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.

6. Commissioning, operation
WARNING!
Observe the working conditions in accordance with chapter 3 “Specications”.
CAUTION!
Prior to commissioning, the submersible pressure transmitter must be subjected to a visual inspection.
■
Leaking uid is indicative of damage.
■
Only use the submersible pressure transmitter if it is in perfect condition with respect to safety.
6.1 Mechanical mounting
The protection cap protects the internal diaphragm from damage. Remove the protective cap if the medium is viscous
or contaminated.
6. Commissioning, operation
Requirements for mounting point
The existence of strong electromagnetic elds in a frequency range of < 100 MHz may result in increased measuring
errors up to 0.5 %. Do not install the instruments in the vicinity of strong electromagnetic sources of interference (e.g.
transmitting devices, radio equipment), or use sheath current lters where applicable.

6.3 Functional check
The output signal must be proportional to the prevailing pressure. If this is not the case, this may indicate a damaged
diaphragm. In this case, see chapter 8 “Faults”.
7. Maintenance and cleaning
7.1 Maintenance
This submersible pressure transmitter is maintenance-free.
Repairs must only be carried out by the manufacturer.
7.2 Cleaning
CAUTION!
■
Prior to cleaning, switch o and disconnect the submersible pressure transmitter from the voltage
supply.
■
Clean the instrument with a moist cloth.
■
Wash or clean the dismounted instrument before returning it, in order to protect persons and the environ-
ment from exposure to residual media.
■
Residual media in dismounted instruments can result in a risk to persons, the environment and
equipment. Take sucient precautionary measures.
■
Do not use any pointed or hard objects for cleaning, as they may damage the diaphragm of the process
connection.
For information on returning the instrument see chapter 9.2 “Return”.
