Increased resistance to radial & thrust load

Influences that radial and thrust loads exert on effective accuracy were dramatically reduced.

■Why is load other than torque applied at torque meter?
For torque measurement, when interlocking shafts, misalignments on shaft center as illustrated below occurs by all means.
The devices that absorb radial and thrust loads caused by such misalignments are couplings. However, even the couplings cannot completely absorb such radial and thrust loads, resulting in an impact on torque measurement.

Experimental data
Experimental data
Above illustration shows the output change when one shaft end of UTMIII-2Nm is fixed, and 7N radial load is applied at another shaft end through the bearing.
Output changes depending on rotation angle.
While output value changes 0.1% at maximum with conventional torque meter, output value changes less than 0.01% with UTMIII.
