Torque Transducer
> TMOFA
TMOFA series
・
Optical transformer flange type torque transducer
・
High revolution by bearingless structure.
・
Easy to mount and remove by adopting the division structure of stator (antenna).
・
To transmit the digital signal by the optical transmission method of the patent, high accuracy (0.1%) and the low noise have been achieved.
