Shaft Style Optical Transmission Method

TMOS Series

Features
  • Optical transformer method non-contact type torque transducer
  • Low noise through digital signal transmission (ground brushless)
  • Improved stiffness and durability using the latest structural analysis technology
  • Easy to improve the performance and increase capacity of the existing unit because of same size
  • Improve long term stability by applying a special gage
  • Equipped with bearing mechanism therefore installation of intermediate shaft is unneccessary
