Ebook – Measuring torque correctly

Although torque is unquestionably an important mechanical quantity in the field of machine building, its significance is not confined to that area alone. The precise measurement of torque, particularly that which occurs in rotating components, places heavy demands on manufacturers and users of test benches. The situation is further complicated by the trend towards improving the mechanical performance of modern engines by increasing their speed of revolution, coupled with a desire for greater accuracy in such areas as the measurement of efficiency.

This challenge is met by continuous development taking into account the ongoing advances in the application fields. While torque shafts according to the original design principle are still used for certain applications, the full range of transducers now includes torque measurement hubs and torque flanges. Innovations in contactless torque transducers concern the transfer of power from the stator to the rotor and the transmission of measurement signals.

But even the most advanced measurement technology can only show its strength when specific rules are followed. This book is a comprehensive revision of the 1989 HBM publication The proper use of torque transducers. It gives an overview of important aspects concerning the use of torque transducers and provides a source of reference for resolving issues affecting applications…
