Do not use less than the starting torques M
overleaf, which should be routed through the transducer, in non-positive
contact.
When locking, make sure that the transducer signal changes by no more than
0.1 %.
In the case of transducers with nominal forces 20 kN..100 kN, you can also
lock as follows for tensile loading:
• screw in knuckle eyes
• load transducer with 10..20 % of the nominal force
• tighten the lock nut of the lower knuckle eye
Static loading can also − in addition to using knuckle eyes − be carried
axially to the transducer through hardened (40...44 HRc) pressure plates that
have been given a plane-parallel surface. The transducer support structure
must also have an inflexible, hardened and plane-parallel surface.
