Abstract

Un sensor de desplazamiento incluye un conjunto de imán que tiene un alojamiento para montar a uno de los elementos primero y segundo. Los imanesprimero y segundo se montan al alojamiento del conjunto de imán de modo que el polo norte de uni mán enfrenta al polo sur del otro imán y vice versa. Unapieza polar sobre cada uno de los polos de los imanes primero y segundo. Las piezas polares formadoras de flujo juntas que tiene configuraciones paraesculpir flujo magnético marginal en eles pacio longitudinal de modo que la densidad de flujo magnético en el espacio longitudinal varía substancialmentede manera lineal a lo largo de una línea en el espacio longitudinal entre los polos de los imanes que se enfrentan. Un conjuntode se nsor de campo magnéticotiene un alojamiento para montar al otro de los elementos primero y segundo. Un sensor de flujo magnético está montado al alojamiento del sensor sobre la líneaen el espacio longitudinal entre los imanes primero ysegundo. En un a realizacion, cada una de las piezas polares formadoras de flujo tiene una formade pentágono en un plano de diagrama de flujo primario, formando una cara angosta que enfrenta el espacio longitudinal entre los imanesprimero ysegundo. La cara angosta de cada pieza polar formadora de flujo es más ancha a través del diagrama de flujo primario que a lo largo de la longitud de la líneaen el espacio longitudinal.
