Title (EN) LINEAR AND ROTATIONAL INDUCTIVE POSITION SENSOR
(FR) CAPTEUR DE POSITION D'INDUCTION LINÉAIRE ET ROTATIF
Abstract:
(EN) An apparatus for providing a signal related to a position of a part comprises an exciter coil, and a receiver coil disposed proximate to the exciter coil. The exciter coil generates magnetic flux when the exciter coil is energized by a source of electrical energy, such as an alternating current source. The receiver coil generates a receiver signal when the exciter coil is energized, due to an inductive coupling between the receiver coil and the exciter coil. The receiver coil has a plurality of sections, the inductive coupling tending to induce opposed voltages in at least two of the sections. Embodiments of the present invention include linear sensors, rotational sensors, and novel configurations for improved ratiometric sensing.
(FR) La présente invention concerne un appareil pour fournir un signal lié à la position d'une pièce et qui comprend une bobine d'excitation et une bobine de réception disposée près de la bobine d'excitation. La bobine d'excitation génère un flux magnétique lorsqu'elle est activée par une source d'énergie électrique, comme une source de courant alternatif. La bobine de réception génère un signal de réception lorsque la bobine d'excitation est activée, et ce du fait d'un couplage inductif entre la bobine de réception et la bobine d'excitation. La bobine de réception possède une pluralité de sections, le couplage inductif ayant tendance à induire des tensions opposées dans au moins deux des sections. Les modes de réalisation de la présente invention comprennent des capteurs linéaires, des capteurs rotatifs et de nouvelles configurations pour améliorer le captage radiométrique.
