3. Safety
Tension links for measuring tension forces, for example in cranes.The product is
designed for use both outside and inside of buildings.
Tension links can measure forces in only one direction.The measured force is output
as an electrical signal.These devices are designed for operation in an industrial
environment. In other environments, e.g. residential or commercial, they may interfere
with other equipment. In this case, the operator may be required to implement
appropriate measures.
Only use the tension links in applications that are within the technical performance limits
(e.g. max. ambient temperature, material compability, etc.). For performance limits, see

Only the tensions links of models F73C1, version 1, are approved for use in hazardous
areas! For Ex instruments, please note the additional information to this operating
instruction (article number 14537280). For an overview, see the table on page 7.
The tensions links are designed exclusively for the intended use which is described here
and may only be used accordingly. Claims of any kind due to improper use are excluded.
