manufactured using state-of-the-art technology. All components are subject

to stringent quality and environmental criteria during production. Our manage-

ment 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 inst-

ructions 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 inst-

ructions 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 unautho-

rised modications to the instrument.

2. Safety

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 dierential pressure gauge has been selected in terms

of design and specic 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

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

property.

Further important safety instructions can be found in the individual

chapters of these operating instructions.

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 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.

Classication 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 “Specications”.

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 qualication be insucient!

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 qualications

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-specic 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.
