产生电子皮带秤误差的原因很多。除显示仪表和传感器的原因外,皮带机本身是产生电子秤误差的一个重要来源。据统计,由于皮带的张力变化、振动、跑偏等原因产生的误差占总误差的60%以上,尤其是长皮带,其影响更为严重。所以,有些国家规定,电子皮带秤的皮带机长度不应超过30m。经观察,受皮带张力变化、振动和跑偏等因素的影响,常使表的瞬时指示波动范围达几吨甚至十几吨。为了减少上面的干扰,可采用图示双秤测量法。
Produced electronic belt scale error for many reasons. In addition to displaying the instruments and sensors, the belt itself is an important source of error in the scale. According to statistics, due to changes in the tension of the belt, vibration, deviation and other causes of error accounted for more than 60% of the total error, especially the long belt, the impact of the more serious. Therefore, some countries require that the belt length of the electronic belt scale should not exceed 30m. The observed changes in the belt by the tension, vibration and deviation and other factors, often make the table instantaneous range of instructions fluctuated up to several tons or even dozen tons. In order to reduce the above interference, can be used to measure the double scale.
