As part of its strategy to offer the highest service quality, HBM now provides torque calibration for a maximum of up to 60 kN∙m torque. This allows HBM’s DKD-accredited laboratory at Darmstadt, Germany, to calibrate transducers up to a length of 2.20 m and a maximum diameter of 75 cm. The size means that HBM can also calibrate special transducers, such as original vehicle shafts that have been retrofitted for torque measurement by installing strain gages. Notes HBM, “Determining the driving torque of vehicles as large as trucks is not a problem”.
Calibrations on the largest machine are working standard calibrations, where the processes have been simplified compared to the more complex DKD calibrations. Working standard calibrations are specified and documented by HBM while traceability meets ISO 10012 standards through HBM’s quality management.
Accreditation by the DKD association (German Calibration Service) certifies the specified accuracy. DKD accreditation meets the requirements of the ISO 17025 norm. This standard defines the requirements for testing and calibration laboratories and is becoming increasingly important at an international level. DKD-accredited torque calibration systems at HBM cover torque ranging from 2 N∙m to 25 kN∙m.
HBM has a long tradition of providing complete measurement chains from measurement technology products through to software and complementary services from a single source. The in-house DKD-accredited laboratory secures HBM’s position as leader in the calibration of torque transducers.
