4.Design and function
4.1Description
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 amplified 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.Transport, packaging and storage
5.1Transport
Check the submersible pressure transmitter for any damage that may have been caused by transport. GB 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, flammable atmospheres
Store the submersible pressure transmitter in its original packaging in a location that fulfils 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 film.
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! |
GB |
Observe the working conditions in accordance with chapter 3 “Specifications”. |
|
CAUTION! |
|
Prior to commissioning, the submersible pressure transmitter must be subjected to a visual inspection. |
|
■■ Leaking fluid 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. |

6.2 Electrical mounting
6.2.1 Connection assembly
■■ Use the submersible pressure transmitter with shielded cable and ground the shield on at least one end of the lead, if the lines are longer than 30 m or leave the building.
■■ When the shield of the cable is being connected, no potential differences should exist between the medium, the vessel and the ground connection of the junction box or the control cabinet.
■■ Make sure that no moisture enters at the cable end.

6.2.3 Setting up a voltage supply
The power supply for the pressure transmitter must be made via an energy-limited electrical circuit in accordance with section 9.3 of UL/EN/IEC 61010-1, or an LPS to UL/EN/IEC 60950-1, or (for North America) class 2 in accordance with
UL1310/UL1585 (NEC or CEC). The power supply must be suitable for operation above 2,000 m should the pressure transmitter be used at this altitude.
■■ Power supply
The power supply depends on the selected output signal.

Voltage output (3-wire): > 100 kΩ
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
7.1Maintenance
This submersible pressure transmitter is maintenance-free. |
GB |
Repairs must only be carried out by the manufacturer. |
|
7.2 Cleaning |
|
CAUTION! |
|
■■ Prior to cleaning, switch off 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 sufficient 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”.
