Mounting With Mounted Force Application - HBM U10M Montageanleitung

U10M, U10S

5.6 Mounting with mounted force application

The U10M can also be ordered as an option with a mounted force application
bolt. The transducer can then measure axial forces in both the tensile and
pressure directions. Alternating loads are also correctly recorded if the trans-
ducer is mounted without axial play. For dynamic sustained loads, the upper
and lower threaded connectors must be pre-stressed to above the maximum
load with locknuts. This can be achieved using a suitable torque for nominal
(rated) forces up to 25 kN. Please use the torques in the table on Page 17.
Alternatively, and for higher nominal (rated) forces, pre-stressing can be im-
plemented by applying a force and then tightening the locknut, as is the when
mounting with a central internal thread.
Procedure
• Screw on the locknut.
• Screw on the force application part up to the retainer on the force
application bolt.
• Unscrew force application part two revolutions.
• Load the force transducer to 120% operating force (note limit forces).
• Hand-tighten locknut.
• Relieve the load on the transducer.
