HBM reference book offers overview of using torque transducers
Measuring torque correctly
HBM technical experts Rainer Schicker and Dr Georg Wegener have written a 272-page reference book, Measuring torque correctly, which is designed to offer a clear overview of all essential aspects of using torque transducers.
The book describes principle options for torque measurement and deals with the design and application of torque transducers most commonly used today.
The principal methods for measuring torque are described, along with information on how to address and solve problems arising in everyday applications.

This application note from HBM is intended to explain how the recently developed Ethercat, an industrial communication protocol that extends the IEEE 802.3 Ethernet standard, can provide the industrial sector with fast, real-time measurements that a standard Ethernet connection cannot. The limitations of a normal Ethernet connection include the fact that only small amounts of data is being transmitted at any one time, and that the messages originate when the client or master device ...
Users of strain gauges for multi-component force transducers — and particularly for wind-tunnel balances — at TU Darmstadt university found that it was a problem to use manufacturers’ strain gauges without influencing their characteristics. Thanks to funding from HBM, the university’s Yu Tao was tasked with developing the numerical simulation of a strain-gauge measuring point so that its characteristics could be calculated.
White paper: including reproducibility in the evaluation of simplified calibration procedures download
This study from HBM suggests a method that allows users to estimate the reproducibility error in torque calibrations without the need to perform several measurement series with the torque transducer being mounted in different mounting positions. The aim is to enable uncertainty estimations for simplified calibration procedures and the approach is to use statistical data gained from previous calibrations of transducers of the same type. The study shows how to select and classify past ...
The IEEE 1451.4 international standard is the basis for transducer electronic data sheets (TEDS), where information related to the transducer, such as serial number or nominal sensitivity, is stored in a chip inside the transducer. For bridge-type sensors, with a novel circuit it is possible to read the TEDS information for six-wire bridge sensors without additional wires by using the sense lines. This paper from HBM presents investigations of the influence of TEDS on measurement results.
This white paper from HBM describes a type of pressure transducer that provides accurate and dynamic pressure measurement up to 15,000 bar, using foil-type strain gauges. The strain gauge is the smartest choice for measuring ultra-high pressure, as the measuring body, which is made from special steel, can be designed freely according to the requirements of maximum pressure resistance plus the overload protection, as well as maximum sensitivity. The relationship between the two quantities ...
