Optical transmission method flange type torque meter TMHSA series

Custom

We offer a range of flange-type torque transducers with optical transmission, including the TMHSA, TMHSB models, which transmit signals optically. These transducers feature low noise, a space-saving design, and support for high-speed rotation, along with high rigidity and excellent fatigue resistance for stable use. Additionally, when combined with dedicated strain gauges and amplifiers, they provide long-term stability and high precision.

Features

・Compact size and light weight. Available for high speed measurement by bearing-free structure. (25 000 rpm: 100 Nm to 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-564 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.
