Product outline

UTM series have been upgraded to UTMⅡ to better meet the various needs of customers!

Great improvements on the bandwidth (1 kHz), sampling rate (6 kHz), overload rating (500%), and so on have been made, while all great features of the existing model are succeeded.

We will continue to devote ourselves to research and development of unique products. Please feel free to contact us anytime for further information!

 



●Available in 17 different capacities ranging from 0.05 to 10000 N m.
●Cut-off frequency of 1 kHz with high-speed sampling at 6 kHz.
●Safe overload of 500%
●Power supply DC 24 V
●No external amplification required: ±5 V analog output voltage
●A rotational pulse generating circuit (4 pulses/revolution) is built in as standard.
●Improved noise immunity by adopting an insulated power supply

 

High accuracy, stability, slip-ring-less, and compact
  • Compact and easy to install
    The six models (0.05, 0.1, 0.2, 0.5, 1, 2 N m) are particularly compact and light: 54(W)×50(H)×40(D) mm in size, 200 g or less in weight.
  • High accuracy and stability
    1/10000 torque resolution with outstanding zero stability.
    UTMⅡ accurately measures tiny torque variations.
  • Maintenance-free
    No slip-ring.
    The lifetime of UTMⅡ is mainly determined by the lifetime of bearings.
  • Max. rotational speed 25000 rpm
    0.05 to 10 N m 25000 rpm
    20，50 N m 20000 rpm
    100 N m 15000 rpm
    200 N m 12000 rpm
    500 N m 10000 rpm
    1000 N m 7000 rpm
    2000 N m 6000 rpm
    5000 N m 5000 rpm
    10000 N m 4000 rpm
  • Small starting torque
    The starting torque of the bearing in the UTMⅡ-0.05Nm is only 0.00001 Nm (0.03% FS).
    Actually, the effect of rotating friction can be negligible.
    • Smart system configuration with no external circuits needed



    Simultaneous detection of torque and rotating speed

    Real-time dynamic measurement is possible from torque and rotation pulse signals.

    Torque variation against angles is detected

    Equipped with an optional rotary encoder to the UTMⅡ, torque and angles are simultaneously monitored.
