Abstract

Dispositivo para detectar la posición de las barras de regulación para reactor nuclear, que realiza su función sin ningún contacto mecánico cualquiera que sea la posición de un elemento móvil y en particular la de la barra reguladora siguiendo un recorrido determinado, por medio de un captador electromagnético que comprende: - un arrollamiento primario alimentado por una fuente de corriente o de tensión alterna para engendrar un fluido inductor; - un arrollamiento secundario acoplado inductivamente con el arrollamiento primario y provisto de una pluralidad de bobinas secundarias escalonadas; - comprendiendo dicha barra móvil por lo menos una parte magnética para modificar el acoplamiento inductivo entre dichos arrollamientos primario y secundario; caracterizado por el hecho de que a) dichos pares de bobinas secundarias están conectados eléctricamente en serie; b) un elemento de ponderación se encuentra afectado en cada par para engendrar una señal de salida ponderada al paso de dicha barra;c) un circuito de tratamiento va asociado al captador para comparar la diferencia de potencial ponderada con la diferencia de potencial no ponderada tomada en los bornes de los pares de bobinas secundarias en serie, y determinar la referencia fiable de la posición de dicha barra.
