Operating principle:
The gas thermometer operates on the principle of gas expansion in the thermowell. Changes in pressure are transmitted through the capillary to the pointer on the scale, ensuring accurate temperature display. This results in high sensitivity and stability of measurements.
Advantages:
- Does not require electrical power
- Quick response to temperature changes
- Convenient scale 0…120 °C
- Suitable for installation in a wide range of equipment
Installation difficulty:
Medium. Installation requires careful mounting of the thermowell and capillary. Avoid kinks or tension in the capillary tube.
Recommendations:
If the thermometer fails, it will not accurately display the temperature, which may affect the safety of the system. It is important to regularly check its functionality and replace it if necessary.
