Murphy 20BTG water temperature gauge from the B-Series Murphy Swichgage instruments. This range of mechanical gauges has a diaphragm-actuated gauge and features a classic look featuring a stainless steel bezel, black dial and white graphics. The gauge is protected with a steel case and features a tough polycarbonate lens.

Temperature increases cause the fluid in the sensing bulb to vaporise and apply pressure to the diaphragm. This is converted to mechanical movements to operate the water temperature gauge. The pressure port features a pulsation dampener to help eliminate excess movement in the pointer to permit highly accurate readings. This gauge is said to be accurate within 2.4°C in the middle 1/3 of the scale, within 5°C in the lower 1/3 and within 2°C in the upper 1/3.

The Murphy 20BTG series water temperature gauges are suitable for monitoring engine coolant water, as well as for industrial and automotive applications.

This water temperature gauge is the Murphy 20BTG120C-5M, which measures from 50°C - 120°C and comes with a 5 metre long capillary. This capillary contains a 5/8 - 18 UNF union nut and is supplied with a 1/2" NPT adaptor nut as standard.
