Torque Transducer FF425 Rotary & Static

Series FF425 Rotary Torque Sensors and Series FF410 Static/Reaction Torque Sensors

The latest technology Datum Electronics Series FF425 and FF410 torque transducers have been designed to fit easily inline with any drive train or test bed using standard DIN size couplings. With Flange couplings at either end of the torque transducer it has many advantages over other torque measurement systems.

FF425 Rotary Torque Sensor and Transducers

The FF425 rotary torque transducer utilises a strain gauged shaft for accurate and reliable torque measurement and a set of rotating on shaft conditioning electronics, the digital signals are transmitted to the non-rotating part of the system or stator providing a reliable and highly accurate torque measurement solution. 

Using our revolutionary new electronics as used in our industry standard M425 transducer the FF425 gives customers higher resolution with up to 24bit resolution and the ability to choose their sample rates from 1 up to 4000sps.

The FF410 Static/Reaction Torque Sensor Range

The Datum Electronics Series FF410 Static torque sensor was developed following developments of our FF425 series of rotary torque transducers. The same basic shaft components and strain gauge technology have been applied to our FF410 Reaction transducer range providing a competitive option within the static transducer market. 

The Series 410 Reaction Torque Transducer design, along with many of the strain gauge principles have been applied, allowing us to keep the reaction torque transducer competitively priced with a high torsional stiffness included. 

Easy Fit into Rig 

The 410 Static Sensor easily fits into your existing test rig or drive train. Using standard DIN flanges, fitting and coupling the static transducer into your rig is made more efficient than other options available. The minimum operating envelope of the Series 410 reaction torque transducer starts from 100mm and will increase depending upon torque measurement requirements.
