Optical transmission method flange type torque meter TMHSA series
Appearance
■ Compact size and light weight. Available for high speed measurement by bearing-free structure. (25 000 rpm: 100 Nm ~ 300 Nm, 22 000 rpm: 500 Nm, 1 kNm, 16 000 rpm: 2 kNm, 3 kNm, 14 000 rpm: 5 kNm, 12 000 rpm: 10 kNm)
■ Measurement accuracy of ±0.02 %R.O. in frequency output and ±0.03 %R.O. in voltage output is achieved.
■ Stator antenna has a split configuration to facilitate mounting and detachment.
■ Special transmitter OPT-563B is provided.
The operation without this transmitter is available and the stator outputs ±10 V.
■ Calibraton software provided transfers commands between TMHSA and a PC, and allows users to read TMHSA setting parameter, proceed calibration, or write the number of moving average and the analog filter frequency.
■ 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.
