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 th

Embodiment Construction

[0012] Such as figure 1 , figure 2 Shown, each component on it is fixed by fixing disc (1). When the temperature is measured, the pressure in the air duct (7) will change, and the pressure change will cause the pressure change on the elastic force-giving device (6). When the pressure on both sides is not equal, the turning rod (4) turns around the fixed turning point (5) until the pressure on both sides is equal. The corresponding pressure on each air duct (7) will reach a state of force balance with the force-giving device (6), that is, a static state. When stationary, the light (3) emitted by the laser (13) on the rotating rod (4) will irradiate the corresponding scale on the dial (2). According to the principle of similar triangles, when the light (3) is projected onto the scale When disc (2), its measurement accuracy will increase proportionally.

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...
