Abstract

SE PRESENTA UN DISPOSITIVO DE TEMPORIZACION MAGNETINEUMATICO QUE PREVE UNA SEÑAL DE PRESION QUE OSCILA ENTRE UNA SEÑAL DE SALIDA ALTA Y BAJA. EL CICLO DE TRABAJO PUEDE SER VARIADO ASI COMO EL TIEMPO DE CICLO GLOBAL. UN DIAFRAGMA FLEXIBLE MAGNETICAMENTE POLARIZADO DIVIDE UNA CAMARA EN UN PAR DE SUBCAMARAS Y LA PRESION DIFERENCIAL ENTRE LAS SUBCAMARAS ES CONTROLADA PARA HACER QUE EL DIAFRAGMA FLEXIBLE ALEJE LA POLARIZACION MAGNETICA HACIA UNA POSICION Y PARA QUE VAYA A SU POSICION POLARIZADA. EL CONTROL DE LA SEÑAL DE PRESION DE SALIDA SE LLEVA A CABO VARIANDO LA RESISTENCIA EN CIERTOS PASOS NEUMATICOS QUE SON PARTE DE LA FUNCION DE CONTROL PARA LA PRESION DIFERENCIAL. EL DISPOSITIVO ES RELATIVAMENTE SENCILLO Y BARATO PARA CONSTRUIR Y SE CARACTERIZA POR TENER POCA PARTES MOVILES, ASI ES DE FUNCIONAMIENTO SEGURO Y CAPAZ DE UNA GRAN PRODUCCION Y UN BAJO COSTO DE FABRICACION.
