摘要
A differential-pressure measuring assembly comprising a differential-pressure measuring transducer for detecting the difference between the first media pressure and a second media pressure and for providing a differential-pressure measurement signal that depends on the difference between the first media pressure and the second media pressure; a first effective-pressure line, which is connected to a first pressure inlet of the differential-pressure measuring transducer in order to apply the first media pressure to the differential-pressure measuring transducer; a second effective-pressure line, which is connected to a second pressure inlet of the differential-pressure measuring transducer in order to apply the second media pressure to the differential-pressure measuring transducer; at least one temperature sensor for outputting a temperature signal that correlates with a temperature of the effective-pressure lines; and a processing unit for processing the differential-pressure measurement signal and the temperature signal; wherein the processing unit is designed to detect a significant correlation between a change in the temperature signal and the differential-pressure signal on the basis of the differential-pressure measurement signal and the temperature signal, and to assess the detection of a significant correlation as an indication of a plugged effective-pressure line.
