CAPACITIVE DETECTOR FOR THE DISPLACEMENT OF OBJECTS |
摘要 |
An object displacement sensor specifically adapted for high speed counting of passing nonmagnetic objects is disclosed which has a resonant circuit made up of at least one inductive element 2 and a condensor whose one plate consists of a conductive surface 3 and whose other plate is successively formed by each object 4 passing close to this surface 3. The resonant circuit is connected to a first oscillator 6 which determines the functioning frequency such that the signal issued from the first oscillator 6 is modulated in frequency to the rhythm of the passage of the objects 4. |
