摘要

本論文主要介紹使用雙探頭位移感測器來實現位移量測的方式，將複雜的線性化處理簡化，不必經由複雜的線性化處理造成時間上的成本損失
，挑出較佳的設計參數給予使用者參考及使用。文中以考畢子振盪電器為範本，設計感測器之感測電路，並探討其電容與電感對振盪頻率與峰值之影響，推算出電容與電感之間其最佳匹配性，另以最小平方法求解探頭位移變化之參數，用以得出雙探頭之位移關係。實驗結果顯示，此雙探頭位移感測器在-2mm ~ 2mm之位移變化下之線性度為10.5%。

This dissertation mainly introduces how to use dual-probe displacement sensor to realize the displacement measurement. It simplifies the complex linearization process and picks out the better design parameters to make the user easy and convenient to use without the complicated linearization costs time lost. In this paper,Colpitts oscillating electrical appliances as a model, the design of the sensor sensing circuit and to explore the capacitance and inductance of the oscillation frequency and peak impact, calculate the capacitance and inductance between the best match, the other with the minimum level The method solves the parameters of the displacement of the probe to derive the displacement relationship of the dual probe. The experimental results show that the linearity of this dual-probe displacement sensor is 10.5% under the displacement of -2mm ~ 2mm.
