本文将说明新开发出的两种结构形式的质量测量装置的结构、工作原理与应用,具有移动式配重铁的测量机用于额定负荷范围为5～5000kg的称重传感器测量,还有一种100000kg的液压式测量机 阐述了两种新产品的结构特点、测量技术特性及优点 由于应用技术的最优化选择,及首次应用了新式检验方法,所以不同寻常处就在于测量范围扩宽了、经济性能提高了。 测量机内的测量误差:移动配重铁式测量机,小于实际值的30ppm(ppm一百万分之几);液压式测量机,小于60ppm。根据不伦瑞克(Braunschwerg)工程物理研究所(PTB)的国家标准,测量机的测量误差有可能小于100ppm,这是通过下述方法达到的:采用已获专利权的弹性铰接杠杆支承,或应用的GTM标准接收器极佳的可重复性
This article explains the structure, operation principle and application of the two newly developed mass measuring devices. The measuring machine with mobile counterweight is used for weighing sensor with rated load range of 5 ~ 5000kg, 100000kg hydraulic measuring machine expounds the structural characteristics of the two new products, measuring technology features and advantages of the application of the optimal selection of technology, and the first application of a new test method, so the unusual is that the measurement range has been expanded, the economy Performance improved. Measurement error in the measuring machine: Moving counterweight measuring machine, less than 30ppm (ppm parts per million) of the actual value; hydraulic measuring machine, less than 60ppm. According to the national standard of the Braunschwerg Institute of Engineering Physics (PTB), the measurement error of the measuring machine is likely to be less than 100 ppm by means of a patented elastic hinged lever or Excellent repeatability of the applied GTM standard receiver
