mitter has been selected in terms of measuring range, design and specic measuring conditions.

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 submersible pressure transmitter is used to convert hydrostatic pressure into an electrical signal.

The instrument is suitable for operation within an ambient temperature range from -10 ... +50 °C.

The instrument has been designed and built solely for the intended use described here, and may only be used

accordingly.

14075012.03 03/2018 EN/DE/FR/ES

The technical specications contained in these operating instructions must be observed. Improper handling or opera-

tion of the pressure transmitter outside of its technical specications requires the instrument to be taken out of service

immediately and inspected by an authorised WIKA service engineer.

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 experience and knowledge of country-specic regulations, current standards and

directives, are capable of carrying out the work described and independently recognising potential hazards.

Special operating conditions require further appropriate knowledge, e.g. of aggressive media.

2.3 Special hazards

WARNING!

For hazardous media such as acetylene, ammable or toxic gases and liquids, etc., in addition to all

standard regulations, the appropriate existing codes or regulations must also be followed.

WARNING!

Residual media in dismounted submersible pressure transmitters can result in a risk to persons, the

environment and equipment.

Take sucient precautionary measures.

Do not use this instrument in safety or emergency stop devices. Incorrect use of the instrument can result in

injury.

4. Design and function

4.1 Description

The prevailing pressure is measured at the sensor element through the deformation of a diaphragm. By supplying

power, this deformation of the diaphragm is converted into an electrical signal.The output signal from the pressure

transmitter is amplied and proportional to the prevailing pressure.

4.2 Scope of delivery

Cross-check scope of delivery with delivery note.

5. Transport, packaging and storage

5.1 Transport

Check the submersible pressure transmitter for any damage that may have been caused by transport.

Obvious damage must be reported immediately.

5.2 Packaging

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site, sending for

repair).

5.3 Storage

Permissible conditions at the place of storage:

Storage temperature: -30 ... +80 °C

Mount the protection cap for storing the submersible pressure transmitter, so that the diaphragm will not be damaged.

Avoid exposure to the following factors:

■

Direct sunlight or proximity to hot objects

■

Mechanical vibration, mechanical shock (putting it down hard)

■

Soot, vapour, dust and corrosive gases

■

Humid or wet environment

■

Potentially explosive environments, ammable atmospheres

Store the submersible pressure transmitter in its original packaging in a location that fulls the conditions listed above.

If the original packaging is not available, pack and store the instrument as described below:

1. Wrap the instrument in an antistatic plastic lm.

2. Place the instrument along with shock-absorbent material in the packaging.

3. If stored for a prolonged period of time (more than 30 days), place a bag containing a desiccant inside the packaging.

WARNING!

Before storing the instrument (following operation), remove any residual media.This is of particular

importance if the medium is hazardous to health, e.g. caustic, toxic, carcinogenic, radioactive, etc.
