Abstract
La invención se refiere a un sensor de ángulo de giro en el que un imán (1) puede girar respecto de un probador (7, 14) sensible a un campo magnético acoplado a un cuerpo giratorio, cuyo ángulo de giro ("alfa") se va a medir. De acuerdo con los campos magnéticos simétricos usados hasta ahora, el ángulo de giro se puede medir directamente e inequívocamente solo en un margen no superior a 180º. Es objeto de la invención aumentar el margen de dicho ángulo de giro del sensor considerablemente. Con este objeto, se usa un campo magnético asimétrico de forma que el campo magnético máximo y mínimo medibles por el medidor sea superior a un ángulo de 270º entre sí. Las mejoras ventajosas de la invención comprenden otras posibilidades para ajustar el campo magnético a la forma deseada. Dichas posibilidades incluyen el cambio de un espacio de aire (6) con el ángulo de rotación y el uso de piezas polares asimétricas (18, 19).
