Mounting the U9C

6.3.1

Mounting with tension and compression bars

In this mounting variant, the transducer is mounted with tension/compression
bars on a construction element and can measure tensile and compressive
forces. Alternating loads are also correctly recorded if the transducer is
mounted without axial play. For dynamic alternating loads, the upper and lower
threaded connectors must be pre-stressed to above the maximum force to be
measured and then locked in place.
1. Installation and locking with initial stress (for dynamic loading):
- Unscrew the locknut and screw on the threaded connector
- Pre-stress transducer to 110% operating load in tensile direction. The
transducer itself can be used to measure this force
- Hand-tighten the locknut
- Relieve load on transducer
Notice
If the torque for locking is shunted through the transducer, ensure that the
maximum torque is not exceeded. See specifications.
2. Mounting with locking
Screw on the load application parts and lock with a torque according to the
table below.
