WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and
injuries.
▶
Refrain from unauthorised modifications to the instrument.
▶
Do not use the instrument within hazardous areas.
WARNING!
Physical injuries and damage to property and the environment
through exceeding the performance limits
Exceeding the performance limits can destroy the instrument and lead to
danger in the end-use application.
▶
Use the instrument only in applications within the technical performance
limits (→ for performance limits, such as derating (maximum current
supply at a corresponding medium temperature), see chapter 9 "Specifi-
cations").
▶
Any permanent operation in the overload range is not permitted. Above
the highest permissible operating pressure, up to the overload limit, the
gas density sensor is operating outside its specification. The overload
range is intended to prevent damage to the gas density 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 gas density sensor should not be used with abrasive or unstable
fluids, in particular not with hydrogen.
WARNING!
Risk of injury should qualification be insufficient
Improper handling can result in considerable injury and damage to property.
▶
The activities described in these operating instructions may only be
carried out by skilled personnel who have the qualifications described
below.
