摘要: Method and apparatus for measuring distance includes a capacitance probe positioned adjacent rotating member within the housing of such that between can be measured. The co-operate with each other so as to define capacitor. An oscillator comprising transmission line is electrically connected probe, resonat frequency value which function change in therefore
