利用自补偿技术提高LVDT传感器的稳定性

Improving Stability of LVDT Transducer with Self-compensation Technique

本文阐述了一种用双次级线圈构成线性变化差动变压器(LVDT)传感器的新方法。这种传感器具有补偿由于环境温度变化,以及传感器激励不稳定等因素影响的能力。实验结果表明,这种具有补偿能力的传感器性能稳定,可在各种环境中使用。

In this paper,a new method of dual secondary coils for linear variable differential transformer(LVDT) transducer is discribed.The transducer has the capability to compe- nsate the variation in ambient temperature and the influence of factor with an unstable transducer's excitation,etc.The experimental results show this compensating transd- ucer is stable and suitable to both favourahle and unfavourable environments.
