Abstract
Potenciómetro modulado magnéticamente basado en las propiedades magnetoresistivas de óxidos de manganeso. Esta invención consiste en el desarrollo de un potenciómetro, es decir un dispositivo de resistencia eléctrica variable, en el que se obtiene un cambio de resistencia en el elemento activo sin que exista contacto mecánico alguno con la parte móvil. El elemento activo del potenciómetro objeto de la presente invención, es un material magnetoresistivo. En él, la modulación de resistencia se obtiene al aplicarle un campo magnético variable. Mediante dichos materiales y un circuito magnético adecuado se fabrica el potenciómetro. Como propiedades características que lo diferencian de los potenciómetros convencionales hay que destacar la ausencia de contacto mecánico.Magnetically modulated potentiometer based on the magnetoresistive properties of manganese oxides. This invention consists in the development of a potentiometer, that is, a variable electrical resistance device, in which a change of resistance is obtained in the active element without any mechanical contact with the moving part. The active element of the potentiometer object of the present invention is a magnetoresistive material. In it, resistance modulation is obtained by applying a variable magnetic field. Using these materials and a suitable magnetic circuit, the potentiometer is manufactured. As characteristic properties that differentiate it from conventional potentiometers, the absence of mechanical contact must be highlighted.
