WARNING!
Physical injuries and damage to property and the environment through exceeding the perfor-
mance limits
Exceeding the performance limits can destroy the instrument and lead to danger in the end-use
application.

Only use the instrument in applications that lie within its technical performance limits.
→ For performance limits, such as derating (maximum current consumption at a corresponding
medium temperature), see chapter 9 "Specifications"
Any permanent operation in the overload range is not permitted. Above the highest operating
pressure permitted, up to the overload limit, the pressure sensor is operating outside its specifica-
tion. The overload range is intended to prevent damage to the pressure sensor, as part of a pressure
vessel system, during the pressure containment test.
The overload limit must never be exceeded, even when failures occur in the end-use application.
Loads above the overload limit can cause irreversible damage, which can lead, for example, to
permanent measuring errors.
The manufacturer or operator of the machine or plant in which the product is used must ensure the
compatibility of the materials of the wetted parts with the medium used.
The pressure switch should not be used with abrasive or unstable fluids, in particular not with
hydrogen.
