Abstract

UN SENSOR DE PRESION PARA CONTROLAR SISTEMAS DE AIRE ACONDICIONADO Y SIMILARES CONSTA DE UN RECEPTACULO PARA ALEJAR DOS UNIDADES DE ACCION RAPIDA QUE OPERAN MECANICAMENTE Y UNA PARED DE SEPARACION DE FLUIDO. EL RECEPTACULO TIENE UN HUECO DE PASO CENTRAL PARA LA COMUNICACION CON EL SISTEMA DE AIRE ACONDICIONADO. EL RECEPTACULO ADEMAS CONTIENE UNA UNIDAD ELECTRONICA CONTROLADA POR UN DIAFRAGMA ELASTICO QUE LLEVA UN TRANSDUCTOR CONECTADO A UN CIRCUITO MICROELECTRONICO.
