摘要
为了提高应变测量系统的测量精度,采用了相关检测技术测量应变电阻阻值,能显著抑制环境电磁干扰和放大器的直流误差、1/f噪声,提高了测量精度。
In order to improve the precision of the strain measurement system, correlation detection technology is used to measure the resistance of strain resistors. The environmental electromagnetic disturbance, DC error and 1/f noise of amplifier are rejected obviously by using this technology, hence the measure precision is improved greatly.
