Abstract
Abstract Differential pressure measuring arrangement (10) comprises an evaluating unit (19) for determining the differential pressures which are lower than the lowest reference pressure value. The lowest reference pressure value is lower than the differential pressure on a new filter element (14). An Independent claim is also included for a process for determining the differential pressure using the differential pressure measuring arrangement. Preferred Features: The lowest reference pressure value is formed by a mechanical adjusting unit. The differential pressure measuring arrangement is arranged in the pipe system (11) of an I.C. engine.
