Abstract

Un transductor inductivo (1) de presión que incluye una estructura soporte (2, 3) en la cual hay montados un cuerpo metálico (8) que tiene una estructura plana (8a) en un extremo y una cavidad (8b) en el extremo opuesto, que está destinado a quedar expuesto a la presión de fluido a medir, y en el cual hay definida una pared delgada (8c), deformable elásticamente a manera de membrana bajo el efecto de dicha presión, entre la parte inferior de dicha cavidad (8b) y dicha superficie plana (8a); un inductor (10) que comprende un cuerpo de material ferromagnético (11) unido fijamente al cuerpo metálico (8) y que tiene una superficie plana (11a) enfrentada a dicha superficie extrema (8a) del cuerpo metálico (8), y que tiene un rebaje anular (12) que define un núcleo central (13) con un devanado (16) dispuesto en él y un manguito circundante (14); y una arandela separadora (9) de material paramagnético o diamagnético, de espesor calibrado, interpuesta entre el cuerpo metálico (8) y el cuerpo ferromagnético (11) de tal manera que el extremo distante (13a) de dicho núcleo (13) está enfrentado a la parte central de dicha pared deformable (8c) del cuerpo metálico (8) a una distancia calibrada del mismo; siendo la configuración tal que, a medida que varía la presión que actúa sobre dicha pared (8c), esta última se deforma elásticamente, variando la separación del hueco (17) de aire entre la pared (8c) y el núcleo (13) y variando, correspondientemente, la inductancia medible entre los terminales de dicho inductor (10).
