Problems solved by technology
Therefore, the contact between the holder and the thermometer will cause a certain amount of heat transfer, which is negligible in daily life, but in physical thermodynamic experiments that have high requirements for the accuracy of temperature measurement, due to the clamping The error of the test result of the thermometer caused by the heat conduction caused by the device needs to be avoided as much as possible, and this problem has been a problem that has been solved by those skilled in the art for many years but has not been solved.

Embodiment Construction
[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0012] The magnetic levitation high-precision thermometer is composed of a top plate 1, a top ring 2, an exclusion ring 3, a transverse magnet 4, a thermometer 5, a column 6, a bottom ring 7, a lateral magnet 8 and a ring magnet 9. The top plate 1 is disc-shaped, and there is a circular hole in the center of the top plate 1 , and the upper end of the thermometer 5 is in the circular hole and fixed with the top plate 1 . The side wall of the thermometer 5 is covered with a foreign exclusion ring 3 fixed with the thermometer 5 as a whole, and the foreign rejection ring 3 is cylindrical. The side wall of the rejection ring 3 is inlaid and fixed with three cylindrical lateral magnets 8 along the circumference of the rejection ring 3, and the three lateral magnets 8 are evenly distributed along the circumference of the cross-sectional circle of the rejection...

The invention relates to a thermometer, in particular to a magnetic suspension high-precision thermometer which comprises a top disk, a top ring, a rejection ring, a transverse magnet, a thermometer, upright columns, a bottom ring, sidewise magnets and annular magnets. The upper end of the thermometer is fixed to the top disk. The side wall of the thermometer is sleeved with the rejection ring, the side wall of the rejection ring is provided with three cylindrical sidewise magnets, the upper ends of the three upright columns are combined with the top ring, the top disk is positioned above thetop ring and the thermometer penetrates through the top ring. an annular magnet is respectively inlaid and fixed in the lower end of the top disk and the upper end face of the top ring. The inventioncompletely eliminates measurement result errors caused by heat transfer due to the contact of the thermometer with other heat transfer objects, and is particularly suitable for physical thermodynamics experiments with higher precision requirements on measurement temperature.
Description
technical field [0001] The invention relates to a thermometer, in particular to a magnetic levitation high-precision thermometer. Background technique [0002] When existing thermometers measure the temperature of a gas or liquid in a container, the handle of the thermometer must be fixed in place by some kind of holder, and the holder of any thermometer will be connected to the container wall or other object to make it able to fix. Therefore, the contact between the holder and the thermometer will cause a certain amount of heat transfer, which is negligible in daily life, but in physical thermodynamic experiments that have high requirements for the accuracy of temperature measurement, due to the clamping The error of the test result of the thermometer caused by the heat conduction caused by the device needs to be avoided as much as possible, and this problem has been a problem that has been solved by those skilled in the art for many years but has not been solved.
