A longtime dream, a slip-ring-less rotating torque meter, UTMⅡ , has
just become available. We developed it as a high performance sensor
for embedded applications. Of course, it is also perfect for general
dynamic torque measurement. This is our masterpiece, which has
1/10000-resolution, outstanding zero-point stability and 1kHz-bandwidth
(sampling frequency of 6kHz).
UNIPULSE was established by several young engineers in 1970 and has
specialized in industrial measurement since that time. We have developed
a lot of unique products and expanded our own market. Though we
had wished to make a high-performance torque meter for 40 years, we
couldn't do so because miniaturization of electronics was not possible.
However, we have finally succeeded in developing a rotating torque
meter, UTMⅡ , by adopting small advanced electronic components and
integrating our own technologies related to precision machining, strain
gauge technology and electronics.
UTMⅡ has a range of 16 models (0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50,
100, 200, 500, 1000, 2000, 5000Nm).
UTMⅡ withstands overload of 500% and, with its internal circuits all
insulated, operates stably even in a high noise environment. The models
ranging from 0.05 to 10Nm guarantee operation at the max. speed of
25000rpm.
All the models of UTMⅡ output a 4-pulse rotation detection signal per
rotation.
A 2000C/T optical encoder can optionally be built in models
ranging from 0.05 to 10Nm. This encoder is used mainly for measuring
torque variation (physical sensory test) with angular position.
Key
grooves are optionally available for models ranging from 5 to 5000Nm.
For measurement signal voltage, full-scale values of normal/reverse
rotations are calibrated to ± 5.0000V before shipping.
We hope you are looking forward to our future products.

A new series
High-speed response of cut-off frequency 1kHz (sampling frequency of 6kHz).
This series can be used for not only fast process monitoring but also torque feedback.
Safe overload of 500%
1, 2 and 5-line capacities are standardized from 0.05Nm to 5000Nm.
Rotating speed increased from 1 pulse/rotation to 4 pulses/rotation.
Measurement accuracy in the low-speed rotation range is improved.
Power system and signal system are insulated to dramatically reduce noise influences.
1/10000 resolution
Outstanding zero-point stability
25,000rpm supported (up to 10Nm）

Overview
Principle of UTMⅡ
UTMⅡ adopts strain gauges for detecting torsional strain, which is converted into an electric signal by a strain
amplifier fixed on the rotating shaft. Electric power for the rotary electronics is supplied continuously through
a wireless power system originally developed by UNIPULSE. Both the power supply to rotating electronics and
detected electronic signals are wireless, and the rotating electronics and main frames have no mechanical contacts
except for bearings.

Compact and easy to install
High accuracy and stability
The six models (0.05, 0.1, 0.2, 0.5, 1, 2Nm) are
compact and light: 54W × 50H × 40Dmm in size,
200g or less in weight.
1/10000 resolution with outstanding zero stability.
Even small torque variations can be detected by
UTMⅡ .
Maintenance-free
Small starting torque
No slip-ring.
The lifetime of UTMⅡ is mainly determined by the
lifetime of bearings.
The starting torque of the bearing in the
UTMⅡ -0.05Nm is only 0.00001Nm (0.03 %FS).
Actually, the effect of rotating friction can be
negligible.

Coupling
What’ s coupling?
UTMⅡ adopts strain gauges for measuring torsional strain on the shaft. The shaft is designed to withstand any
disturbing stress induced by radial or thrust forces. However, radial/thrust overloads will not only result in measurement
error but also heating-up of the bearings and/or irreversible distortion or fracture of UTMⅡ . Typical misalignments,
radial misalignment, angular misalignment, and endplay are shown in the figure below. Remaining misalignments
between the UTMⅡ shaft and drive/load shafts induce radial and thrust forces. Hence couplings are required to absorb
these disturbing forces and improve smoothness of rotating and accuracy. Allowance levels of the misalignments are
dependent on the combination of the range of UTMⅡ and couplings; thus fine adjustment will be needed for actual
usage.
Radial misalignment
Angular misalignment
Endplay
Recommended coupling
Coupling
We strongly recommend rubber couplings shown in the right-hand
side photograph (Correspondent couplings are indicated by
● in the following table). Rubber coupling is composed of two rigid
parts connected to the axes with rubber joining the two parts.
No backlash, well rotation balance and excellent damping of
vibration are the features of rubber coupling, and thus they are
the most suitable couplings for UTMⅡ . If you can not choose
rubber couplings, please select single disk couplings. If you use
multiple double disk couplings or slit type couplings on the axis,
unexpected vibration may occur because UTMⅡ is suspended by
springs. Unexpected vibration reduces accuracy and results in
damage on UTMⅡ in the worst case.
How to use coupling
UTMⅡ shafts are connected to drive-side and load-side shafts with rubber couplings as shown in the below. If the load
and driving devices have bearing internally, the bearings in the figure are unnecessary.
Main frame of UTMⅡ should be fixed loosely to the base.

6RIWPDWHULDOEORFN
OLNHXUHWKDQHIRUP
5XEEHUFRXSOLQJ
Please minimize the torque fluctuation synchronized to rotation and adjust the misalignments carefully.
21
Warning in high rotating speed
Rotating balance adjustment is needed for torque measurement over 3000rpm rotating speed. Unbalance of rotating
body induces vibration, which causes damage on UTMⅡ or coupling. Before conducting high speed operation, do the
balance adjustment carefully. We do not recommend key groove option for high speed applications.
Prohibition
・Do not use Oldham coupling. UTMⅡ will come off the original position, and UTMⅡ or other devices will be damaged.
・Do not use double disk coupling or slit type coupling. Unexpected resonant vibration occurs, and it generates overloads
or damages to UTMⅡ .
