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.
