Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic scale calibration, in particular to a high-precision temperature-controlled electronic scale calibration device. Background Art
[0002] An electronic scale is a type of weighing instrument. A scale uses Hooke's law or the principle of lever balance to determine the mass of an object. Based on their structural principles, they can be categorized into three main types: mechanical scales, electronic scales, and electromechanical scales. An electronic scale primarily consists of a weighing system (e.g., scale pan, scale body), a force transmission system (e.g., lever force transmission system, sensor), and an indication system (e.g., dial, electronic display).
[0003] Before using an electronic scale, it is essential to verify its measurement accuracy. Currently, electronic scale verification is mostly done manually, which is not only inefficient and inflexible, but also inevitably leads to bumps and damage during manual operation, and the manual handling of weights can cause damage, which in turn leads to a decrease in verification accuracy. For some high-precision, temperature-controlled electronic scales, external wind factors can also affect their detection accuracy. Utility Model Content
