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 amplied and standardised. 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.

5. Commissioning, 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 proper-
ties of the media. Prior to commissioning, the suitability of the instrument must be ensured (→ for specications, see
chapter 9 “Specications” 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.
■
Sucient space for a safe electrical installation.
■
Permissible ambient and medium temperatures remain within the performance limits.
For performance limits see chapter 9 “Specications”.
5.4 Connecting the instrument
5.4.1 Requirements for voltage supply
→ For power supply see product label
Safety instructions for hazardous locations
Take note of the safety instructions for Ex applications. These safety instructions are attached as “Additional instructions” to each instrument with Ex approval and are part of the operating instructions manual.
14141013.02 08/2018 EN/DE/FR/ES
EN
11WIKA operating instructions submersible pressure sensor, model LF-1
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 oset 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.
▶
For voltage outputs, the load must be specified so that the output current does not exceed 1 mA.

5.4.7 Mounting the instrument
Prior to commissioning, 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 ConguringviaHART 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 parameterise these instruments, operating software with
COMM DTM HART and Device DTM Generic HART (e.g. PACTware
®)
is needed.
The PACTware
®
operating software and the required DTMs are available for download at
www.wika.com.
Connecting submersible pressure sensor to PC (HART
®
)
Any work should only be carried out in a non-hazardous area.
1. Connect HART
®
modem to submersible pressure
sensor.
2. Connect HART
®
modem to PC or notebook.
With repeater power supplies with integrated HART resist-
ances (internal resistance approx. 250 Ω), no additional
external resistance is necessary.
5.6 External display and control units
The DIH50 and DIH52 display and control units are suitable for measured value display and control of instruments with
HART
®
protocol. The respective control unit is looped into the 4 … 20 mA + HART® signal line. For sensors without
HART
®
protocol, the control units are suitable for measured value display.
For further information see the operating instructions of the respective display and control unit.

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.

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 specied.
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.
