摘要
介绍了一种LVDT信号调理电路的工作原理及其线路设计。该电路是单片式线性位移差分变压器(LVDT)信号调理电路,与LVDT配合,能够高精确性和高再现性地将LVDT的机械位移转换成单极性或双极性的直流电压。该电路内部设计有一个驱动LVDT的低失真正弦波振荡器,电路外围线路简单,使用方便。
A monolithic signal conditioning subsystem for linear variable differential transformer （LVDT） is presented, which is used in conjunction with LVDTs to convert transducer mechanical position into a unipolar or bi- polar DC voltage with high accuracy and repeatability. The circuit contains a low distortion sine wave oscillator, which drives the LVDT＇s primary coil. The circuit is designed to operate with a minimum of external components.
