Safety instructions
Use as a machine element
The load cells can be used as machine elements. When used in this manner, it
must be noted that, to favor greater sensitivity, the load cell is not designed
with the safety factors usual in mechanical engineering. Please refer here to
the section "Load carrying capacity limits" and to the specifications.
Accident prevention
The prevailing accident prevention regulations must be taken into account,
even though the maximum capacity values in the destructive range are well in
excess of the full scale value.
Additional safety precautions
Load cells cannot (as passive transducers) implement any (safety‐relevant)
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 load cells would cause injury
to persons or damage to equipment, the user must take appropriate additional
safety measures that meet at least the requirements of 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 measurement signal failure does not cause damage.
General dangers of failing to follow the safety instructions
Load cells are state‐of‐the‐art and reliable. There may be risks involved if the
transducers are mounted, sited, installed and operated inappropriately, or by
untrained personnel. Everyone involved with siting, starting up, operating or
repairing a load cell must have read and understood the mounting instructions
and in particular the technical safety instructions. The load cells can be
damaged or destroyed by non‐designated use of the load cells or by
non‐compliance with the mounting and operating instructions, these safety
instructions or any other applicable safety regulations (BG safety and accident
prevention regulations) when using the load cells. Load cells can break,
particularly in the case of overloading. The breakage of a load cell can also
cause damage to property or injury to persons in the vicinity of the load cell.
