Abstract

La presente invención se refiere a un sensor de presión que responde a una base de cambio de presión predeterminada en un medio fluido de un sistema sensible a la presión, que comprende: a) una envoltura que tiene paredes que rodean una cámara de presión, b) una de dichas paredes siendo un diafragma flexible que separa la cámara de presión del sistema sensible a la presión, dicho diafragma siendo movible hacia adelante y hacia atrás entre una primera posición y una segunda posición en respuesta a un cambio predeterminado en la presión diferencial entre la cámara de presión y el sistema sensible a la presión, c) por lo menos una de dichas paredes siendo una pared permeable que es permeable a dicho medio fluido y teniendo una permeabilidad suficiente para permitir que el medio fluido pase a través de ella a una tasa que servirá para permitir la compensación de la presión en la cámara de presión y el sistema sensible a la presión para prevenir el desplazamiento del diafragma a la segunda posición cuando la tasa de cambio de presión en el sistema de presión es menor que la que es indicativa de una tasa de cambio predeterminada, la pared permeable siendo suficientemente impermeable para prevenir el paso del medio fluido a través de ella a una tasa que servirá para prevenir la compensación de la presión en la cámara de presión y el sistema sensible a la presión a una tasa que prevendría el movimiento del diafragma desde dicha primera posición hasta dicha segunda posición cuando la tasa de cambio predeterminada ocurre en el sistema sensible a la presión.
