Eccentric loads can lead to a bending moment load. The bending moment can
be calculated by multiplying the applied force with the eccentricity:

Parasitic forces and torques
Notice
When installing and operating the transducers, please note the maximum para
sitic forces - lateral forces (due to oblique application), bending moment (due to
eccentric force application) and torques, see specifications in Chapter 9, and
the maximum permissible loading capacity of the force application parts used
(possibly provided by the customer).
Please also note the maximum loading capacity of the mounting parts used
and of the tension/compression bars, screws and knuckle eyes.
