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.

Measuring device

A measuring device in which a non-electrical variable is converted into an electrical measurement signal via an electrical alternating current having a frequency, wherein the measurement signal contains a signal portion dependent on the non-electrical variable and is double the frequency, and a fault signal portion dependent on the alternating current and is at the frequency, where the measurement signal is pre-processed and digitized to generate a digital signal that is detected and processed to generate a measured value proportional to the non-electrical variable and to generate a fault signal value, wherein the fault signal value is utilized to normalize the measured value that is normalized in a normalizing stage, by forming the quotient using the square of the fault signal value, and is output as a normalized measured value.
