摘　　要：提出了一种基于组合式力传感器设计的片剂硬度仪测量装置,通过小量程力传感器和大量程力传感器的转换扩大测量范围,实现在无拆卸的情况下对片剂硬度仪进行自动化测量。利用测量数据对片剂硬度仪的示值误差进行不确定度评定,实验结果表明利用组合式力传感器设计的测量装置测量范围从测量上限的10%~100%扩展到2%~100%,测量装置可保障片剂硬度仪的校准结果准确可靠。This article proposes a tablet hardness tester measurement device based on a combined force transducer,which expands the measurement range through the conversion of a small range force transduceranda large range force transducer,achieving automated measurement of the tablet hardness tester without disassembly.The uncertainty of the indication error of the tablet hardness tester was evaluated using measurement data.The experimental results show that the measurement device can expand the measurement range from 10%-100%of the rated value to 2%-100%,and the measuring device can ensure the accuracy and reliability of the calibration results of the tablet hardness tester.
