电子吊钩秤用传感器与一般的称重传感器有所不同,使用时其受力形式比较复杂且多变,对抗偏载性能要求较高。目前电子吊钩秤使用的传感器绝大多数是拉式结构的电阻应变式称重传感器,而现有国家标准和检定规程对偏载性能均没有制定相应的检验方法。为此,本文提出一种偏载性能试验方法、评价标准及实际应用情况。 Electronic crane scale sensor with the general load cell is different, the use of its form of force is more complex and changeable, anti-eccentric load performance requirements are higher. At present, most of the sensors used by the electronic crane scale are pull-type resistance-strain type load cells, and none of the existing national standards and verification protocols have a corresponding test method for partial load performance. Therefore, this paper presents a partial load performance test method, evaluation criteria and the actual application.
