Catalog excerpts

Reaction Torque Transducer Torque ranges from 2 to 6000 Nm for static applications active or passive-model • suitable for impulse screwdrivers • side load insensitive • permanently mountable • exchangeable adapters • integrated chip for sensor detection • in connection with evaluation unit GMV2 • testing pulsed tools • torque wrenches • electric screwdrivers 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. Subject to change without notice DB013_DRT_EN_Rev.05 25.04.2025
