Abstract

The invention discloses a high-performance electromagnetic scale which comprises a weighing disk, a balance mechanism and a counterbalance part, wherein the balance mechanism comprises a pivot point, a cross beam, a pointer, a scale, a projection screen, a light source and a center pillar; the counterbalance part comprises two magnetic poles, a slideable conductive rod, a coil, a detection and amplification circuit, a current control part and a power supply. The high-performance electromagnetic scale is controlled by a singlechip, can realize automatic measurement, automatic scale balance regulation and automatic measuring parameter acquisition and processing, has the characteristics of small measuring error, high speed and high precision, and brings great convenience to measure.

Description

technical field [0001] The invention relates to a balance, in particular to a high-performance electromagnetic balance, which belongs to the technical field of measurement. Background technique [0002] In quality metrology, the balance is an important measuring tool. It must be used to measure from the measurement of the measurement standard to the daily measurement of the value. It is not only closely related to people's daily life, but also makes a contribution to the development of science. made an indelible contribution. Until now, people are still constantly researching the balance, and with the help of modern means, various performances of the balance are improved to meet the needs of people's scientific research and daily life. However, with the development of science and the progress of society, people have higher and higher requirements for the accuracy, sensitivity and convenience of mass measurement. At the same time, people have to develop instruments suitable ...
