Safety instructions
Use as a machine element
Force transducers can be used as machine elements. When used in this man­
ner, note that to favor greater sensitivity, force transducers were not designed
with the safety factors usual in mechanical engineering. Please refer here to
the section "Loading-carrying capacity limits", and to 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) implement any (safety-rele­
vant) 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 acci­
dent prevention regulations (e.g. automatic emergency shutdown, overload
protection, catch straps or chains, or other fall protection).
The electronics conditioning the measurement signal should be designed so
that measurement signal failure does not subsequently cause damage.
General dangers of failing to follow the safety instructions
The force transducers are state-of-the-art and failsafe. There may be dangers
involved if the transducers are mounted, sited, installed and operated inappro­
priately, or by untrained personnel. Every person involved 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 destroyed by non-designated use of the
force transducer or by non-compliance with the mounting and operating
instructions, these safety instructions or other applicable safety regulations (BG
safety and accident prevention regulations) when using the force transducers.
A force transducer can break, particularly in the case of overloading. The
