Product outline

High torsional stiffness(17000kNm/rad), 500% of safe overload
UTF is a flange type torque meter.
With high torsional stiffness, it can detect high-frequency torque fluctuation.
Due to the high save overload, it is also possible to work steadily with severe load for a long time.
It is suitable for testing automobile parts such as driving motors, generators, and decelerators.
