摘要
我们国家的电阻应变式称重传感器在上一世纪80年代末期获得了快速的发展。当时的产品标准是GB7551-87《电阻应变称重传感器》,实施日期为1989年1年1日。后来有了GB/T7551-1997《称重传感器》,现在的标准是GB/7551-2008《称重传感器》。本文重点分析了标准的技术指标在标准的制修订过程中发生的变化,论述了标准对产品性能的推动作用。
Resistance strain gauge load cell in our country obtained quick development in the end of the 1980s. Product standard at that time was GB7551-87 ＂Resistance Strain Gauge Type Load Cell＂, whose implementation date was January 1, 1989. GB/T7551-1997 ＂Load Cell＂ was development later, and current standard is GB/7551-2008 ＂Load Cell＂. The paper mainly analyzes standard changes of technical specifications during preparation and revisal of standards, and discusses promotion function of standards on product performances.
