Datum Electronics - Model RS425 -Non Contact Torque Transducer | High Range Torque Monitoring
The RS425 is a high-performance, contactless torque sensor designed for inline installation in high torque drivetrains and test rigs. With a bearingless architecture and strain-gauged shaft, it delivers accurate, friction-free torque monitoring in both static and dynamic applications. Its robust design supports high-speed torque in harsh environments while maintaining long-term reliability and minimal maintenance.

Contactless Torque Transducer with a completely separate rotor and stator
The Series 425 Contactless Torque Transducers can be adapted to replace existing drive shafts on test rigs and in drive lines, saving the time and cost of designing in special couplings and intermediate shafts to accommodate conventional torque transducers. We are able to modify the ends of the transducer to best suit your requirements, and can even design bespoke ends to fit. By measuring torque on longer drive shaft, you prove the accuracy of the measurement and its tolerance to offset loads. Using a direct replacement with a lightweight rotor the dynamics of the driveline are maintained.
RS425 Rotary Torque Transducer
The RS425 rotary bearingless torque transducer utilises a strain gauged shaft for accurate and reliable torque measurement and a set of rotating on shaft conditioning electronics, where the digital signals are transmitted to the non-rotating part of the system or stator providing a reliable and highly accurate torque measurement solution. The rotor is continuously powered, enabling static and rotary torque measurement to be made. Not only does the RS425 Series offer great technical advantages, but this range of contactless torque sensors are also competitively priced.
