Abstract

UN ELEMENTO DE ARRASTRE DE UN MECANISMO DE BOMBEO PERISTALTICO INCLUYE UN DISCO (24) QUE ROTA CON EL ELEMENTO DE ARRASTRE (18) Y TIENE DOS SECTORES TRANSPARENTES (27, 26) Y DOS SECTORES OPACOS (28, 29) QUE ALTERNAN CON LOS SECTORES TRANSPARENTES. AL TIEMPO QUE UN MOTOR DE MANDO (19) ROTA EL ELEMENTO DE ARRASTRE PARA BOMBEAR EL FLUIDO (13), UN UNICO SENSOR OPTICO (30) SIENTE EL DISCO Y PROPORCIONA UNAS SEÑALES INDICATIVAS DE SI SE HA DETECTADO UN SECTOR TRANSPARENTE O UN SECTOR OPACO. UN PROCESADOR (21) CUENTA EL NUMERO DE PASOS DEL MOTOR EN EL SECTOR OPACO O TRANSPARENTE DETECTADO Y, BASANDOSE EN EL NUMERO DE PASOS CONTADOS EN UN TIPO DE SECTOR DETECTADO O EL NUMERO DE PASOS CALCULADOS CUANDO OCURRE UN CAMBIO DE UN ESTADO A OTRO TIPO DE SECTOR, DETERMINA LA POSICION DEL MOTOR.
