3.2 Principle of operation
The VEGABAR 86 is a submersible pressure transmitter for level
measurementinwells,basinsandopenvessels.Itsgreatexibility
throughdierentcableandtubeversionsallowstheinstrumenttobe
usedinmanydierentapplications.
Measured products are liquids.
Depending on the instrument version and measurement setup, meas-
ured products can also be viscous or contain abrasive substances.
The VEGABAR 86 is suitable for the measurement of the following
process variables:
• Level

VEGABAR 86 • HART and accumulator pack
45040-EN-210430
Fig. 2: Level measurement with VEGABAR 86
The sensor element is the CERTEC®measuring cell with robust
ceramicdiaphragm.Theprocesspressuredeectstheceramic
diaphragm and causes a capacitance change in the measuring cell.
This capacitance change is converted into an electrical signal and
outputted as measured value via the output signal.
The measuring cell is available in two sizes:
• CERTEC®(ø28mm)withsensor32mm
• Mini-CERTEC®(ø17.5mm)withsensor22mm
A temperature sensor in the ceramic diaphragm of the CERTEC®or
on the ceramic base of the Mini-CERTEC®measuring cell detects the
actual process temperature. The temperature value is output via:
• The display and adjustment module
• The current output or the additional current output
• The digital signal output
Even extreme jumps in process temperature are immediately de-
tected by the CERTEC®measuring cell. The values in the ceramic
diaphragm are compared with those on the ceramic base body. Within
a few measuring cycles, the intelligent sensor electronics compen-
sates for otherwise unavoidable measurement deviations caused by
temperature shocks in the range. Depending on the adjusted damp-
ing, these cause only slight and brief changes in the output signal. 1)
The measuring cell design depends on the selected pressure type.
Relative pressure: the measuring cell is open to the atmosphere.
The ambient pressure is detected in the measuring cell and compen-
sated.Itthushasnoinuenceonthemeasuredvalue.

temperatures below 95 °C it is automatically reactivated.

Absolute pressure: the measuring cell contains vacuum and is
encapsulated. The ambient pressure is not compensated and does
henceinuencethemeasuredvalue.
Relative pressure, climate-compensated: the measuring cell is
evacuated and encapsulated. The ambient pressure is detected
through a reference sensor in the electronics and compensated. It
thushasnoinuenceonthemeasuredvalue.

ing cell in the sensor as well as the sealing concept.

3.3 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging consists of environment-friendly, recyclable card-
board. For special versions, PE foam or PE foil is also used. Dispose
of the packaging material via specialised recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media

4.1 General instructions
Note:
For safety reasons, the instrument must only be operated within the
permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter "Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Processtting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasionandmechanicalinuences
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter "Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidityisexpected(e.g.throughcleaningprocesses)andoncooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Deviceswiththreadedttingarescrewedintotheprocessttingwith
a suitable wrench via the hexagon.
See chapter "Dimensions" for wrench size.
Warning:
The housing or the electrical connection may not be used for screw-
ing in! Depending on the device version, tightening can cause dam-
age, e. g. to the rotation mechanism of the housing.
Avoid damages on the device by lateral forces, for example by vibra-
tions.Itisthusrecommendedtoxthedeviceswithprocesstting

thread G½ of plastic at the installation site via a suitable measuring
instrument holder.
If there is strong vibration at the mounting location, the instrument
version with external housing should be used. See chapter "External
housing".
Thepermissibleprocesspressurerangeisspeciedonthetypelabel
with"MWP"(MaximumWorkingPressure),seechapter"Congura-
tion". This applies even if a measuring cell with a measuring range
(order-related)higherthanthepermissiblepressurerangeofthe
processttingisinstalled.
Inaddition,atemperaturederatingoftheprocesstting,e.g.with
anges,canlimitthepermissibleprocesspressurerangeaccording
to the respective standard.
The permissible process pressure range is stated on the type label.
The instrument should only be operated with these pressures if the
mountingaccessoryusedalsofullsthesevalues.Thisshouldbeen-
suredbysuitableanges,weldedsockets,tensionringswithClamp
connections, sealings, etc.
Higher process temperatures often mean also higher ambient
temperatures. Make sure that the upper temperature limits stated in
chapter "Technical data" for the environment of the electronics hous-
ing and connection cable are not exceeded.

2 Transport and mounting protection
Remove this protection after mounting and before setting up the
instrument.
In case of slightly contaminated measured media, the transport and
mounting protection can remain on the instrument as an impact pro-
tection during operation.
4.2 Ventilation and pressure compensation
Thelterelementintheelectronicshousinghasthefollowingfunc-
tions:
• Ventilation of the electronics housing
• Atmospheric pressure compensation (with relative pressure meas-
uringranges)
Caution:
Thelterelementcausesatime-delayedpressurecompensation.
Whenquicklyopening/closingthehousingcover,themeasuredvalue
can change for approx. 5 s by up to 15 mbar.
Foraneectiveventilation,thelterelementmustbealwaysfreefrom
buildup. In case of horizontal mounting, turn the housing so that the
lterelementpointsdownwardaftertheinstrumentisinstalled.This
provides better protection against buildup.
Caution:
Donotuseahigh-pressurecleaner.Thelterelementcouldbedam-
aged, which would allow moisture into the housing.
Thefollowingparagraphsdescribehowthelterelementisarranged
inthedierentinstrumentversions.

After switching on, the instrument carries out a self-check for approxi-
mately 30 s:
• Internal check of the electronics
• Indication of a status message, e.g. "F 105 Determine measured
value" on the display
Then the actual measured value is output to the signal cable. The
