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.

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. They have a self-cleaning motion to enhance electrical continuity.
