基于微型测力传感器特殊的使用环境和结构特征,本文提出针对性的校准方案,介绍了一种静重式微型测力传感器校准装置,该装置由力值砝码、平衡力臂、框式机架、自定心夹持装置、平衡游码等组成。经测试验证,校准装置的测量范围为1N~1000N,测量不确定度不大于1×10^(-3),可对0.3级及以下等级的微型测力传感器开展量值传递,有效解决了该类型传感器的校准需求。

Based on the special operational environment and structural features of micro force sensor,the paper proposes a targeted calibration solution,and introduces the deadweight type calibration device for micro force sensor,this calibration device is composed of force weights,balance arm of force,frame rack,self-centering clamping device,balance rider weight,etc.After testing and verification,the measuring range of calibration device is 1N~1000N,and the measurement uncertainty not exceeding 1×10^(-3),therefore this device can carry out the dissemination of the value of quantity for micro force sensor of grade 0.3 and below,which solves the calibration demands of micro force sensor effectively.
