Mechanical Installation

5.1 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 use a suitable low‐resistance
connection to electrically bypass the transducer. HBM provides the highly
flexible EEK ground cable for this purpose, for example. It can be 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.

5.2 General Installation Guidelines

The forces to be measured must act perpendicularly to the force washer.
Torsional and bending moments, eccentric loading and lateral forces may
produce measurement errors and destroy the transducer if limit values are
exceeded (see Specifications).
In the CLP series force washers, the maximum bending moment is dependent
on the loading with a force in the measurement direction. The following rule
applies: A force washer loaded with nominal (rated) force must not be
additionally loaded with a bending moment. This also applies to a force
washer where no force is acting in the measurement direction. The maximum
permissible bending moments can be found in the "Specifications" section, on
page 17.
The transducer needs to be pre‐stressed so that forces can be measured. We
recommend selecting a pre‐stressing value so that the sum of the pre‐stress
force and the force to be measured is equal to approximately half the nominal
(rated) force of the force washer. The force washer can be loaded with the
largest bending moment in this range. The minimum pre‐stress force must be
10% of the nominal (rated) force. The force washer itself can be used to
determine the pre‐stress force: The test certificate accompanying the
