Torque Detector

MD Series

Micro Capacity Type

Features
Specifications
General Specifications

The MD series torque detector is designed to measure the torque output from compact & precision type motors used in the electric & electronics industry, the automotive industries and so on, featuring outstanding low inertia and low starting torque. With the phase differential system, it can realize low capacity torque measurement as small as 0.001mNm.

Features

High accurate detection of micro capacity torque (mN·m)
Focused on measurement: Low moment of inertia and small starting torque
Wide measurement range: From stationary condition (0 r/min) to high rotation speed can be measured with one unit.
Applicable to new rotation detector (MD-0110 series option)
