Measuring the world –
stress measurements and test drives
Utilising appropriate measurements, measuring runs and continuous monitoring enables us to record
loads in actual applications – whether for approval trials and tests, calculation and simulation or for
structure optimisation in problem cases.
We execute measurements of mechanical and electrical variables with static and dynamic loads under operating
conditions, install complete measurement chains including the process adaptation. Our many years of experience
guarantee effective problem solutions for status, condition and load analysis.
Irrespective of whether Helsinki or Melbourne, Düsseldorf and Dresden – we are never too far away. Our on-site measuring service can provide numerous possibilities: with high channel counts and sampling rates, harsh environmental conditions, autonomous measuring in the regular utilisation or under test conditions – we can provide you with as much measurement data as you require, you have the choice. In addition to executing measuring runs, we can also provide you with customised complete solutions: Creating measuring concepts, FE analysis, application of sensor technology, dismantling, measurement data evaluation and derivation as well as implementation of appropriate test procedures.
We provide the test in accordance with the application guidelines for distance and route trials for the rail vehicle sector according to DIN EN 13749 and VDV 152.
We can support you with long-term measurements for data acquisition in actual operation, for example for the assessment of the impact and effects on the service life or the operating strength verification. Furthermore, we can develop systems for monitoring of structures, components, systems and plants, which are directly tailor-made to your specific requirements – reliably informing about load or damage incidents immediately. We measure analogue signals such as DMS, accelerations and paths in conjunction with GPS and bus data during numerous assignments in various areas . This provides us and you with extensive assessments including location-based evaluation of measurement data with durations of several years. Our knowledge and experience enables us to create soundly based test load concepts for executing component testing, also in-house at the customers.

Modern measuring systems
Digital measurement technology as well as numerous, various transducer types enable collection, recording and processing of static and dynamic parameters – including force, torque, pressure, path, elongation, strain, speed, acceleration, temperature, relative air humidity and calculated variables. We can register elongation and strain in two ways – firstly as DMS based and, on the other hand, as optical (ARAMIS system, with in-plane and out-of-plane measurements for deformations). Rapid processes, such as free fall trials, are implemented by means of a high-speed camera. We not only evaluate the measured data values with commercially available software but also with our own software and visualise this data in real-time, such as for rain flow classification (also in real time), envelope calculation and according to additional algorithms. Telemetry systems enable us to collect and record measurement data from rotating components.
