How can I work out the Torque for my test, I only have the Motor Speed and power?

Datum Electronics Ltd can work with the customer to calculate the expected torque using known measurement principle and suggest an appropriate torque sensor for you like our M425`

What if I don’t know my maximum torque measurement load?

Datum Electronics torque sensors have a safety factor built into them for 150% overload protection. Our technical sales team will be happy to work with you to help you choose the right sensor

What is the smallest torque that you can measure?

Our standard RS425 Size 1-Al is a 0-3Nm transducer which will give an accuracy of better than 0.1% of the full scale allowing for measurement in the Ncm range.

FF410
Flange-Mounted Torque Measurement for Static Applications

The FF410 is a flange-mounted reaction torque sensor designed for static torque measurement in test rigs, drive systems, and industrial setups. Built with high torsional stiffness and low maintenance requirements, it offers accurate, full-bridge strain gauge output across a standard range of 50 N⋅m to 30,000 N⋅m. Using DIN flange fittings and lightweight hollow shaft construction, the FF410 is easy to integrate and calibrate, making it a reliable solution for engineers needing precise, static torque data.

Applications

Static load testing in R&D environments
Non-rotating drivetrain component analysis
Structural torsion monitoring
Material torsion testing and validation
