Abstract
UN INDICADOR DE LA CONTRAPRESION EN UN FILTRO DE ESCAPE (10) QUE INCLUYE UN DETECTOR (12) PARA MEDIR LA CONTRAPRESION EN EL SISTEMA DE ESCAPE. EL DETECTOR ENVIA UNA SEÑAL QUE ES PROCESADA PARA INDICAR QUE UN ELEMENTO FILTRANTE DE ESCAPE ESTA LLENO. EL INDICADOR INCLUYE UN TEMPORIZADOR (24) PARA QUE LA SEÑAL CORRESPONDIENTE A LA PRESION SE MANTENGA DURANTE UN PERIODO DE TIEMPO PREDETERMINADO ANTES DE INDICAR QUE EL ELEMENTO ESTA LLENO. EL APARATO PUEDE INCLUIR TAMBIEN UNOS DISCRIMINADORES DE ALTA Y BAJA FRECUENCIA PARA PROCESAR LAS SEÑALES QUE SE ENCUENTRAN DENTRO DE UNA GAMA DE FRECUENCIAS DE SEÑALES PREDETERMINADAS CORRESPONDIENTES A LAS VELOCIDADES DE FUNCIONAMIENTO DEL MOTOR. POR TANTO, DEPENDIENDO DE LA OPERACION DEL VEHICULO, SE INDICARA QUE EL ELEMENTO ESTA LLENO TANTO DURANTE UN FUNCIONAMIENTO DEL MOTOR A ALTA VELOCIDAD COMO DURANTE UN FUNCIONAMIENTO DEL MOTOR A BAJA VELOCIDAD.
