电子皮带秤的精度,除了与仪表本身精度、安装质量等因素有关外,还与正确的校验制度有关。本文拟就电子皮带秤的各种校验方法作一评述,并就实物校验设施的设计提供一些具体方案,最后,介绍了快速跳字以减少实物校验工作量的方法。一、常用的校验方法常用的校验方法有挂码校验、链码校验、实物校验三种。(一)挂码校验将一定重量的砝码挂在称量框架的标定刀刃上,启动皮带,观察瞬时量指示仪表的读数,并将一定时间间隔(一般大于3分钟,对长皮带应取转整数圈的时间)内累积计数器的跳字数与理论计算值相比较,这种校验方法叫挂码校验。砝码
Electronic belt scale accuracy, in addition to the accuracy of the instrument itself, the quality of the installation and other factors, but also with the correct verification system. In this paper, we will make a comment on the various calibration methods of the electronic belt weigher, and provide some concrete solutions to the design of the physical verification facilities. Finally, we introduce the method of reducing the physical workload by jumping words fast. First, the commonly used method of calibration Commonly used methods of verification are linked code verification, chain code verification, physical verification of three. (A) check the hanging code A certain weight of the weight hanging on the weighing frame calibration blade, start the belt, observe the instantaneous amount of indicator readings, and a certain time interval (usually more than 3 minutes, the long belt should be taken Turn the integer lap time) cumulative counter hop count compared with the theoretical value, this verification method called the hanging code check.
