Mechanical installation

3.1 Important precautions during installation

 Handle the transducer with care.
 Welding currents must not be allowed to flow over the transducer. If there is
a risk that this might happen, you must provide 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.
 Make sure that the transducer cannot be 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.
Implement appropriate safety measures to avoid overloads or to protect
against the resulting dangers.
NOTE
Load cells are precision measuring elements and need to be handled
carefully. Dropping or knocking the transducer may cause permanent
damage. Make sure that the transducer cannot be overloaded, including while
it is being mounted.

3.2 Mounting

Attach the load cells at the mounting holes and apply load to the other end.
