To deliver precise measurements consistently, measuring instruments in industrial enterprises and test labs must be regularly calibrated to the national standard. Calibration is an essential quality assurance component that provides feedback on a measuring instrument's metrological properties. Are the measurements precise? Are the measurements repeatable? Are the parameters linear? Even very small measurement inaccuracies can drastically affect product and process quality. Drops in quality often result in rejects, rework, compensation claims, and unnecessary costs.
At GTM, we specialize in reliably calibrating your force and torque transducers, as well as all related calibrations. Our competence and experience are key to shaping the development of metrology. Our calibration technicians are highly experienced and skilled in calibration, metrology, and measuring technology. Our calibration lab is accredited by the German accreditation body DAkkS, and we operate the world’s largest private-sector compression/tension force measurement system (10 MN). As a leading provider of services in our field, we calibrate measuring instruments such as force, torque, and multi-axis transducers, as well as the voltage ratio of strain gauge measuring amplifiers.
All measuring systems in the GTM calibration lab are in-house developments. They are comparable to the standard machines for force and torque measurement that GTM delivers to National Metrological Institutes (NMI), calibration labs and sensor manufacturers around the world. Frequently they represent the national standard – the highest national instances (NMIs) – of the respective countries, for example in Germany, Switzerland or Brazil. As the first company worldwide to be accredited in the area of multi-axis calibration in 2005, GTM is the global pioneer in this field. GTM also supplies the Physical-Technical Federal Institute (PTB) in Braunschweig, which operates these standards by virtue of the Units and Time Act. Our lab is also accredited by the German accreditation body DAkkS according to DIN EN ISO/IEC 17025. Our customers can therefore be assured that we deliver reliable, traceable and high-precision calibration services. It is not without reason that we are among Europe’s leading providers of calibrations for force, torque and multi-axis transducers.
Engineers of the GTM calibration lab share their expertise in committees of the DAkkS and the German calibration service DKD. Together with other experts they discuss current issues such as calibration standards or develop calibration guidelines. GTM is therefore actively shaping the future of the sector.
To minimize calibration costs for high-rated loads, especially tensile force, our accredited calibration lab is equipped with various standardized mounting components to adapt to very high tensile force loads. This enables us to perform cost-effective calibrations within the range of 2 MN to 10 MN.
The force reference standards of the GTM calibration lab generally provide an accredited measuring range from 0.5 N to 10 MN.
To ensure correct centric introduction of the force vector in the case of level and plane-parallel force introduction surfaces of compression force transducers, we have compression force adapters with convex force introduction for forces up to 3 MN (Ø = 200 mm) and 10 MN (Ø = 360 mm).
If the customer does not provide all the necessary mounting components, the following adaptations can be made using existing components: Force transducers according to ISO 376 can be adapted using the in-lab test bars with a ball cup/ball nut combination for 2 MN, 4 MN, 6 MN, and 10 MN. We have in-lab threaded bushes according to ISO 376 with M90x4 threads on both sides for adapting 2 MN sensors, and with M125x4 threads for adapting 4 MN sensors. If the threads do not conform to the standard, then special threaded bushes must be manufactured or provided..
