Novel electronic balance

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...

Problems solved by technology

The strain sensor is a sensor based on measuring the strain generated by the force deformation of the object. It has a simple structure and low cost, but its precision is limited, and it cannot achieve high precision at present; the capacitive sensor converts the measured change into a capacitance change Sensor, fast weighing speed, high cost performance, but the output is non-linear

At present, although the commonly used electronic balance is simple in structure and relatively accurate in measurement, it is not convenient enough to measure, the measurement accuracy is not high, the performance is not stable enough, and the volume is too large to be carried around.
