Gas thermometer

Abstract

The invention relates to a temperature testing device, in particular to a gas thermometer, which has a wide measuring range and can measure the temperature of an object in a high-precision and high-speed manner. The gas thermometer comprises a temperature measuring part and a temperature indicating part, wherein a gas storage ball is arranged on the temperature measuring part; the gas storage ball is connected with a gas-guide tube; an elastic force application device is arranged on the gas-guide tube; the top end of the elastic force application device is wrapped with an interlayer thin skin; an elastic force application object is arranged inside the interlayer thin skin; the temperature indicating part comprises a dial scale, a fixed tray and a rotating bar; the rotating bar is connected with the gas storage ball; a laser is installed on the rotating bar; the rotating bar is connected with the interlayer thin skin through a magnetic sheet; and a fixed rotation point is arranged at the tail end of the rotating bar. The temperature testing device can measure the temperature of the object in a high-speed and high-precision manner.

Description

technical field [0001] The invention relates to a temperature testing device, in particular to a thermometer with a large measuring range, which can measure the temperature of an object with high precision and quickly. Background technique [0002] Most of the known thermometers are filled with liquid inside the thermometer, and the purpose of displaying the temperature is achieved through thermal expansion and contraction of the liquid. However, ordinary liquid thermometers have a small reliable measurement temperature range, and the temperature rises and falls relatively slowly, which often affects the accuracy of the experiment during the experiment. In addition, the accuracy of ordinary liquid thermometers can only reach 0.1K level, which will cause inconvenience when high-precision temperature data is required. Although there is also an electronic thermometer in the prior art, the electronic thermometer has problems such as high price and short service life, and is not...

AI Technical Summary

Problems solved by technology

However, ordinary liquid thermometers have a small reliable measurement temperature range, and the temperature rises and falls relatively slowly, which often affects the accuracy of the experiment during the experiment.

In addition, the accuracy of ordinary liquid thermometers can only reach 0.1K level, which will cause inconvenience when high-precision temperature data is required

Although there are electronic thermometers in the prior art, electronic thermometers have problems such as high price and short service life, and are not suitable for ordinary households.

Therefore, it is very necessary to design a new type of thermometer that can overcome the shortcomings of existing thermometers, such as the small effective temperature range, slow temperature measurement speed, and low measurement accuracy of the thermometer.
