The first torque sensor for industrial robots was developed 20 years ago – by Sensodrive. As a spin-off from the German Aerospace Center, we were able to make the torque technology from the German Aerospace Center's lightweight robot available for industrial use in 2003 – thus creating the basis for human-robot collaboration (HRC robotics).
Since then, more than a hundred thousand of our torque sensors have been installed worldwide in cobots, medical robots, force feedback and many other robotic solutions from well-known manufacturers. Our solutions continue to be the leading torque technology on the market, and we underline our technological leadership over and over again with further innovations such as the world's first BiSS torque sensor.
Premium quality for your application
Torque-controlled applications require a particularly high degree of customisation. In order to be able to offer you an attractive price-performance ratio as a premium manufacturer, we have therefore specialised in the production of medium and large quantities. And for small volumes we offer you our innovative SensoJoint complete drives.
Sensodrive torque sensors set standards in terms of quality, precision, cost efficiency and safety. They are available in numerous standard models that can be individually adapted to your requirements, in a patented design that offers compelling advantages for all areas of application.
Reliable quality made in Germany
In 2003 we were the first company to mass-produce torque sensors for robotic joints. Our patented technology is still unique today and thanks to our experience and leading expertise, we aim to remain the technology leader.
Quality made in Germany
We produce our torque sensors exclusively at the Sensodrive site in Wessling, Germany, and only use the highest quality components. This is how we guarantee the highest product quality with short and secure supply chains.
Reliable even under extreme conditions
Sensodrive torque sensors are extremely robust and optimally designed for use under extreme conditions in everyday factory work. Thanks to their particularly high rigidity and overload capacity, they feature an above-average service life and are also permanently completely maintenance-free.
Reliable balancing of external and internal disturbances
The patented torque sensors from Sensodrive can be used in highly sensitive work environments and always work with high precision, even when affected by disturbances:
The Sensodrive torque sensors' reliably high measurement accuracy makes them a high-end product that is second to none. The high-tech solutions also set new standards in terms of resolution, bandwidth and repeatability, and they stand out for their low noise as well.
Easy integration into your products
Compact lightweight construction
Thanks to our torque sensors' compact, disc-shaped design, they can be easily integrated into a wide variety of drives and robot joints. They require hardly any additional installation space and, thanks to their lightweight design, add hardly any weight.
A flexible sensor interface comes as standard with the Sensodrive torque sensors and enables use with a wide variety of interfaces:
Leading integration expertise
The highest quality products are useless without the associated integration expertise. We have over 20 years of experience in integrating torque sensors and are happy to support you with leading expertise from our experts. For large orders, our integration support is even free of charge.
We promise to provide you with the perfect solution. That is why the development experts from our Customizing Service will also adapt the torque sensors to your individual requirements on request.
Attractive price-performance ratio
The Sensodrive torque sensors give you the high-end product on the market – supplied at favourable conditions thanks to our partially automated production.
Thanks to their high quality, the torque sensors from Sensodrive are extremely resilient, less susceptible to faults and therefore highly available over the long term. They are also completely maintenance-free.
Short, secure and stable supply chains
We have deliberately decided against offshoring and produce all torque sensors ourselves in Germany. This way we can ensure your order will not be affected by problems in the supply chain.
Sensodrive is a pioneer in the field of human-robot collaboration. Our sensor concept is TÜV-certified and enables you to quickly and efficiently certify your applications according to ISO/TS 15066.
Whether it's a cobot, industrial robot, medical robot, exoskeleton or a steer-by-wire solution – the Sensodrive torque sensors impress in every industry and area of application that requires high-precision torque control. They are now installed in over a hundred thousand products from well-known manufacturers.
Our torque sensors are specialised for use in robot joints. As a basis for HRC robotics, they enable
force limitation to the environment and are the basis for the implementation of ISO/TS 15066.
In the medical field, for example, the Sensodrive torque sensors prevent disruptive and sometimes dangerous vibrations by actively damping vibrations in surgical microscopes.
By precisely measuring user forces and steering torques, the Sensodrive torque sensors enable the reliable implementation of force feedback applications and intelligent steer-by-wire solutions in automobiles from well-known manufacturers.
In modern exoskeletons, our torque sensors ensure the precise measurement and control of the supporting forces and thus enable safe interaction between humans and machines – in industrial as well as medical fields.
The fundamental principle of the Sensodrive torque sensors is based on the change in resistance of strain gauges, which is detected and interpreted with the utmost precision. The thing that makes the patented Sensodrive torque sensor technology so unique is that it comes already integrated in order to compensate for interference from the gearbox, bearings and external loads.
In addition to pure torque measurement, the torque sensor also functions as a bearing seat and connection component and can be used as a sealing component at the same time thanks to its patented diaphragm seal.
Thanks to its disc-shaped, compact design, it can also be fully integrated into joints and drives with almost no additional installation space required.
Our ready-to-install SensoJoint complete drives offer you the perfect combination of compact design and high-precision, high-performance drive.
In 2022, Sensodrive presented the first torque sensor ever to have a BiSS C Interface, giving you all the advantages of the BiSS C Interface technology with zero programming work:
BiSS is a trademark of iC-Haus GmbH
Over the last 20 years, we have developed over 50 different torque sensor types with a wide variety of specifications. The following table provides an initial overview of the range of possible configurations. The standard models can be individually adapted at any time.
