Gas filled Thermometer

The gas thermometer or thermometer, also known as the comet thermometer, actually uses the same simple rules of complete gases and due to the increase in pressure due to the increase in temperature in a constant volume by measuring this pressure and calibrating it according to temperature, the temperature value Measured. In fact, a gas thermometer is a type of pressure gauge. The advantage of this thermometer compared to bimetallic thermometers is that it increases the length of its tail by several meters. In fact, the sequence of these thermometers consists of a capillary tube, which is usually shielded from the environment with the help of a shield, and only the part of the bubble at the end is sensitive to temperature and is considered as a sensor. In more advanced models, gas thermometers Neutralizing the ambient temperature by increasing the length of the sequence, use a capillary tube to the muzzle of the main pipe and reduce the circumference of the environment inversely from the value of the main temperature to obtain the exact value of temperature.
