一、引言电子汽车衡主要由称重传感器、称重仪表、承载器和基础等4部分构成。在电子汽车衡器称重传感器技术、称重仪表处理技术、信号传输技术非常成熟的今天,由于提供电子汽车衡称重传感器、称重仪表的生产高度集中到2～3家企业,技术和测量器件高度同质化,大多数生产电子汽车衡的生产厂家只是焊接加工承载器,其产品中所使用的称重传感器和称重仪表几乎全是外购。因此,当前电子汽车衡质量差异主要取决于承载器质量的优劣。由于缺少承载器相对变形
I. INTRODUCTION Electronic truck scale mainly consists of weighing sensor, weighing instrument, carrier and basic 4 parts. In the electronic truck scale weighing sensor technology, weighing instrument processing technology, signal transmission technology is very mature today, due to the provision of electronic truck scale weighing sensor, weighing instrument production is highly concentrated to 2 to 3 companies, technology and measurement devices A high degree of homogeneity, the majority of manufacturers producing electronic truck scale is only welding process carrier, weighing sensors and weighing instruments used in their products are almost all purchased. Therefore, the current electronic truck scale quality differences mainly depend on the quality of the carrier. Due to lack of relative deformation of the carrier
