Abstract
The influences of trouble signals on measurement technology have recently changed significantly due to new technologies. Due to the technology shift to more electric drives and hydrogen technology, sensors should also provide reproducible and reliable data even in this environment. In order to continue to ensure the quality of the measurement results, sensors and cable concepts must be reconsidered, modified and tested. The aim of this presentation is to point out these problems in connection with vibration and acceleration sensors with piezoelectric ICP®- and MEMS-DC technology and to show examples of improvements and solutions. Product improvements will be presented and measurement results from a test series in the field of e-mobility will be shown. Practical suggestions for optimal wiring, cable selection and ground concepts will be discussed. The perspective on the use of placebo sensors to verify measurement results is addressed. The findings and suggestions for improvement are a good help for test and measurement engineers in the development field of EMobility as well as eVTOLs for Urban Air Mobility (UAM) in selecting sensors and their use.
