Torque detector for small capacitance
Made to order
MDシリーズ
The MD series torque detectors detect the output torque from small, precision motors to various mechanisms with high accuracy and high resolution.
Our phase difference detection method enables the measurement of minute torques with a minimum unit of 0.001 mN·m (when using MD-501C).
Furthermore, the MD series is incorporated into the MT series for micro-torque measuring devices and has gained a proven track record and reliability as a performance testing device for small, precision motors.
