Frank W. Murphy 2” Temperature Swichgages® TEMPERATURE: 130-250° F - FITS STANDARD 2-1/16” OPENING

• Diaphragm-actuated, temperatureindicating gages, with built-in electrical
switches for tripping alarms and/or
shutdown devices.
• 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.
• Dial: Black with white markings.
• Case: Plated steel with polycarbonate, high-impact lens.
• Bezel: Polished stainless steel.
• 1/2” N.P.T.
