Accident prevention
The prevailing accident prevention regulations must be taken into account,
even though the nominal (rated) force values in the destructive range are well
in excess of the full scale value.
Additional safety precautions
The force transducers cannot (as passive transducers) implement any (safety‐
relevant) cutoffs. This requires additional components and constructive mea
sures 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 appropri
ate additional safety measures that meet at least the requirements of applica
ble safety and accident prevention regulations (e.g. automatic emergency
shutdown, overload protection, catch straps or chains, or other fall protection).
The layout of the electronics conditioning the measurement signal should be
such that measurement signal failure does not cause damage.
General dangers of failing to follow the safety instructions
The force transducers are state‐of‐the‐art and reliable. Transducers can give
rise to residual dangers if they are incorrectly operated or inappropriately
mounted, installed and operated by untrained personnel. Every person in
volved with siting, 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 de
stroyed by non‐designated use of the force transducer or by non‐
compliance with the mounting and operating instructions, these safety instruc
tions or any other applicable safety regulations (BG safety and accident pre
vention regulations) when using the force transducers. Force transducers can
break, particularly in the case of overloading. The breakage of a force trans
ducer can also cause damage to property or injury to persons in the vicinity of
the force transducer.
If force transducers are not used according to their designated use, or if the
safety instructions or specifications in the mounting and operating instructions
are ignored, it is also possible that the force transducer may fail or malfunc
tion, with the result that persons or property may be affected (due to the loads
acting on or being monitored by the force transducer).
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 presuppose the use of electronic signal processing. In
addition, equipment planners, installers and operators should plan, implement
and respond to the safety engineering considerations of force measurement
