从一九八四年开始我公司把30吨以上的地中衡、轨道衡陆续改制成了机电结合数字秤,对传感器安装位置和结构形式进行了改进,效果良好。按以往惯例机械秤改装成数字秤,大都把高精度称重传感器安装在地中衡、轨道衡第二杠杆或第三杠杆未端的力点处,配以显示表即成为机电秤。实践发现这种安装方式有一些弊病,经多次观察,当载重汽车以15km/h的速度开到承重台面上由于水平冲击力作用,此时安装在第二杠杆或第三杠杆未端力点处的称重传感器将出现轻微摆动现象,汽车时速越
Since 1984, our company has gradually transformed the balance of over 30 tons of ground and track scales into a combination of digital mechanical and electrical scales. The installation location and structure of the sensors have been improved with good results. According to past practice mechanical scales converted into digital scales, most of the high-precision load cell installed in the balance, the second lever or third rail lever end of the force point, together with the display table becomes the electromechanical scale. Practice has found that this installation has some drawbacks, after many observations, when the truck at a speed of 15km / h open to the load-bearing countertops due to the role of horizontal impact, then installed in the second lever or the third lever is not at the end point The load cell will appear a slight swing phenomenon, the more the car speed
