摘要: A sensor device for a noncontact the control of moving strips conductive material. One or more detector electrodes are capacitively coupled to counterelement. An oscillator governs this coupling and forms two fields at edges strip. Lateral movement strip interacts with fields. The least one electrode is embraced by shielding electrode, being through an amplifier unity gain factor in such manner that potential follows electrode.
