Metrologie für heterogene Sensornetzwerke und Industrie 4.0
(tm - Technisches Messen, Band 86, Heft 11)

Networks of sensors for different measured variables increasingly represent the backbone for a multitude of application areas, for example in industry, mechanical engineering and environmental monitoring. The merging of data (sensor fusion) plays a central role in the application and is generally a well investigated field of research. However, the consideration of metrological basic principles such as calibration, measurement uncertainties and thus traceability to the SI unit system for comparable and reproducible measurement results is comparatively little investigated.

THE ZEMA TESTBED

The ZeMA testbed was developed for condition monitoring, lifetime prognoses and end-of-line tests of electromechanical cylinders (EMCs) with a spindle drive. Long-term high load and speed driving tests are carried out at the testbed until an EMC failure occurs. Based on this, relevant sensors and characteristic signal patterns can be identified for condition monitoring as well as residual lifetime estimation of the EMCs.
