New measurement approaches for mechanical quantities based on strain gauge technology offer one feature above all else: the possibility to realize smallest measurement uncertainties. This is particularly important for metrological infrastructure, i.e. realization of metrological traceability chain to support applications in aerospace or in automotive industry. Achievements toward smaller measurement uncertainties are shown by realization of a novel torque reference sensor TN with improved usability for inter-laboratory comparisons in combination with a surprisingly compact precision amplifier called Quantum MX238B.

One of the fundamental challenges in analyzing wind turbine performance is the occurrence of torque creep under load and without load. This phenomenon significantly impacts the proper functioning of torque transducers, thus necessitating the utilization of appropriate measurement data analysis algorithms. In this regard, employing the least squares method appears to be a suitable approach. Linear regression can be employed to investigate the creep trend itself, while visualizing the creep in the form of a non-linear curve using a third-degree polynomial can provide further insights. Additionally, calculating deviations between the measurement data and the regression curves proves beneficial in accurately assessing the data.

“…By optimising the strain gauge carrier, finally the insensitivity to moisture could be significantly improved. It is especially important, as the uncertainty of the whole measurement chain is about the uncertainty of TN, while the uncertainty amount could be minimised and so we put much emphasis on it [11].…”

When evaluating the performance of measuring technology for mechanical quantities based on strain gauges (S.G.), one essential advantage is the possibility to realise smallest measurement uncertainties (MU).In these applications, S.G. must be able coping with the further tightening of MU budgets. Thus, two advances in the determination of uncertainty of high precision measurement chains based on S.G., are discussed in here. The two uncertainty contributions, what are not always considered so far, are humidity influences and long-term stability.To support today's sophisticated MU calculations, these two parameters have been further investigated and conclusions are drawn for each of measurement chain elements -reference transducers & precision amplifiers.
