Beschreibung
Zusammenfassung:	A differential pressure measuring arrangement, comprising: a differential pressure measuring transducer; a first differential pressure line supplying the differential pressure measuring transducer with the first media pressure; a second differential pressure line supplying the differential pressure measuring transducer with the second media pressure; a temperature sensor; and a processing and evaluation unit for processing the differential pressure measurement signal and the temperature signal; wherein the processing and evaluation unit is adapted to determine a significant correlation between a change of the temperature signal and the differential pressure signal and to consider such as indication of a plugged differential pressure line and is further adapted to test whether a considered indication of a plugged differential pressure line can be verified based on additional process data, which preferably were not registered by the differential pressure measuring transducer.
