一、前言近年来,伴随着电子技术的进步,研制出了一些高精度的电阻丝式传感器,在商用电子秤到材料试验机之类的范围内得到了广泛应用。目前,大质量,大力值的标准传递系统如图1所示。图中对于传感器这类测力计一般用杠杆式标准测力机来检定,但是随着传感器精度的提高,也就希望提高这种检定用的标准测 I. Introduction In recent years, along with the progress of electronic technology, some high-precision resistance wire sensors have been developed and widely used in the range of commercial electronic scales to material testing machines. At present, the standard mass transfer system with large mass and strong value is shown in Fig.1. The figure for the sensor such dynamometer generally use lever standard dynamometer to test, but with the improvement of the sensor accuracy, also hope to improve this test with the standard test
