Important precautions during installation

S
Handle the transducer with care.
S
Ensure that the force application parts mounted on the sensor are designed to
withstand the forces to be measured.
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. HBK offers the highly flexible EEK ground cable in various
lengths for this purpose, that is screwed on above and below the transducer.
S
Make sure that the transducer is not overloaded.
The cable fastening side of the transducer should always be connected directly with the
rigid customer-side force transfer area. Ensure that the cable is laid so that, where
possible, no force shunt is caused by the cable.
WARNING
If the transducer is overloaded, there is a risk that it might break. 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 safety measures to avoid overloads (also see the Specifications
section 10 on page 58) or to protect against resulting dangers.

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,
eccentric loading and the lateral forces themselves, may produce measurement errors
and destroy the transducer if limit values are exceeded.
Eccentric loads can lead to a bending moment load. The bending moment can be
calculated by multiplying the applied force by the eccentricity:

M = F*e
