Load limits 4) Unit Value
33 Maximum measurable torque % 110
34 Maximum torque, related to nominal torque % 300
35 Ultimate torque % 500
36 Maximum load of key stone (Application factor 1,5) % 180 200 200
4) Based on the non-contact measurement principle the torque sensor is quite insensitive to bending
and shearing forces. Self-aligning couplings are recommended in case of dynamic loads.
