The monitoring of bridge structures is one possible response to ageing infrastructure, which is a major concern in Central Europe. For this reason, current research trends are pursuing the development of new sensor systems, data transmission methods, data storage systems and evaluation algorithms. These endeavours are often referred to as digital twin. First prototypes have already been realised, the sensors installed, and measurement data recorded. However, to be able to analyse the data, it needs to be checked for plausibility. The plausibility check is demonstrated using the example of the digital bridge in Schwindegg, in which approximately 140 sensors were installed. This reveals sensors that measure well. However, the sensors that produce no, incorrect, or implausible values are also exposed. Furthermore, the study shows which sensors are suitable for which measuring tasks on the specific bridge and which are not. It highlights that it is not the number of sensors that matters but placing the right sensors in the right places.     «
