MECHANICAL INSTALLATION

7.1

Important precautions during installation

S
Handle the transducer with care.
S
Comply with the requirements for the structural elements connected to the sensor, as
specified in chapter 7.2.
S
Welding currents must not be allowed to flow through the transducer. If there is a risk
that this might happen, you must use a suitable low-ohm connection to electrically
bypass the transducer. HBM offers the highly flexible EEK ground cable in various
lengths for this purpose, which can be screwed on above and below the transducer.
S
Make sure that the transducer is not overloaded.
WARNING
There is a danger of the transducer breaking if it is overloaded. This can cause danger for
the operating personnel of the system in which the transducer is installed, as well as for
people in the vicinity.
Implement appropriate safeguards to avoid a force overshoot (see also section 10
"Specifications", page 15) or to protect against any dangers that may result.
7.2

General installation guidelines

The forces to be measured must act on the transducer as accurately as possible in the
direction of measurement. Torques, bending moments resulting from lateral force, eccen­
tric loading and the lateral forces themselves, may produce measurement errors and
destroy the transducer, if limit values are exceeded.
Notice
When installing and operating the sensor, make sure that there is no extreme misalignment
or eccentric force application.
Load is applied via the spherical load button on top of the force transducer.
The structural component that applies the force to the convex load application part must
be ground and have a hardness of at least 40 HRC.
The substructure must be capable of absorbing the force to be measured. Remember
that the rigidity of the overall system depends on the stiffness of the force application
part and the substructure. Please also note that the substructure must ensure that force
always has to be applied to the transducer vertically, i.e. there must be no inclination,
even under full load.
