Embodiment Construction

[0031] figure 1 A measuring device is shown with a sensor 1 which converts a measured variable 2 into an analog electrical sensor signal (sensor raw signal) 3 . Before the sensor raw signal 3 is digitized in the analog / digital converter 5 and further processed in the digitized signal processing device 6 by means of signal processing software, the sensor raw signal is filtered and / or enhanced in the analog signal preprocessing device 4 , In this case, the processing is, for example, filtering, scaling or, when the sensor signal 3 is modulated with a modulation frequency f, at which frequency it is demodulated by means of the lock-in demodulation device 7 .

[0032] A change in measured variable 2 which is formed in sensor signal 3 as a disturbance signal component can be influenced in sensor signal 3 by vibrations or vibrations 8 . A compensation signal 10 is thus generated by means of the compensation device 9 , which is subtracted from the processed digitized sensor signal 1...

Abstract

A measuring device comprises a sensor for generating a sensor signal as a function of a detected measurement variable, a compensation device for detecting a chattering of the measuring device and for generating a compensation signal, and an evaluation device for generating a measurement result from a difference between the sensor signal and the compensation signal. The compensation device comprises a multi-axis MEMS inertial measurement unit with an acceleration sensor and / or a gyroscope, and the multi-axis MEMS inertial measurement unit generates a plurality of motion signals according to the number of axes. Furthermore, the compensation device comprises a calculator having a calculation module in order to model an interference signal part of the sensor signal from the motion signal, the interference signal part being caused by the vibration, and to output the signal as a compensation signal. The calculation module is trained such that, in the absence of the measurement variable, the difference between the sensor signal and the compensation signal is zero or less than a threshold value.

Description

technical field [0001] The invention relates to a vibration-sensitive measuring device having [0002] - the sensor, which generates a sensor signal based on the detected measured value, [0003] - compensation means that detect vibrations of the measuring device and generate a compensation signal, and [0004] - Evaluation means that generate a measurement result from the difference between the sensor signal and the compensation signal. Background technique [0005] Such a measuring device is known from DE 27 02 978 A1. Among them, the known measuring device is a non-dispersive infrared (NDIR) gas analyzer with an optopneumatic detection system having a detection chamber which is filled with gas and connected via a line to a flow sensor arranged therein, In order to detect the modulated infrared beam passing through the measurement gas. In order to compensate for disturbances of the measurement signal generated by the flow sensor, according to the aerodynamic disturbanc...
