1. A shock-sensitive measuring device, comprising:
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 of the measuring device; and
an evaluating facility generating a measurement result from a difference between the sensor signal and the compensation signal,
wherein the compensating facility comprises
a multi-axis MEMS inertial measuring unit including an acceleration sensor alone or together with a gyroscope and configured to generate a plurality of movement signals in correspondence to a number of axes, and
a computer including a computational model embodied and 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, said computational model being trained in such a manner that absent a measured variable, the difference between the sensor signal and the compensation signal is zero or is below a predetermined threshold.
