Abstract
Transductor de desplazamiento del tipo inductivo, que comprende un formador de material no magnético y no conductor, devanados dispuestos sobre dicho formador, y un núcleo deslizable dentro de este formador, estando conectado dicho núcleo, durante su uso, a un miembro cuyo desplazamiento ha de medirse, o formando parte de tal miembro, estando constituido tal núcleo por material eléctricamente conductor y no magnetizable y comprendiendo los referidos devanados un primer y un segundo devanados helicoidales interacoplados que tiene el mismo número de vueltas y se interconectan de tal manera que el flujo de corriente en un devanado es opuesto al del otro, siendo suministrados estos devanados en su uso con corriente alterna, de tal manera que se inducen corrientes parásitas en la porción del núcleo que se encuentra dentro del formador, dependiendo la inductancia de los devanados, por efecto de las corrientes parásitas, de la posición del núcleo dentro del formador.
