With the rapid development of electronic technology, the application of electronic balances is also constantly improving. It is gradually replacing mechanical balances with the characteristics of simple operation, fast and accurate weighing. It adopts modern sensor technology, electronic technology and microcomputer technology, and has very good advantages of mechanical balance. This article mainly starts with the working principle of the electronic balance, and discusses and analyzes the two main sources of measurement errors and their solutions.
High-precision electronic balances usually use electromagnetic force balance sensors, and electromagnetic induction electronic balances are different from electronic scales. The electronic balance uses the resistance strain sensor as the induction output, and the electromagnetic induction electronic balance is designed by using the principle of electromagnetic force balance. According to the electromagnetic force formula:
