Abstract

Zum Überwachen einer Verdrängermaschine mit einem periodisch seine Position in einem Arbeitsraum ändernden Verdränger wird ein Systemdruck als Funktion einer Verdrängerposition erfasst und der sich ergebende verdrängerpositionsabhängige Systemdruckverlauf mit einem erwarteten verdrängerpositionsabhängigen Systemdruckverlauf verglichen wird, um Funktionsstörungen festzustellen.
