Abstract

A measuring device includes a sensor generating a sensor signal in dependence upon a detected measured variable, a compensating facility generating a compensation signal in response to detected shocks, and an evaluating facility generating a measurement result from a difference between the sensor signal and the compensation signal. The compensating facility includes a multi-axis MEMS inertial measuring unit having an acceleration sensor alone or together with a gyroscope and generating a plurality of movement signals in correspondence to a number of axes, and a computer including a computational model trained to model an unwanted signal portion of the sensor signal in response to the shocks caused by the movement signals, and to output the unwanted signal portion as a compensation signal. The computational mod& is trained such that absent a measured variable, the difference between the sensor signal and the compensation signal is zero or is below a predetermined threshold.
