2. Design and function
2. Design and function
The compression force transducer is designed for measuring static and dynamic
compression forces.The compression force transducer consists of a measuring spring
on which strain gauges are applied.The measuring spring is made of 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 transducer circuit includes correction and compensation resistors to eliminate
unwanted effects on the zero signal and characteristic value.

Force transducer for measuring compression forces, for example in presses.The
product is designed for use both outdoors and inside buildings.
Compression force transducers can measure forces in one direction. The measured
force is output as an electrical signal. These devices are designed for operation in
industrial environment. In other environments, e.g. residential or commercial, they may
interfere with other equipment. In this case, the operator may be required to implement
appropriate measures.
Only use the compression force transducers in applications that are within the technical
performance limits (e.g. max. ambient temperature, material compatibility, etc.). For
performance limits, see chapter 9 “Technical data”.
The compression force transducers are not approved for use in explosive areas or for
safety applications.

4. Transport, packaging and storage
4. Transport, packaging and storage
4.1 Transport
Check the 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
transport and mounting. Load impacts during transport (e.g. hitting a hard surface) can
lead to permanent damage, resulting in measured 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: -20 ... +80 °C [-4 … +176 °F]
■
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.

5. Commissioning, operation
5. Commissioning, operation
5.1 Precautions before commissioning
■
Compression force transducers are sensitive measuring instruments and must be
handled with appropriate care.
■
With the commissioning of compression force transducers, make sure they are on a
level, clean and grease-free contact surface.The flatness shall be 0.02 mm [0.0008 in].
■
The contact surface must have a hardness of at least HRC 43, be ground or lapped,
have a surface roughness of Rz 4 and must not bend under load.
5.2 Mounting instructions
CAUTION!
Damage to the instrument through improper commissioning
Torsional torques, eccentric loading and transverse loading or lateral
forces cause measured errors and may permanently damage the
compression force transducer. Incorrect loading can lead to permanent
damage resulting in a zero point offset in the unloaded state.
▶
The force introduction must always be applied centrally to the crowned
surface of the compression force transducer.
▶
Torsional and transverse forces must be avoided. Transverse loading
and lateral forces also include the corresponding components of the
measurands that are introduced slanted.
▶
During installation of the compression force transducer, the output
signal (force value) must always be monitored to avoid mechanical
overloading.
▶
The compression force transducer should only be loaded with the
intended type of load-bearing and in the intended force direction.
▶
Overloading must be excluded at all times.
▶
The rated temperature range must be observed.Temperature-related
measured errors must be excluded.

Contact surface
5.4 Electrical connection
A shielded, low-capacitance measuring cable is attached to the force transducer.
To prevent interferences from coupling into the system, observe the following
information:
■
A cable amplifier can be fitted optionally.
■
Ground the shield of the measuring cable.
■
Avoid stray fields of transformers, motors and contactors.
■
When using extensions, only shielded and low-capacitance cables should be used.
The permitted maximum and minimum lengths of cable are defined in ISO 11898-2.
Care should be taken also to ensure a high-quality connection of the shielding.
■
Do not install measuring cables in parallel to 3-phase-current cables and control
cables.
■
Transducers, amplifiers and processing or display units must not be grounded
several times.
The pin assignments of the cable and the cable amplifier (fitted optionally) can be found
on the product label.
