THE APPLICATION OF ELECTRIC AXIS METHOD IN THE MEASUREMENT OF SHAFTS AND BORES BY CAPACITIVE SENSORS

本文在电场理论中的电轴法基础上,导出了局部场域的电容计算式,为电容式测轴和测孔传感器的设计提供了精确的理论依据。这一研究成果还为经典的电轴法开辟了新的应用领域。文中给出了几种简化式与精确式计算结果的对比,并给出了几个应用实例。

The capacitive computations of the local field derived from the 'electric axis method' in field theory, provides a close theoretical basis for the design of capacitive sensors in the measurement of shafts and bores. Besides electric power and dispatch transmission the results find the third application for the classical electric axis method.The paper presents the comparison between each approximate formula and that of the exact one, and several examples to illustrate the application of the results.
