TMOS series

TMOS series



  •  Optical transformer method non-contact type torque transducer
     Making to low noise by digital signal transmission (ground brushless)
     Improve the stiffness and durability by the latest
    structural analysis technology.
     Easy to improving the performance and increase the capacity of the existed unit because of the same size.
     Improve the long term stability by applying the special gage.
     As equiping with the bearing mechanism, the installation of intermediate shaft receiving is unneccessary.
