Maximum moments and
off-axis loading
• Use extraneous load information to
determine if the sensor can withstand any
unavoidable off-axis loads and moments .
Extraneous load information can be found

factor
• An Extraneous how-to-guide can be

• Torsional stiffness is an indication of how
much torque will result in one radian of
angular deflection . The torsional stiffness
can be found on the sensor’s spec sheet .
• Note: To avoid damage when applying
torque, only constrain the flange attached to
the fastener .
