电子皮带秤由于受现场条件(如振动、高温与低温、潮湿等)的影响在一段时间内,称量结果往往有较大变动,因此,必须对在使用中的电子皮带秤进行定期标定。一、电子皮带秤的标定方法电子皮带秤的标定方法很多,但常用的有挂码标定、链码标定与实物标定三种。 1.挂码标定挂码标定即是将标准砝码置放(或悬挂)于电子皮带秤容易接受力并传递力最敏感的部位。这种标定方法的优点是简单易行,费用少,可做多点线性标定;其缺点是标定的精度比较低(约为±1.5%),搬动砝码的劳动强度大,因此,一般只能作为辅助标定,或作为新安装电子皮带秤的初步调试用。 2.链码标定链码标定是一种模拟电子皮带秤每米皮带
Electronic belt scale due to the site conditions (such as vibration, high temperature and low temperature, humidity, etc.) the impact of the weighing results tend to have a significant change over time, therefore, must be in use electronic belt scale calibration. First, the electronic belt scale calibration method Many electronic belt scale calibration methods, but commonly used hanging code calibration, chain code calibration and physical calibration of three. 1. Hanging Code Calibration Hanging Code Calibration is the standard weight placed (or hanging) in the electronic belt scale easily accepted force transmission and the most sensitive parts. The advantages of this calibration method is simple, low cost, multi-point linear calibration; the disadvantage is the calibration accuracy is relatively low (about ± 1.5%), moving the weight of the labor-intensive, therefore, generally only Can be used as a secondary calibration, or as a new installation of electronic belt scale for initial commissioning. 2. Chain code calibration Chain code calibration is an analog electronic belt scale per meter belt
