Filling medium for thermometer

Abstract

The invention discloses a filling medium for a thermometer. The filling medium comprises raw materials by mass percentage of 60.3% of 180# aviation kerosene, 30.7% of 97# gasoline, 5.8% of industrial alcohol and 3.2% of banana oil. The filling medium for the thermometer is matched with copper alloy with high sensitivity, uses precise phosphor copper as an elastic body and can push the precise phosphor copper elastic body to drive a pointer to rotate. The filling medium has the advantages of being stable in product transmission linearity, high in display accuracy, high in safety, convenient to install and the like.

Description

technical field [0001] The invention belongs to the technical field of water temperature instruments, and in particular relates to a filling medium for a thermometer. Background technique [0002] The existing traditional water temperature instrument uses a single expansion medium to push the elastic element of the temperature instrument to drive the pointer to rotate, so as to achieve the function of temperature display. However, this traditional single medium has large display accuracy errors and unstable product transmission linearity for the thermometer. In order to further improve the display accuracy of the thermometer and the stability of the product's transmission linearity, it is necessary to propose a new filling medium formula. . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a filling medium for thermometers with high display accuracy and stable product transmission linearity. [0004] To ...
