Mounting With Direct Bolted Connection; Mounting With Knuckle Eyes - HBM S9M Notice De Montage

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
20
50
Notice
When locking, the tightening torque must not be shunted through the transd­
ucer.
Mounting with initial stress is preferable to mounting with a defined tightening
torque.
7.3.2

Mounting with direct bolted connection

In this mounting variant, the transducer is mounted directly on an existing con­
struction element and can then measure 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 tightening torque for the
screws must be selected so that the screws are pre-stressed to above the
maximum operating load of the transducer. Comply with the tightening torques
and information provided in Section 7.3.1 when mounting using torque.
7.3.3

Mounting with knuckle eyes

Knuckle eyes prevent the application of torsional moments on the transducer
and also, when two knuckle eyes are used, bending moments, together with
lateral and oblique loadings. They are suitable for use with quasi-static loading
