2.2 Functional description

The prevailing hydrostatic 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 submersible pressure sensor is amplied and standardized. The

output signal is proportional to the measured hydrostatic pressure.

HART® (option)

The instrument version with HART® can communicate with a controller (master).

Measuring range scaling (turndown)

The start and end of the measuring range can be set within the measuring range.

Do not exceed a turndown of 10:1.

4. Transport, packaging and storage

4.1 Transport

Check the submersible pressure sensor for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
Make sure that the connection contacts are not damaged.

4.2 Packaging and storage

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).

Prior to storage, clean the submersible pressure sensor thoroughly (→ see chapter 7.3.2 “Cleaning”)

Permissible conditions at the place of storage:

■

Storage temperature: -40 °F to -112 °F (-40 °C to 80 °C)

■

Humidity: 45 to 75 % relative humidity (no condensation)

Avoid exposure to the following factors:

■

Direct sunlight or proximity to hot objects

■

Mechanical vibration, mechanical shock (putting it down hard)

■

Soot, vapor, dust and corrosive gases

■

Humid or wet environment

■

Hazardous environments, ammable atmospheres

5. Usage, operation

5.1 Unpacking

When unpacking, do not use any sharp objects (e.g. cutter knives), as this may damage the cable.

Submersible pressure sensors with cable lengths >100 m are wound on cable drums and wrapped

with foil. Unwind the foil manually. The end of the foil is marked with blue tape.

5.2 Suitability for the process conditions

All components of the instrument that are in contact with the process must be suitable for the process

conditions that may exist. Included in this are particularly the process pressure, process temperature

and also the chemical properties of the media. Prior to usage, the suitability of the instrument must be

ensured (For specications, see chapter 9 “Specications” and the product label).

5.3 Requirements for mounting point

The mounting point must meet the following conditions:

■

The diaphragm is protected from contact with abrasive media and against any impacts.

■

The cable contains a capillary for the pressure compensation. Therefore, the cable must be

connected in a dry space or a suitable terminal enclosure.

■

Su󰀩cient space for a safe electrical installation.

■

Permissible ambient and medium temperatures remain within the performance limits.

For performance limits see chapter 9 “Specications”.

5.4.2 Requirements for electrical connection

Cable diameter matches the cable bushing of the terminal enclosure.
Cable gland and seals are correctly seated.
No humidity can ingress at the cable end.

5.4.3 Requirement for shielding and grounding

The submersible pressure sensor must be shielded and grounded in accordance with the grounding
concept of the plant.

5.4.4 Fitting the measuring point tag

Before the submersible pressure sensor is wired, the measuring point tag must be attached to the
cable. The measuring point tag acts to identify the submersed instrument and contains a copy of the
product label.

1.

Remove the packaging at the cable end

2.

Thread the measuring point tag onto the cable.
The rubber stops at the measuring point tag protect the cable and must be undamaged and correct
mounted. Position the measuring point tag so that, in the mounted state, it is easily reachable and
protected against harsh environmental conditions.

5.4.5 Shortening the cable

The cable can be shortened as required. With submersible pressure sensors with voltage output, a

shortening of the cable results in an o󰀨set error: ≤ 0.014 % / m of shortened cable.

After the shortening, provide the wire ends with end splices and position the lter element on the vent

tube.

5.4.6 Connecting the instrument to the electric system

▶

Connect the cables to the terminals.

5.4.7 Mounting the instrument

Prior to usage, the submersible pressure sensor must be subjected to a visual inspection.

■

Leaking uid is indicative of damage.

■

Only use the submersible pressure sensor if it is in perfect condition with respect to safety.

The protection cap protects the internal diaphragm from damage during transport and during the
lowering of the probe. With viscous or contaminated media, the protection cap can be removed in order
to ensure trouble-free operation.

When laying the cable, a minimum bending radius of 120 mm must be ensured.

5.5 Conguring via HART® interface

The HART® modem with RS232, USB or Bluetooth interface (→ see Accessories) enables the

connection of communicating instruments to the respective interface of a PC. To parameterize these

instruments, operating software with COMM DTM HART and Device DTM Generic HART (e.g.
PACTware®) is needed.

The operating software and the required DTMs are available for download at
www.noshok.com.

Connecting submersible pressure sensor to PC (HART®)

Any work should only be carried out in a non-hazard­ous area.

6. Faults

6. Faults

CAUTION!
Physical injuries and damage to property and the environment

If faults cannot be eliminated by means of the listed measures, the submersible pressure

sensor must be taken out of operation immediately.

▶

Ensure that pressure or signal is no longer present and protect against accidental
commissioning.

▶

Contact the manufacturer.

▶

If a return is needed, please follow the instructions given in chapter 8.2 “Return”.

WARNING!
Physical injuries and damage to property and the environment caused by
hazardous media

Upon contact with hazardous media (e.g. oxygen, acetylene, ammable or toxic

substances), harmful media (e.g. corrosive, toxic, carcinogenic, radioactive), and also
with refrigeration plants and compressors, there is a danger of physical injuries and
damage to property and the environment.

▶

Should a failure occur, aggressive media with extremely high temperature and under

high pressure or vacuum may be present at the instrument.

▶

For these media, in addition to all standard regulations, the appropriate existing codes
or regulations must also be followed.

▶

Wear the required protective equipment.

For contact details see chapter 1 “General information” or the back page of the operating

instructions

7. Maintenance and cleaning

7. Maintenance and cleaning

7.1 Maintenance

When used in strongly contaminated and adhesive media, the pressure port of the submersible
pressure sensor has to be cleaned regularly. The cleaning interval is dependent upon the respective
application. The checking and cleaning of the pressure port should thus be added to the maintenance

plan. Since the cleaning intervals are dependent on the operating conditions, no universal time periods
can be specied.

Repairs must only be carried out by the manufacturer.

7.2 Cleaning

WARNING!
Physical injuries and damage to property and the environment through residual
media

Residual media at the dismounted instrument can result in a risk to persons, the
environment and equipment.

▶

With hazardous substances, observe the material safety data sheet for the
corresponding medium.

▶

Wear the requisite protective equipment.

CAUTION!
Unsuitable cleaning agents

Cleaning with unsuitable cleaning agents may damage the instrument and the product
label.

▶

Do not use any aggressive cleaning agents.

▶

Do not use any hard or pointed objects.

▶

Do not use any abrasive cloths or sponges.

damage to property and the environment.

▶

Should a failure occur, aggressive media with extremely high temperature and under

high pressure or vacuum may be present at the instrument.

▶

Wear the required protective equipment.

Dismounting the instrument

8.2 Return

Strictly observe the following when shipping the instrument:

All instruments delivered to NOSHOK must be free from any kind of hazardous substances (acids,

bases, solutions, etc.) and must therefore be cleaned before being returned.

WARNING!
Physical injuries and damage to property and the environment through residual
media

Residual media in the dismounted instrument can result in a risk to persons, the
environment and equipment.
