2.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury or
death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or
damage to property or the environment, if not avoided.
DANGER!
... identifies hazards caused by electrical power. Should the safety instructions not
be observed, there is a risk of serious or fatal injury.
WARNING!
... indicates a potentially dangerous situation in the hazardous area that results in
serious injury or death, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result in burns, caused by hot
surfaces or liquids, if not avoided.
Information
... points out useful tips, recommendations and information for efficient and trouble-
free operation.
2.2 Intended use
Mechanical differential pressure measuring instruments are used for the display of levels on
closed vessels, particularly in cryotechnology. Depending on the version, integrated trans-
mitter electronics can be used to output an electrical output signal for control. An optionally
mounted valve manifold facilitates commissioning and maintenance of the instrument. Optio-
nally, the working pressure can be measured additionally with a pressure gauge or a pressure
sensor.
The instrument offers many application possibilities, in particular for gaseous and liquid
gases, and also for media that are non-aggressive, not highly viscous and non-crystallising.
Only use the instrument in applications that lie within its technical performance limits (e.g.
temperature limits, material compatibility, ...).
