Abstract

Una celda capaz de convertir una presion diferencial en una senal eléctrica comprendiendo la celda: dos cámaras llenadas con un fluído incompresible y cadauna cerrada por una respectiva membrana adecuada para ser deformada bajo la accion de una presion externa, siendo las cámaras separadas la una de la otrapor una pared rígida; y un sensor asociado a dicha pared y que responde a las diferencias de presiones ejercidas a traves de la pared, entregando una senaleléctrica en respuesta a las mismaas; caracterizada por tener por lo menos un pasaje formado entre las dos cámaras con dimensiones aptas primeramente parapor lo menos atenuar una diferencia de presion parásita existente a través de la pared a una frecuencia que es menor o cero, y segundo, capaz de permitir adicho sensor detectar la diferencia de presion ejercida a traves de la pared a mayores frecuencias.
