MEASUREMENT ENGINEERING

We are measuring quickly, efficiently and correctly.

Based on our numerous R&D projects for technology leaders, we have an excellent measurement infrastructure. Our experienced staff will advise you in advance on the measurement design in order to prevent unnecessary or incorrect measurements, to capture and process data efficiently, and enable validation in the context of modeling and simulation. Thus, nothing stands in the way of a successful project execution through fast, cost-effective and correct measurements.

System analysis based on
measurement data

“The whole is more than the sum of the individual parts” – Nowadays it is no longer sufficient to look at individual components to assess and prevent system failures. The increasing complexity of systems makes the analysis and the subsequent diagnosis more and more difficult. Unforeseen system failures due to errors in individual components in productive systems must be avoided at all costs. We solve this problem with a system analysis based on measurement data. We include all relevant parts in the analysis and carry out the necessary measurements to give our customers a better understanding of the system. In addition to the classic analysis methods, our digital engineering know-how also allows the use of the most modern analysis methods such as data-based models.
