电子秤 1.工作原理：电子秤的工作原理以电子元件（称重传感器，AD转换电路，单片机电路，显示电路，键盘电路，通讯接口电路，稳压电源电路等电路组成。 2.使用功能：电子秤采用现代传感器技术、电子技术和计算机技术一体化的电子称量装置，才能满足并解决现实生活中提出的"快速、准确、连续、自动"称量要求，同时有效地消除人为误差，使之更符合法制计量管理和工业生产过程控制的应用要求。 3.电子秤是强制的计量器具，他的合格产品是有分度值e和细分值D的标准，是受计量法保护的产品。4.电子秤的分类： 1）.按原理分：电子秤 机械秤 机电结合秤 2）.按功能分：计数秤 计价秤 计重秤 3）.按用途分：工业秤 商业秤 特种秤 4).按放置位置分类：桌面秤 指全称量在30Kg以下的电子秤 台秤： 指全称量在30-300Kg以内的电子秤 地磅： 指全称量在300Kg以上的电子秤 4.精密天平 5).按度分类： I级： 特种天平 精密度≥1/10万 II级： 2.高精度天平 1/1万≤精密度＜1/10万 III级： 3.中精度天平 1/1000≤精密度＜1/1万 IV级： 普通秤 1/100≤精密度＜1/1000 Electronic scale (Has referred to electronic scale specialized websitehttp://www.dahuacn.com)1. Principle of work: The electronic scale principle of work (calls the heavy sensor the AD switching circuit by the electronic component the monolithic integrated circuit electric circuit the disy circuit the keyboard electric circuit the communication connection electric circuit electric circuit composition and so on voltage-stabilized source electric circuit. 2. Use function: The electronic scale uses the modern sensor technology the electronic technology and the computer technology integration electronic weighing installment can satisfy and fast solve "which in the real life proposed accurate is continual the automatic" weighing request simultaneously effectively eliminates the personal error causes it to conform to the legal system measurement management and the industrial production process control application request. 3. The electronic scale is the measurement appliance which the country forces to examine his certified product has examination scale interval e and subdivides value D the standard is counted the country the mensuration protection the product.4. Electronic scale classification: 1) According to principle minute: Electronic scale mechanical scale mechanical and electrical union scale 2) According to function minute: Counts the scale to count the price scale to count the heavy scale 3) According to use minute: Industry scale commercial scale special scale 4) According to lays aside the position classification: The tabletop scale points to the entire weighing below the 30Kg electronic scale tform scale: Refers to the entire weighing in the 30-300Kg electronic scale weighing bridge: Refers to the entire weighing above the 300Kg electronic scale 4. Precision balance 5) According to precision classification: I level: Special balance accuracy >= 1/10 ten thousand II level: 2. High accuracy balance 1/1 ten thousand <= accuracy < 1/10 ten thousand III level: 3. Center precision balance 1/1000 <= accuracy < 1/1 ten thousand IV level: Ordinary scale 1/100 <= accuracy < 1/1000
