U2B installation for tensile and compressive loading

The transducers can measure axial forces in torsional as well as compressive
directions. Alternating loads are also captured perfectly. For this purpose the
transducer must be installed without axial play. For dynamic sustained loading
the upper and lower threaded connectors must be pretightened with lock nuts
to more than the maximum load. For this purpose tighten the lock nuts fully
under nominal load in the tensile direction. If a lock-nut is used, the torque
must on no account be conducted through the transducer.
