Abstract

Il traduttore comprende un involucro rigido (1) con un'apertura (2a, 2b) per l'ingresso di un fluido di cui s'intende rilevare la pressione. Nell'involucro (1) è montata una membrana (4) destinata ad essere investita da tale fluido. Alla membrana è associato un nucleo magnetico (6) suscettibile di spostarsi all'interno di un avvolgimento (11) portato dall'involucro (1), contro l'azione di una molla antagonista (15, 115), in misura variabile in funzione dell'entità dello spostamento della membrana (4) e dunque in funzione della pressione del fluido che investe la membrana (4). L'induttanza dell'avvolgimento (11) varia pertanto in funzione della pressione del fluido. Fra il nucleo (6) e la membrana (4) è provvista almeno una lamina bimetallica (7) suscettibile di modificare la posizione del nucleo (6) relativamente a quella dell'avvolgimento (11) al variare della temperatura compensando almeno in parte la variazione dell'impedenza dell'avvolgimento (11).(Figura 2).
