Notice
During installation and when operating the transducer, please be aware of the maximum
parasitic forces/lateral forces (caused by oblique application), bending moments (caused
by eccentric force introduction) and torques, see Specifications section 10, and the maxi­
mum permissible load-carrying capacity of any (customer side) force application parts that
may be used.
Also note the maximum load-carrying capacity of the fittings, tension/compression bars,
bolts and knuckle eyes that are used.

Installing the U9C

7.3.1

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 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.
