摘　　要：标准型直线式感应同步器尺寸较大,安装维护困难且易被污染,为此我们研究出柱栅这种新型的传感器。将其与传统的感应同步器进行了分析比较,对其机理进行了研究,并对概念样机的基本波形、栅性、正交性、幅值关系曲线、电压传送比等进行了一系列的实验研究,证明了柱栅原理的正确性和有效性。研究表明,柱栅概念样机在体积小于传统感应同步器的情况下,在信噪比和VTR参数等方面具有明显的优势。The standard linear Inductive Synchronous Transducer is large in size, difficult to install, easy to be polluted, so we developed a new digital linear displacement sensor, compared its characteristics with the traditional inductive synchronous transducer , analysed its working principle, and did a series of experiments on the conception sample of Columnsyn including basic waves, orthogonal characteristics, curves of voltage amplitude and voltage transformation ratio, which improved the correctness and effectivity of Columnsyn＇s working principle. It showed that under the circumstances of having smaller volume than traditional inductive synchronous transducer , columnsyn has remarkable advantage in SNR and VTR.
