2.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in
serious injury or death, if not avoided.
Information
... points out useful tips, recommendations and information for effici-
ent and trouble-free operation.
WARNING!
... indicates a potentially dangerous situation that can result in burns,
caused by hot surfaces or liquids, if not avoided.
2.2 Intended use
WARNING!
Before installation, commissioning and operation, ensure that the
appropriate dierential pressure gauge has been selected in terms
of design and specic measuring conditions.
■
Check the compatibility with the medium of the materials subjec-
ted to pressure!
■
In order to guarantee the measurement accuracy and service life
specied, the corresponding load limits must be observed.
■
Only work on the gauge with the voltage disconnected.
▶Non-observance can result in serious injury and/or damage to
property.
Further important safety instructions can be found in the individual
chapters of these operating instructions.
The dierential pressure gauges of the DELTA-line product family are primarily
used for the monitoring and control of low dierential pressures where there are
high requirements in terms of one-sided overload and static pressure.
Typical markets for these products are the shipbuilding industry, process heating
technology, the heating, ventilation and air-conditioning industries, the water/
wastewater industry, and machine building and plant construction. For these, the
main function of the measuring instruments is the monitoring and control of lters,
compressors and pumps.

Classication per European pressure equipment directive
■
Instrument type: Pressure accessory without safety function
■
Media: Liquid or gaseous, group 1 (hazardous)
■
For maximum allowable pressure PS, see chapter 2.5 “Labelling / safety
marks”
■
Volume: < 0.1 l
The instrument must only be used with media which are not harmful to the wetted
parts over the entire operating range of the instrument. Any change in the state of
the matter or any decomposition of unstable media is not permitted.
Only use the instrument in applications that lie within its technical performance
limits (e.g. max. ambient temperature, material compatibility, ...).
→ For performance limits, see chapter 3 “Specications”.
The manufacturer shall not be liable for claims of any type based on operation
contrary to the intended use.
2.3 Personnel qualification
WARNING!
Risk of injury should qualication be insucient!
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 qualications
described below.
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel
who, based on their technical training, knowledge of measurement and control
technology and on their experience and knowledge of country-specic regu-
lations, current standards and directives, are capable of carrying out the work
described and independently recognising potential hazards.
2.4 Special hazards
WARNING!
For hazardous media such as oxygen, acetylene, ammable or
toxic gases or liquids, and refrigeration plants, compressors, etc., in
addition to all standard regulations, the appropriate existing codes
or regulations must also be followed.
