Focusing on the problem that traditional LVDT measurement circuit requires many high-cost modules and that the performance is relatively low, a LVDT measurement system based on oscillation circuit is proposed and designed. LVDT coil is connected to a highperformance LC oscillator as a resonant inductance. Displacement is obtained by using the frequency shift of the resonance signal. System linearity is improved with the help of the resonator mathematical model and theoretical analysis. The experimental results of the prototype show that under the full displacement state, the frequency range span can reach 73 ~ 122 kHz. The sampling rate and resolution can be adjusted according to the actual needs. A submicronic measuring resolution of 16. 7 bits is achieved when the sampling rate is 200 Sps and the nonlinearity error is 0. 14% FS. The measurement system outperforms the traditional bridge circuit in most aspects, and does not need low distortion excitation and high-precision demodulation module. Besides, it has significant advantages in circuit cost and size.
