5.1 Precautions before commissioning
■
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
threaded 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
■
Torsional moments, eccentric loads and transverse loads or lateral forces cause
measuring errors and may permanently damage the tension/compression force
transducer.
■
Incorrect loads can cause permanent damage, resulting in a zero signal deviation in
the unloaded state.
▶
With the installation of the tension/compression force transducer, the installation
position and the load direction must be considered.
▶
Torsional and shear forces must be avoided. Transverse loads and lateral forces
also include the corresponding components of the measurands that are introduced
slanted.
▶
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 mechanical overload.
▶
If high shear forces or lateral forces are to be expected, the use of swivel heads is
recommended.
▶
The supplied counter nuts for model F2226 must never rest on the deformation
element. A gap of at least 0.5 mm must be provided.
▶
With models F2220 and F2221, the device must not touch the deformation element.
