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 in­
staller 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 electronics conditioning the measurement signal should be designed so that mea­
surement signal failure cannot subsequently cause damage.
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. 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 when
using the force transducers. A force transducer can break, particularly in the case of over­
load. The breakage of a force transducer can cause damage to property or injury to per­
sons 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 piezoelectric force transducers 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. Comply
with pertinent national and local regulations.
Conversions and modifications
The design or safety engineering of the transducer must not be modified without our ex­
press permission. Any modification shall exclude all liability on our part for any damage
resulting therefrom.
Maintenance
The force transducers of the CFT+ series are maintenance free.
