Advance technologies in renewable and sustainable energy sources continues to drive the critical need to monitor, test, and validate concepts, equipment, and tools used in procurement. In the global energy industry, many of the alternative source technologies are inventive, newer, and require unique measurement solutions to take on the challenges found in R&D, testing, and production.

In addition, alternative energy sources in their infancy can be very cost prohibitive going from exploration to consumption. Therefore, it is important that quality, cost effective testing solutions are provided to help researchers, engineers and manufacturers minimize total costs. Interface force testing solutions help to solve and lessen the burden of these challenges by offering a wide range of test and measurement solutions.

New Interface case study reveals how our load cells were used by the PTB in Germany to calibrate and test the world’s largest machine that measures torsional forces related to wind turbines.

Interface force measurement sensors were requested to help Physikalisch-Technische Bundesanstalt (PTB), the national metrology institute of the Federal Republic of Germany, in the design of an innovative wind energy project. As the second largest metrology institute in the world, the PTB has an acclaimed international reputation in research relating to units and precise measurement.

PTB is a service provider for science, business, and society, and advises the German federal government on all metrology issues. Organizationally, the PTB is a departmental research facility and senior authority within the portfolio of the Federal Ministry of Economics and Climate Protection. For more than 135 years, PTB’s role has been making important contributions to advancing the energy transition, heat transition and climate protection with quality and speed.

Interface, working in tandem with our esteemed partner Interfaceforce e. K. in Germany, was asked to provide load cell solutions to use in the design and testing of the world’s first traceable torque measurements of up to 5 MN ∙ m for a wind energy facility. As a first of its kind project, the PTB needed to include high accuracy, quality test equipment to guarantee precise and reliable data. Interface solutions fit the exact requirements. Read the complete case study here.

Summarizing the engagement, PTB endeavored to construct a system with highly accurate and repeatable results, and one that enable bending moments, axial forces, and dynamic excitations of up to 3 Hz. Thereby, making it possible to realize a metrological characterization of dynamic influences in the (MN ∙ m) torque range, as well as in the MN force range. Working closely with PTB, Interface’s experts in Germany worked with the metrology lab engineers to identify the correct products for this unique calibration system.

These products are being used to calibrate and test PTB’s torque measurement system, allowing the system to provide accurate and repeatable results over time. The custom load cell products Interface provided PTB for this innovative wind energy system, as detailed in Interface Supports Incredible Wind Energy Innovation, included:

Series 1208 Model 1258 Flange Precision LowProfile® Load Cell with 2^nd bridge and two moment bridges for My and My
Series 1208 Model 1248 Flange Precision LowProfile® Load Cell with 2^nd bridge and two moment bridges for My and My
Series 1200 Model 1220 Universal Precision LowProfile® Load Cell
Model SM Super Mini High Accuracy S-Type Load Cell

The load cells that were chosen helped PTB to create the system needed for its wind energy facility, which allows multi-component transducers to be calibrated in a traceable and practice-oriented way for force and torque. The system is also now the world’s largest machine starting up at PTB, with which the large torsional forces that occur in wind turbines can be precisely measured for the first time.
