Torque Sensors
The principal axis of a transducer is normally the
M
Z
axis. The M
Z
axis will also be the axis of radial
symmetry or axis of rotation. In the event there is no
clearly defined axis, the following preference
system will be used z,x,y.
2.0 SAFETY INFORMATION
Failure of the sensor structure or fasteners used in
its installation may cause personal injury and
equipment damage. To prevent structure failure,
review the extraneous load limits listed on the
specification sheet supplied with this manual.
Extraneous load limits are extraneous side force,
thrust and bending moment that may be applied
without electrical or mechanical damage to the
torque sensor. Do not exceed moment (W x S) or
shear (W) whichever attained first. Measurement
inaccuracy and structure damage may result. Install
the sensor in a manner that minimizes these loads.
In addition, review data from manufacturers of
fixtures and fasteners used in the sensors
installation to determine if failure might occur due
to these loads.
3.0 MECHANICAL INSTALLATION
Refer to the outline drawing supplied with this
manual for specific outline dimensions and
installation details for your particular model. The
specification is also included to provide details of
the sensor
’
s characteristic properties.
Shown below are some of the standard reaction
torque sensor configurations offered by the
Force/Torque Division.
