    • An oscillator circuit outputs an oscillator signal with a frequency corresponding to an inductance of a displacement detector coil. An oscillation cycle measurement circuit measures a cycle of the oscillator signal output from the oscillator circuit, and outputs a signal corresponding to the measured cycle. A squaring circuit calculates and outputs a square of the signal output from the oscillation cycle measurement circuit. By the calculation and output of the square of the oscillator signal cycle, a square root component of the product of inductance and capacitance components is eliminated, so that the output signal changes linearly relative to the displacement of a displacement body. As a result, the linearity of the output signal relative to the displacement of the displacement body can be improved.
    • 振荡器电路输出具有对应于位移检测器线圈的电感的频率的振荡器信号。 振荡周期测量电路测量从振荡器电路输出的振荡器信号的周期,并输出与测量周期对应的信号。 平方电路计算并输出从振荡周期测量电路输出的信号的平方。 通过振荡器信号周期的平方的计算和输出,消除了电感和电容分量乘积的平方根分量,使得输出信号相对于位移体的位移线性变化。 结果,能够提高输出信号相对于位移体的位移的线性。
