Transducer IRTT-B is the new generation of Atlas Copco torque and torque/angle in-line rotary transducers incorporating significant improvements in durability and accuracy. The system uses a patented solution that gives better resolution and longer life testing nutrunners in continuous tightening mode. The mechanics have also been completely reviewed to achieve a higher level of durability. IRTT-B memory chip is read by the STa 6000, IRC-Connect or STBench Joint Simulation Bench, which automatically recognizes the transducer, avoiding any possible errors.
