2.2 Description
The tension/compression force transducer is designed for measuring static and dyna-
mic tension/compression forces.The tension/compression force transducer consists
of a measuring spring on which strain gauges (SGs) are applied.The measuring body
is made of steel or corrosion-resistant stainless steel and is elastically deformed by a
tension/compression force introduced in the force direction.The resulting mechanical
tensions are measured by the strain gauges and output as an electrical output signal.
The strain gauges are arranged so that two of them are tensioned and the other two
are compressed when a force is applied to the transducer. The pick-up circuit includes
correction and compensation resistors to eliminate unwanted eects on the zero signal
and characteristic value.

4. Transport, packaging and storage
4. Transport, packaging and storage
4.1 Transport
Check the tension/compression force transducer for any damage that may have been
caused by transport. Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during
internal transport, proceed carefully and observe the symbols on the
packaging.
▶
With internal transport, observe the instructions in chapter 4.2
“Packaging and storage”.
As precision measuring instruments, transducers require careful handling during trans-
port and mounting. Load impacts during transport (e.g. hitting a hard surface) can lead
to permanent damage, resulting in measuring errors in the subsequent measuring
operation.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change
in installation site, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: See chapter 9 “Specifications”
■
Humidity: 35 ... 85 % relative humidity (non-condensing)
Avoid exposure to the following factors:
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Dust, dirt, and other objects may not be deposited in such a way that they form a
force shunt with the measuring spring, since this will falsify the measuring signal.

■
Tension/compression force transducers are sensitive measuring instruments and
must be handled with appropriate care.
■
Before installing the tension/compression force transducer, check whether the threa-
ded bores of the mounting position have been executed dimensionally accurately,
thus guaranteeing problem-free mechanical installation of the tension/compression
force transducer.
■
Before installation, make sure that any drilling chips have been removed from the
threaded bores.
5.2 Mounting instructions
CAUTION!
Damage to the instrument through improper installation
■
With the installation of the force transducer, the installation position and
the load direction must be considered.
■
Torsional and transverse forces must be avoided.Transverse loads
and lateral forces also include the corresponding components of the
measurands that are introduced slanted.
■
Torsional moments, eccentric loads and transverse loads or lateral
forces cause measuring errors and may permanently damage the
tension/compression force transducer.
■
The installation of the tension/compression force transducer must not
be made with any violent force.
■
During installation of the tension/compression force transducer, the
output signal (force value) must always be monitored to avoid mechani-
cal overload.
■
When subjected to loads in other devices, other than those planned
in the application, a change in the zero signal may result in permanent
damage.
■
Do not use the tension/compression force transducer as a climbing aid.
