Dial Thermometer - Gas Filled (Temperature Gauge)


Radix Gas-filled Dial Thermometers, with a sensing bulb filled with nitrogen gas, are of rugged design and all stainless steel construction for long life in harsh environments. Dial sizes of 2.5", 4” and 6” (63, 100 and 150 mm) are available, depending on accuracy, resolution and readability requirements.

This model measures temperatures between -200 °C and +800 °C. Mounting options are bottom, back and all-angle. The all-angle design allows rotation and angling  of the entire case (180°) for the dial face to be read easily. Additionally, Gas-filled Dial Thermometers (Temperature Gauges) can be remote mounted with a capillary. A SS316 / SS316L stem provides corrosion resistance with  6 or 8 mm stem diameter as standard; 10, 12 and 14 mm diameter is optionally available. Immersion length is 130 mm (min) and  above with 250 mm as standard. Threaded or flanged process connections in fixed or adjustable design are available.

Use of a thermowell is recommended for applications where the stem of the gas-filled dial thermometer may be exposed to high velocity, pressure or corrosive fluid. Also, use of a thermowell permits instrument replacement without disturbing or shutting down the process. IP68 rating can be offered for dust tight,  weather-proof applications as well as protection from complete, continuous submersion in water.
