Heat conductance via the stator base plate necessary over 70C. The temperature of the base plate must not exceed 85C.
Each type of irregular stress (bending moment, lateral or longitudinal force, exceeding nominal (rated) torque) can only be permitted up to
its specified static load limit, provided none of the others can occur at the same time. If this condition is not met, the limit values must be
reduced. If 30% of the limit bending moment and lateral limit force occur at the same time, only 40% of the longitudinal limit force is
permissible and the nominal (rated) torque must not be exceeded. The permissible bending moments, longitudinal forces and lateral forces
can affect the measurement result by approx. 1 % of the nominal (rated) torque. The load limits only apply for the nominal (rated)
temperature range. At temperatures <10C, the load limits must be reduced by approx. 30% (viscosity reduction).
10) The data refer to static loading of the measuring body; note the screw connection!
11) The nominal (rated) torque must not be exceeded.
