TMHS series

Optical transmission method flange type torque transducer TMHS

Torque Transducer TMHS series


Optical transformer method thin flange type torque
Compact size and light weight. Available for high speed measurement by bearingless structure. (Corresponds to rotational speed of 25 000 rpm, and 22 000 rpm for 500 NM or more capacity)
0.05 %R.O. in analog output and 0.02 %R.O. in digital output for the accuracy of detected value is achieved.
Easy to mounting and detaching by adopting with devided structure of stator (part of antenna).
Special transmitter OPT-563B is provided.
The detector for rotation speed and rotaional direction is prepared as an option.
High accuracy and low noise are achieved by the digital singnal transmission by the optical transmission method of the patent.

* Accuracy safe bending load and accuracy safe thrust load are the load (actual measurement value) which generate output error of 0.05%R.O.
* Accuracy safe bending load is the result of applying the load at the position of 200 mm from the flange edge.
* All are the gurantee over static load.
