Abstract. The journey to the past of torque measurement technology begins in the 17th century. It takes us from the first incipiencies of torque measurement to the problem of the transfer of the measurement signal from a rotating shaft, which existed for several decades. This task was solved by the integration of high-precise digital measuring amplifiers in the torque sensors, which is expressed by broad application fields, today. The future will appertain to highly dynamic measuring sensors as well as to intelligent torque sensors, which are able to transmit their sensor-specific characteristics to evaluation devices.

Keywords: torque sensors, torque transducers, torque measurement technology, torque cells
