FF410 Reaction Torque Transducer

FF410 static reaction torque transducer has been designed with nominal rated torque levels from 250 to 10,000 nm. Using standard din flanges, this static transducer is made more efficient than other options available.


The Datum Electronics Series 410 Static (non-rotating or reaction) torque sensors were developed following demand from our customers, looking to measure static or reactionary torque. The FF410 series of static torque sensors use the same basic shaft components and strain gauge technology, that have been applied to our 420 Rotary Torque transducer range, providing a cost-effective torque measurement solution for the static transducer market.

FF410 Static Torque Sensor Measurement Range
The Series 410 Reaction Torque Transducers have been designed with a nominal rated torque level in Nm. Nominally rated torque levels include:

  • 250Nm
  • 500Nm
  • 1,000Nm
  • 2,000Nm
  • 5,000Nm
  • 10,000Nm

Easy to Install within Torque Test Rig
The 410 Static Torque Sensor and Reaction Torque Transducer 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.
