应用控制理论和电子技术,给普通机械天平加上电磁力自动平衡装置,就成为电磁自动天平。它不仅改善了机械天平的计量性能,减小了静态误差,而且改善了它的动态特性。它与通常的光学标牌天平相比,具有许多优点: 1.称量精度高,读数范围宽。 2.数字显示,实现客观读数,减少出现差错的机会。 3.调零、去皮容易、简便。 4.称量速度快,节省时间。 5.可同记录器、打印机、计算机连接, Application of control theory and electronic technology, to ordinary mechanical balance with electromagnetic force balancing device automatically become electromagnetic automatic balance. It not only improves the metrological performance of a mechanical balance, reduces static errors, but also improves its dynamics. Compared with the usual optical signage balance, it has many advantages: 1. Weighing accuracy, wide reading range. 2. Digital display, to achieve objective readings to reduce the chance of errors. 3. Zero, peel easy, easy. 4. Weighing speed, save time. 5 with the recorder, printer, computer connection,
