Safety instructions
Use as machine elements
Force transducers can be used as machine elements. When used in this
manner, note that to favor greater sensitivity, force transducers were not
designed with the safety factors usual in mechanical engineering. Please refer
to the "Load-carrying capacity limits" section and the specifications.
Accident prevention
The prevailing accident prevention regulations must be taken into account,
even though the breaking force values in the destructive range are well in
excess of the full scale value.
Additional safety precautions
Force transducers cannot (as passive transducers or as a measurement chain)
implement any (safety-relevant) cutoffs. This requires additional components
and constructive measures, for which the installer and operator of the plant is
responsible.
In cases where a breakage or malfunction of the force transducer would cause
injury to persons or damage to equipment, the user must take appropriate
additional safety precautions that meet at least the applicable safety and
accident prevention regulations (e.g. automatic emergency shutdown, overload
protection, catch straps or chains, or other fall protection).
The electronic processor that processes the measurement signal should be
designed so that failure of the measurement signal cannot lead to secondary
failures.
General dangers of failing to follow the safety instructions
Force transducers are state-of-the-art and failsafe. Transducers can give rise
to residual dangers if they are mounted, installed, used and operated
inappropriately or by untrained personnel. Every person involved with setting
up, starting up, operating or repairing a force transducer must have read and
understood the mounting instructions and in particular the technical safety
instructions. The force transducers can be damaged or destroyed by non-
designated use of the force transducer or by non-compliance with the mounting
and operating manual, these safety instructions or other applicable safety
regulations (safety and accident prevention regulations of the Employers'
