Additional safety precautions
Strain 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 strain transducer would
cause injury to persons or damage to equipment, the user must also take ap­
propriate safety measures that meet at least the requirements of applicable
safety and accident prevention regulations (e.g. automatic emergency shut­
down, overload protection, 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
Strain 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 strain transducer must
have read and understood the mounting instructions and in particular the
technical safety instructions. Strain transducers can be damaged or destroyed
by non‐designated use or by non‐compliance with the mounting and operating
instructions, these safety instructions or any other applicable safety regula­
tions pertinent to the handling of strain transducers. Strain transducers can
break in two, particularly if they are overloaded. If a strain transducer breaks
apart, it may injure any persons in the surrounding area or damage equip­
ment.
If strain transducers are not used as designated, or if the safety instructions or
specifications in the mounting‐ and operating instructions are ignored, it is
also possible that the strain transducer may fail or malfunction, with the result
that persons could be injured or equipment damaged (due to the loads acting
on or being monitored by the strain transducer).
The scope of supply and performance of the transducer covers only a small
area of measurement technology, as measurements with (resistive) strain
gage sensors presuppose the use of electronic signal conditioning. In addi­
tion, equipment planners, installers and operators should plan, implement and
respond to safety engineering considerations in such a way as to minimize re­
sidual dangers.
