Optical transmission method torque meter TMOS series

Custom

We offer a comprehensive lineup of optical transmission torque transducers, including flange-type (TMHS/TMHFB/TMOFB) and shaft-type (TMOS/TMRS) models.
In addition to low-noise performance, a space-saving design, and high-speed rotation capabilities, these models provide high rigidity and excellent fatigue resistance for long-term, stable operation.
Furthermore, pairing them with our dedicated strain gauges and amplifiers ensures superior precision and long-term reliability.

Features

・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.
