Mechanical installation

5.1 Important precautions during installation

• Handle the transducer gently
• Do not overload the transducer
• 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, for example, provides the highly
flexible EEK ground cable, which can be screwed on, both above and
below the transducer.
WARNING
Additional safeguards must be provided if there is a risk that
overloading the transducer may cause it to break, which
could put people at risk.

5.2 General installation guidelines

The forces to be measured must act on the transducer as accurately as
possible in the direction of measurement. Torsional and bending moments,
eccentric loading and lateral forces may produce measurement errors and
destroy the transducer, if limit values are exceeded (see Specifications).

5.3 Installation for compressive loading

The transducer is bolted directly by the ring‐shaped mounting surfaces on the
top and bottom of the force transducer to a stiff, fully bearing structural
element (such as a profile, cover or plate). With this type of installation, the
transducer can measure axial forces in the pressure direction.
• For exact positioning, the transducer is fitted with centering aids on the
upper and lower mounting surfaces.
• To achieve calibration accuracy over the entire force range, the roughness
of the support surfaces must be Ra v 0.8 μm and the hardness,
> 40 HRC.
• The support surfaces must be thoroughly cleaned before mounting.
