Accurate torque measurement is critical in many industrial and R&D applications. Our torque sensor portfolio supports both static and dynamic measurements, from precision low-torque setups to high-load rotating systems. We offer static torque sensors based on strain gauge technology, as well as torque sensors for rotating shafts. These are designed for reliable measurements under real operating conditions. Applications range from robotics and automotive to marine, offshore and aerospace environments.
With a measurement range from 0.01 nNm up to 10 kNm, our solutions deliver consistent performance across both low and high torque applications. This makes them suitable for testing, monitoring and control in demanding systems.
Dynamic & static torque monitoring
We offer standard torque sensors but can also help you with a customized design or a complete measurement solution.
Torque sensors, also known as torque transducers or torque meters, are devices designed to measure the rotational force (torque) applied to an object. Torque is a critical parameter in numerous applications, ranging from industrial machinery and automotive systems to aerospace and medical equipment. These sensors convert mechanical torque into an electrical signal, providing valuable data for monitoring, control, and analysis.
Conventional torque sensors use strain gauges. These convert the mechanical torque into an electrical signal. Slip rings are typically used to transfer that signal from the measurement shaft. This tried and tested technology is rugged and reliable. Rugged, high-quality slip rings enable torque measurements over extended periods. They can endure rotating at up to 5,000 or 6,000 revolutions per minute. You need to amplify or visualize the measured signal? Our torque sensors are compatible with all amplifiers and display systems from our portfolio.
Our cutting-edge alternative to strain gauge technology uses Surface Acoustic Wave devices. This technology is based on an acoustic element that changes its resonant frequency under torsion. Your advantage: Thanks to the quick signal transfer from the rotary torque sensor, you can use these transducers for rotational measurements at up to 30,000 revolutions per minute.
Althen not only provides torque transducers for rotating applications – we also offer sensors for static reaction torque. They are also available as miniature versions. These sensors for measuring torque are all based on strain gauge technology. Multi-component transducers are a special type of torque measurement sensors. They measure torque along two or three measurement axes. This allows you to measure torque and static forces along multiple axes.
Are you looking for a digital interface for torque measurements? We are happy to design a custom sensor for you that includes a digital interface in addition to the analogue output signal. The digital interface makes reading out the measuring values simple. And it lets you scale each torque sensor to a specific measurement range as required.
For perfect signal processing in torque measurement, we provide a broad range of strain gauge amplifiers. Your systems already provide amplified output signals? You can connect them to our display systems, data loggers, or PC-based measurement data logging systems.
