HBM has developed a range of torque transducers capable of providing highly accurate information to reduce maintenance and lengthen service life for the latest gearless systems in offshore wind power plants. Extremely high torques – often of the magnitude of several MN·m – occur throughout the drive train because the generator turns at a slower speed with the same power to convert wind energy into electrical energy.

HBM’s range of torque products extends from series production products to customized transducers to meet the demands of a wide variety of applications including determining a generator’s efficiency according to IEC 60034.

HBM has presented the technology at many important international wind energy events and will continue with its activities during the coming year. This includes attending the EWEA European Wind Energy Conference & Exhibition 2014 in Barcelona, Spain, as well as AWEA 2014 in the USA. Main topics include both solutions for generating wind power as well as component and structural testing.

Wind energy plants are a key technology for renewable energy with leading German statistics company, Statista, noting that gross power generation from wind power has increased in the last 10 years by nearly 200%. Professional measurement technology can be used to increase performance and service life of wind power systems.

HBM Test & Measurement offers intelligent hardware and software solutions for a wide range of applications: fatigue tests on rotor blades, simulation of realistic loading conditions, weighing of complete offshore plants and measurements of the extremely high torques that occur there. HBM offers the right solution for almost every kind of gear test bench of this magnitude and is established as the world market leader for high-precision torque measurements in the MN·m range.


Founded in Germany in 1950, HBM is today the technology and market leader in the field of test and measurement. HBM’s product range comprises solutions for the entire measurement chain, from virtual to physical testing. The company has production facilities in Germany, USA and China and is represented in over 80 countries worldwide.
