10702067 Murphy Temperature Swichgage Model 20T-300-4-1/2

20T-300-4-1/2: 2″ Temperature Swichgage®; 140-300° F. Temp Range; 4 Ft. Capillary Length (10702067)

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. 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.

This product may vary on delivery times, as factories do not guarantee production due to lack of raw materials.
