Reaction torque transducer "DRT"

16 Measureing range between ± 0 - 2 Nm to± 0 - 6000 Nm

  • for static use
  • active and passive execution
  • optionally with bracket

Datasheet

Features

  • Pulse screwdriver suitable. 
  • Lateral load insensitive. 
  • Permanently mountable.
  • Exchangeable adapters integrated.
  • Chip for sensor detection in connection with evaluation device GMV2.
  • For screw connection simulator

This transducer was developed for static testing of pulsed tools, torque wrenches, electric screwdrivers, etc. In combination with the universal torque meter GMV2 a torque wrench can be tested without falsifying the result by excessively tightening the wrench. 


The transducer can be mounted in any position with the help of the flange bracket to suit the tool to be tested. A variety of adapters are available for accepting the tool so that the tool can be tested with or without a socket. The device shaft is fitted with strain gages. It is not impacted by lateral loading because of the arrangement of the strain gages and an additional ball bearing.
