一、前言小量程测力仪广泛应用于机械、轻纺、建材、冶金等部门,其传感器大多使用电阻应变式传感器。七十年代以来电阻应变技术有了新的突破,但传感器的蠕变现象和温度漂移所引起的输出特性变化仍然无法消除,影响着测量的精度。为此,我们采用微型计算机,综合传 First, the preface Small range dynamometer widely used in machinery, textile, building materials, metallurgy and other departments, most of its sensors using strain gauge sensor. Since the 1970s, a new breakthrough has been made in the technology of resistance and strain. However, the variation of the output characteristics caused by creep phenomenon and temperature drift of the sensor can not be eliminated, which affects the measurement accuracy. To this end, we use micro-computer, integrated transmission
