Abstract

Un sensor de desplazamiento incluye un conjunto de imanes que tiene un alojamiento para montar a uno de un primer elemento y un segundo elemento movibles relativamente. Un conjunto de imanes está montado en un elemento y define un espacio longitudinal que tiene un eje geométrico a lo largo de su longitud. El conjunto de imanes incluye por lo menos un imán que tiene un polo norte y un polo sur que suministran flujo magnético de expansion en el espacio longitudinal y una pieza polar de conformacion de flujo en cada uno de los polos, norte y sur. Un conjunto sensor de campo magnético tiene un alojamiento para montar al otro del primer elemento y el segundo elemento para movimiento a lo largo de un eje geométrico en el espacio paralelamente al conjunto de imanes. En una realizacion, cada pieza de las piezas polares de conformacion de flujo tiene una forma pentagonal en un plano de configuracion de flujo primario, formando una primera cara que confronta al espacio longitudinal comprendido entre el primer imán y el segundo imán. En una realizacion, el imán es un imán cilíndrico adyacente al espacio longitudinal, y la primera cara de cada pieza polar de conformacion de flujo es cilíndrica y coaxial con el imán cilíndrico. Preferentemente la pieza polar tiene una cara troncoconica que confronta al espacio longitudinal adyacente a la cara cilíndrica.
