Abstract

The invention discloses a novel electronic balance, which takes an acceleration sensor as a main component and measures the weight of a tested object through a moment equilibrium principle. The novel electronic balance structurally comprises a micro-processing controller, the acceleration sensor, a pulling force sensor, a balancing relay, a motor relay, an LCD (Liquid Crystal Display) and a mechanical structure, wherein the acceleration sensor can measure the inclination angle of a force arm of the balance; and the balancing relay and the motor relay can adjust the balance of the force arm. The novel electronic balance disclosed by the invention has the advantages of novel design, simple structure, unique measuring method, reliable performance, high accuracy, small size and higher popularization and application value.

Description

technical field [0001] The invention relates to a balance, in particular to a novel electronic balance, which belongs to the technical field of measurement. Background technique [0002] With the rapid development of electronic technology and microcomputer technology, and applied to the field of balance, electronic balance has appeared. From the appearance of the first electronic balance in the world in the late 1970s, in just 30 years, a series of electronic balances of various specifications and categories have been developed, which are widely used in quality measurement in various industries. Electronic balances have advantages that mechanical balances cannot match. It has digital display, direct reading, fast weighing, easy operation, strong anti-interference ability, and adopts microcomputer technology to make it intelligent and multi-functional. It can be connected with printers and computers for online measurement, making data statistical analysis possible. , so the...
