"DRW-K" Torque sensor optionally with keyway

19 torque range ± 0 - 0,5 Nm to ± 0 - 20.000 Nm 

  • No maintenance needed
  • Wide application range 
  • 100% torque monitoring 
  • Small size
  • Option keyway

Because of their compact design, the DFW-K transducer series is suitable for applications in the lab and in industry. As these devices do not rotate and have no moving parts, they require absolutely no maintenance and do not suffer degradation due to wear. 

Also available in an active version in combination with the DMSVE amplifier unit.
