The RST- Series is our low
range rotating torque sensors that are available
in eleven full scale ranges of 10 through 30K inch
pounds. The sensing element incorporates bonded
foil strain gages of the highest quality along
with coined silver slip ring and silver brushes
for data transmission. The WR2, Flexural Natural
Frequency, and Torsional Stiffness values as
stated in the Dynamic Characteristics box below,
are approximate and the tabulated data pertains to
the torque pickup only, and does not include the
effects of couplings or other rotating masses that
would be part of a dynamic system.
Our RSS Series rotating socket
wrench torque sensors are available in ranges from
10 ft-lbs. through 1000 ft-lbs. and provide
accurate measurements of bolt or nut wrenching
torques. These sensors are bi-directional so both
tightening and break-away torques can be measured.
Unlimited rotation of the ball bearing supported
sensor shaft allows monitoring of the total
fastening cycle. The sensing element incorporates
bonded foil strain gages of the highest quality,
along with coined silver slip rings and two silver
graphite brushes per ring for data
transmission.
The RTS Series torque
sensors were designed to fill the need for
accurate torque measurements below 62.5 in.lbs.
without giving up stiffness or sensitivity to
forces from other directions. They are
manufactured from sensor quality aluminum and
anodized for long-term durability. Bonded foil
strain gages and materials of the highest quality
are installed assuring high reliability. The four
bolt hole pattern with the use of our O.D. or I.D.
pilots on either end allows simple adaptation to
any application.

TMNR series
Feature:
TMNR type Torque meter is a
highly effective rotary transformer to transmit
the electric signal that the sensing point of
torque detected. Therefore, the steady
performance is gotten as for the measurement for
a long time, because driving side and the
measurement side are noncontact. It is used
for the instrumentation control only for the
measurement. It is possible to use it for not
only the torque measurement but also the
instrumentation control field, For instance,
control of stir power and kneading power in food
chemical industry etc., because of the efficient
rotary transformer adoption.
The horsepower measurement on
motors can be done, because the rotational speed
can be measured by installing rotation detector
(Options).

Specifications
TMNR-ME series
Feature:
TMNR-*ME type Torque meter can
measure the torque from the geostationary axis
to the high-speed spindle by the double bearing
adoption. As the strength is higher than the
standard model (TMNR type) both for radial and
thrust, and a direct coupling with a propeller
shaft etc. are more possible by making the
bearing double. Because the dropping lubricant
method is assumed to be a standard, the torque
measurement to which a heavy load hangs is
possible. (Please inquire for a grease
lubrication method).
It is possible to use it for
the test stand for not only the torque
measurement but also the instrumentation control
field , for instance, the car etc. because of
the efficient rotary transformer adoption.
Because the rotational speed
can be measured by installing the rotation
detector(option), the horsepower of the motor
output etc. can be measured.
