ABSTRACT:
In fill-level measuring devices that operate according to the FMCW principle, nonlinearity of the sensor signal depending on the time can result in measuring inaccuracies. The fill-level measuring device that operates according to the FMCW principle comprises a correction unit for the mathematical correction of the amplitude values or for calculating points in time of scanning the amplitude values on the basis of a reference correlation determined at the factory. In this way intermediate-frequency values that are identical to those of an ideal sensor can be derived.
