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 17 models (0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50,
100, 200, 500, 1000, 2000, 5000, 10000Nm).
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.
An optical encoder can optionally be built in models ranging
from 0.05 to 50Nm. This encoder is used mainly for measuring torque
variation (such as a physical sensory test) with angular position.
Key
grooves are optionally available for models ranging from 5 to 10000Nm.
Square drive option is now available in 100Nm and 500Nm capacity for
use with nut runners. Moreover, UTMV series, a rotating torque sensor
with degree of protection equivalent to IP65 , is now available to meet
users' needs for use in harsh environment. UTMV series is available in
10 capacity range: 0.1, 0.5, 1, 5, 10, 50, 100, 500, 1000, and 5000Nm
capacity. 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.

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. The detected torque signal is converted into a digital
signal, and it is transmitted to the main-frame electronics via a light signal. The rotating shaft is suspended with
only two small bearings, resulting in very low rotational friction.

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 .
Small starting torque
Maintenance-free
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.
No slip-ring.
The lifetime of UTMⅡ is mainly determined by the
lifetime of bearings.

Coupling
What’ s coupling?
UTMⅡ/UTMV 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/UTMV. Typical misalignments,
radial misalignment, angular misalignment, and endplay are shown in the figure below. Remaining misalignments
between the UTMⅡ/UTMV 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/UTMV and couplings; thus fine adjustment will be needed for
actual usage.

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/UTMV. 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/UTMV is
suspended by springs. Unexpected vibration reduces accuracy and
results in damage on UTMⅡ/UTMV in the worst case.
How to use couplings
UTMⅡ/UTMV 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.
A soft block made of urethane and on should be put between main frame of UTMⅡ/UTMV and base (to hold the main
frame of UTMⅡ/UTMV loosely).

Please minimize the torque fluctuation synchronized to rotation and adjust the misalignments carefully.
Warning in high rotating speed
In case UTMⅡ/UTMV is used at a high rotational speed, dynamic balance needs to be adjusted in addition to alignments.
If shaft is unbalanced, vibration will be caused at high rotational speed due to resonance, which, in turn will damage
UTMⅡ/UTMV and couplings. Please adjust the balance carefully, increasing the rotational speed gradually. Key groove
option is not recommended if UTMⅡ/UTMV is used at high rotational speed.

Prohibition
・Do not use Oldham coupling. UTMⅡ/UTMV will come off the original position, and UTMⅡ/UTMV or other devices
will be damaged.
・Do not use double disk coupling or slit type coupling. In case a slit type or double disc type coupling is used on one
end of shaft, please mount and fix the body of UTMⅡ/UTMV on a fixture or stand. Otherwise, resonant vibration
may occur, which, in turn, may cause overload and damages on UTMⅡ/UTMV.
Coupling correspondence table
Recommended couplings are indicated in the below table.

Connect to +24V power supply.
Voltage range must be
within +24V plus-minus 15%.
Use a power supply that can stably
operate with a small load since the
consumption current is 100mA or less
(20Nm to 500Nm: 150mA, 1000Nm to 10000Nm: 160mA）.
This is signal output. The signal is
adjusted to 0V for no-load
and 5V for full scale.
The minimum resistant is 2k Ω .

Precautions
Possibility of overloads during setup
Protection against water and condensation
If one side of shaft (either "Drive" or "Load" side)
is fixed during setup, excessive torque above rated
capacity may be applied to shafts unintentionally.
Please pay extra care especially for those types with
low rated capacity.
UTM Ⅱ /UTMV is not waterresistant, so please take
measures to avoid water
damage. Also, do not use the
product under dew-condensing
condition.
Overload due to resonance vibration
Alteration of shafts
Never make alteration to shafts
of UTMⅡ/UTMV (by machining) ,
as it will affect the accuracy of the
sensor.
In case UTM Ⅱ /UTMVis used
with device causing vibration,
overloads may be caused due
to resonance vibration.

Calibration of UTMⅡ/UTMV
1DWLRQDO,QVWLWXWHRI$GYDQFHG
,QGXVWULDO6FLHQFHDQG7HFKQRORJ\$,67
For calibrating torque meter, pure torque must be applied to the torque meter.
The equipments for the calibration are designed to eliminate disturbing force and
transmit the pure torque to UTMⅡ/UTMV. Because UTMⅡ and UTMV are available in
wide capacity range (0.05-10000Nm for UTMⅡ and 0.1-5000Nm for UTMV), different
calibration tools (designed and built in-house) are used for different capacity ranges.
The traceability diagram of UTMⅡ/UTMV is shown on the right. UTS series are non-rotary
torque sensors calibrated at AIST with the national standard torque generator, and those
are used as calibration masters for calibration of torque meters at our facility. With those
UTS series, UTMⅡ and UTMV torque meters (products) are calibrated.

＜ Traceability diagram
for UTMⅡ/UTMV ＞
Pictures below show calibration equipment with UTS-10000Nm (calibration master for 10000Nm capacity). A calibrated
torque meter and the calibration master (UTS) are directly connected, and the one side of the shaft is fixed. The other
side of the shaft is connected to a reduction gear, and a servo motor is used as an actuator to apply torque on the
connected shafts. The same torque is applied to the calibration master (UTS) and the calibrated product, and outputs
(voltage) from the calibration master and the products are measured and compared for calibration.

Rotational characteristics of UTMⅡ/UTMV
As the rotation speed goes up, the bearing
friction also increases like the graph on right. The
condition of bearing (installation, frequency of
use. , temperature, etc...) also affects the bearing
friction.
&KDQJHLQQRORDGRXWSXWFDXVHG
E\WKHEHDULQJIULFWLRQ‫ق‬٫)6‫ك‬
The error at the elevated rotation speed is
mainly originated from rotational friction of the
bearings and the distortion of the rotating shaft by
centrifugal force.
&:
&&:
5RWDWLRQVSHHGUSP
Combination of those contributing factors for
errors cause the fluctuation of no-load voltage
output corresponding to rotation speed.
Characteristics of UTMⅡ/UTMV
Also, centrifugal force could cause deformation
of spring elements, affecting the output like the
graph on right. The degree of error is related to
rotation speed, and it is reproducible. Degree of
change in output caused by deformation of spring
element is different for each product depending on
how symmetrically strain gauges are mounted on
the shaft.
