Notice
When locking, the tightening torque must not be shunted
through the transducer.
6.3.2

Mounting with direct connection

In this mounting variant, the transducer is mounted dir­
ectly on an existing construction element and can then
measure in the tensile and compressive directions.
Alternating loads are also correctly recorded if the trans­
ducer is mounted without axial play. For dynamic altern­
ating loads, the screw connected to the rigid force trans­
fer must be tightened with a torque of 15 Nm.
6.3.3

Mounting with knuckle eyes

Knuckle eyes prevent the application of torsional
moments on the transducer and also, when 2 knuckle
eyes are used, bending moments, together with lateral
and oblique loadings. Although if two knuckle eyes are
used, only tensile forces can be measured. Knuckle eyes
are suitable for use with quasi‐static loading (load cycles
v10 Hz). Pliable tension/compression bars should be
used for dynamic loads with higher frequencies (see
Section 6.3.1).
1. Installation of knuckle eyes and locking with initial
stress:
S Rotate the locknut back to the eye.
S Screw the knuckle eye completely into the transducer.
S Unscrew the knuckle eye 1 to 2 threads and align.
