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. 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.
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
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 safety measures to avoid overloads (see Specifications
in Chapter 123, Page 456) or to protect against resulting dangers.
6.2

General installation guidelines

The forces to be measured must act on the transducer as accurately as possi­
ble 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.
