UTM Series is an unprecedented torque meter that has achieved the following features and the specifications: compact & lightweight; the non-linearity of 0.03%FS; the max. rotation speed of 40,000 rpm; the safe overload of 500%.

Exceeded 35,000 units in cumulative shipments! The series has been used at many worksites for motor performance test, pre-shipment inspection of rotating parts and more.

Especially, UTMIII significantly reduces the impacts on effective accuracy by radial & thrust load as well as centrifugal force. Not only extremely stable measurement is possible during high-speed rotation, but also even minute cogging torque during low-speed rotation can be captured accurately.

With dramatically increased measurement accuracy, the UTMIII exhibits its highly reliable abilities for a wide range of applications from low to high-speed.

This time, we made a short clip comparing the accuracy of "UTMIII" and "UTMII" at a glance.

■ Why is load other than torque applied to torque meter?

For torque measurement, when interlocking shafts, misalignments on shaft center as illustrated below occur 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.
