TMHFB series
TMHF
Feature
  • ・   Optical transformer flange type torque transducer
    ・   High revolution by bearingless structure.
    ・   Easy to mount and remove by adopting the division structure of stator (a part of antenna).
    ・   To transmit the digital signal by the optical transmission method of the patent, high accuracy (0.05 %) and the low noise have been achieved.
