have been designed and manufactured using state-of-the-art technology.
All components are subject to stringent quality and environmental criteria
during production. Our management systems are certied to ISO 9001 and
ISO 14001.
■
These operating instructions contain important information on handling the
instrument. Working safely requires that all safety instructions and work
instructions are observed.
■
Observe the relevant local accident prevention regulations and general safety
regulations for the instrument's range of use.
■
The operating instructions are part of the product and must be kept in the
immediate vicinity of the instrument and readily accessible to skilled personnel
at any time.
■
Skilled personnel must have carefully read and understood the operating
instructions prior to beginning any work.
■
The manufacturer's liability is void in the case of any damage caused by
using the product contrary to its intended use, non-compliance with these
operating instructions, assignment of insuciently qualied skilled personnel
or unauthorised modications to the instrument.
■
The general terms and conditions contained in the sales documentation shall
apply.

2. Safety
2. Safety
WARNING!
Before installation, commissioning and operation, ensure that
the appropriate dierential pressure gauge has been selected
in terms of measuring range, design and specic measuring
conditions.
Check the compatibility with the medium of the materials
subjected to pressure!
In order to guarantee the measuring accuracy and long-term
stability specied, 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
the equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The dierential pressure gauges of the DELTA-line product family are primarily
used for the monitoring and control of low dierential pressures where there are
high requirements in terms of one-sided overpressure 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.
The instrument has been designed and built solely for the intended use described
here, and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on operation
contrary to the intended use.

2.2 Personnel qualication
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage
to equipment.
The activities described in these operating instructions may only
be carried out by skilled personnel who have the qualications
described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical
training, knowledge of measurement and control technology and on their experi-
ence and knowledge of country-specic regulations, current standards and direc-
tives, are capable of carrying out the work described and independently recognis-
ing potential hazards.
2. Safety
2.3 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.
WARNING!
Residual media in dismounted measuring instruments can result in
a risk to persons, the environment and equipment.
Take sucient precautionary measures.
WARNING!
The maximum surface temperature of the instrument may not
exceed the ignition temperature of ammable media.
Take sucient precautionary measures.
