7 MECHANICAL INSTALLATION
7.1 Important precautions during installation
S
Handle the transducer with care.
S
Note the requirements for the force application parts stated in the following sections
of this manual.
S
Welding currents must not be allowed to flow over 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 provides the highly flexible EEK ground cable for this
purpose, for example, that is screwed on above and below the transducer.
S
Make sure that the transducer cannot be overloaded.
WARNING
There is a danger of the transducer breaking if it is overloaded. This could endanger the
operating personnel of the equipment in which the transducer is installed.
Implement appropriate safety measures to avoid a force overshoot or to protect against
resulting dangers. The maximum possible mechanical stresses, especially the breaking
force
,
are noted in the specifications.
During installation and operation of the transducer, observe the maximum parasitic forces
- lateral forces, bending moments and torques, see technical data - and the maximum
permissible load capacity of the force application parts being used.
7.2 General installation guidelines
The forces to be measured must act on the transducer as accurately as possible in the
direction of measurement. Eccentric loads
,
resulting bending moments and lateral forces
can lead to measurement errors and destroy the transducer if the limit values are
exceeded.
Customers' constructional elements must meet the following conditions.
.
S
They must be sufficiently rigid so that they do not bend even under load
S
They must have sufficient hardness (40 HRC minimum)
S
They must be free of paint or other coatings
S
The upper and lower load application points must be parallel to each other
