Torque Transducer Flange type optical transmission method/Shaft type optical transmission method torque transducer

Optical transmission method torque meter 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.
