Mounting with tension/compression bars

In this mounting variant, the transducer is mounted with tension/compression bars on a
construction element and can then be measured in the tensile and compressive direc­
tions. 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 operating load and then locked in place.
1. Installation and locking with initial stress (recommended mounting variant):
- Screw in the threaded connector
- Pre-stress transducer to 110 % operating load in tensile direction
- Hand-tighten the locknut
- Unload the transducer
2. Installation and locking with torque
- Screw in the threaded connector
- Tighten the locknut to the following torques:
Nominal (rated) force in kN
0.5 ... 1
2 ... 10
