ONO SOKKI Torque Detector RH series

High rigidity: Highly accurate detection of torque fluctuation with high response

The RH series is a torque detector that can accurately detect torque fluctuations with high torsional rigidity about 4.5 times compared to the existing products.
 
Compared to a general torque detector

The power spectrum above shows the measurement result of the cogging torque of the RH series and a general torque detector.
The RH series has higher torsional rigidity than general detectors, and also its resonance frequency is higher. The torque measurement (the torque ripple due to the first order component of cogging torque) can be performed with higher accuracy. In addition, it enables to measure flat and higher frequency.
 

High speed torque measurement: Rotation speed up to 20,000 r/min
In motors of EV scooters and compressor for air conditioners, the demand for high-speed rotation has been increasing as well.
The RH series provides high-speed rotation measurement up to 20,000 r/min and stable measurement from low (*) to high speed rotation.
(2.5 times faster than the existing models)
 

Direct signal output: Ideal for installing into system
RH series can be used as a stand-alone torque detector without a display unit and the direct signal output has achieved cost saving.
 
Example of system configuration

 
High accuracy: Perform performance evaluation tests of motors and other equipment with high accuracy
The RH series torque detector has achieved highly accurate measurement with ±0.05%/FS of linearity including hysteresis (1/2 compared with the existing models).
 
Compact: Weight and volume are reduced to about 1/3 compared to the existing models
Smaller and lighter than the existing models and having the same center height to easily replace and handle.
