摘要
A position detection method and apparatus is disclosed which utilizes an electromagnetic probe as the control element in a relaxation oscillator circuit. The probe is energized by a pulse voltage waveform and the decay time of the induced transient probe voltage is utilized to modulate the frequency of the pulse generator. The probe transient voltage decay time is influenced by the proximity of an electrically conductive or magnetic object. Therefore, a frequency output is generated which indicates the position of the conductive or magnetic object.
