Mounting with tension and compression bars

In this mounting variant, the transducer is mounted on a construction element
by means of tension/compression bars, and can measure tensile and
compressive forces. Alternating loads are also correctly recorded if the trans­
ducer 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 the transducer to 110% operating load in tensile direction. The
transducer itself can be used to measure this force
- Hand-tighten the locknut.
- Relieve the load on the 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.
