Additional safety precautions
Force transducers cannot (as passive transducers) implement any (safety-relevant) cut­
offs. 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 pre­
cautions 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 partic­
ular 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' Liability Insur­
ance Association) when using the force transducers. A force transducer can break, partic­
ularly if it is overloaded. The breakage of a force transducer can cause damage to prop­
erty or injury to persons in the vicinity of the force transducer.
If force transducers are not used as intended, or if the safety instructions or specifica­
tions in the mounting and operating instructions are ignored, it is also possible that a
force transducer may fail or malfunction, with the result that persons may be injured or
property damaged (due to the loads acting on or being monitored by the force trans­
ducer).
The scope of supply and performance of the transducer covers only a small area of force
measurement technology, as measurements with (resistive) strain gage sensors presup­
pose the use of electronic signal processing. Equipment planners, installers and opera­
tors should always plan, implement and respond to the safety engineering considerations
of force measurement technology in such a way as to minimize residual dangers. Perti­
nent national and local regulations must be complied with.
Conversions and modifications
The design or safety engineering of the transducer must not be modified without our
express permission. Any modification shall exclude all liability on our part for any dam­
age resulting therefrom.
