在力或力矩等参数测量中,目前大都采用电阻应变测量法。由于其间要经过一系列的信号转换和放大,所以如何保证机械参量正确地转换成电参量,这是测试工作中一个十分重要的课题。关于轧制力参数测量,由于轧机的工作环境恶劣,经常处于高温、冷却水、油、水蒸汽等的浸袭和传感器承受载 In the parameters of force or torque measurement, the current use of resistance and strain measurement method. As a result of a series of signal conversion and amplification, so how to ensure the correct conversion of mechanical parameters into electrical parameters, which is testing a very important issue. About rolling force parameter measurement, due to poor working conditions of the rolling mill, often in the high temperature, cooling water, oil, water vapor, etc. impregnation and load bearing
