摘　　要：对4-辊平整机压下位置测量系统Temposonics RH磁致伸缩位移传感器的外置安装方式和测量误差进行了分析和研究,并利用误差补偿原理和气动控制技术设计了一套"气动补偿装置",消除了Temposonics RH磁致伸缩位移传感器外置安装的测量误差和传感器敏感元件的弯曲现象。The outside installation mode and measurement error of the magnetostrictive position sensors Temposonics RH used for screw down position measurement of four-high skin pass mill were studied. A pneumatic compensation device was designed based on the principle of error compensation and pneumatic control technology, which can eliminate Temposonics RH measurement error due to outside installation and sensor bending.
