Abstract

Un sistema de bomba de fluido incluye una bomba que tiene una pluralidad de cilindros, cada uno teniendo un puerto de salida acoplado con un multiple de alta presion; un transductor de presion se acopla con el multiple y esta configurado para convertir los niveles de presion del fluido en el multiple a una senal de voltaje en una salida del transductor; el sistema incluye adicionalmente un digitalizador configurado para convertir la senal de voltaje del transductor a una senal digital en una salida de digitalizador de manera que, cuando un valor de la senal de voltaje es menor a un voltaje de referencia seleccionado, se produce un primer valor digital y, cuando el nivel de voltaje supera el voltaje de referencia seleccionado, se produce un segundo valor digital; un circuito de diagnostico que tiene una entrada acoplada con la salida de digitalizador esta configurado para detectar disfunciones de la bomba con base en las caracteristicas de la senal digital.
