3.2Principle of operation
VEGABAR 55 is a pressure transmitter for use in the chemical,food
processing and pharmaceutical industries.Depending on the version,
it is used for level,gauge,absolute pressure or vacuum measurement.
Measured products are gases,vapours and liquids,also those with
higher temperatures.
The METEC
®
measuring cell is the measuring unit.It consists of the
ceramic-capacitive CERTEC
®
measuring cell and a special,temper-
ature-compensating isolating system.
The hydrostatic pressure of the product or the process pressure
causes a capacitance change in the measuring cell via the metal
process diaphragm and the isolating liquid.This change is converted
into a corresponding output signal.
Two-wire electronics 4…20 mAfor power supply and measured
value transmission over the same cable.
The supply voltage range can differ depending on the instrument
version.The exact range is stated in chapter "Technical data".
The background lighting of the indicating and adjustment module is
powered by the sensor.Acertain level of operating voltage is required
for this.You can find the exact voltage specifications in chapter
"Technical data".
The optional heating requires its own operating voltage.You can find
details in the supplementary instructions manual "Heating for indicat-
ing and adjustment module".
This function is generally not available for approved instruments.

4Mounting
4.1General instructions
Make sure that all parts of the instrument exposed to the process,in
particular the sensor element,process seal and process fitting,are
suitable for the existing process conditions.These include above all
the process pressure,process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data"or on the
type label.
Caution:
After removal of the diaphragm protective cover,the diaphragm must
not be pressed.
Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module.The housing can be rotated by 330°without the use of any
tools.You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry.Rain and condensation water can thus drain off.This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g.through cleaning processes)or
on cooled or heated vessels.

Caution:
Due to the filter effect,the pressure compensation is time delayed.
When opening/closing the housing cover quickly,the measured value
can change for a period of approx.5s by up to 15 mbar.
Information:
Make sure that the filter element is always free of buildup during
operation.Ahigh-pressure cleaner must not be used for cleaning.
With instrument versions in protection IP 66/IP 68,1bar,the ventilation
is realised via the capillaries in the permanently connected cable.The
filter element is replaced by a blind stopper.
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 housing
and connection cable are not exceeded.

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltage surges are expected,overvoltage arresters should
be installed
Tip:
We recommend using VEGA overvoltage arresters B63-48 and
ÜSB 62-36G.X.
In hazardous areas you should take note of the appropriate regulations,
conformity and type approval certificates of the sensors and power
supply units.
Power supply and current signal are carried on the same two-wire
cable.The voltage supply range can differ depending on the
instrument version.
The data for power supply are specified in chapter "Technical data".
Provide a reliable separation between the supply circuit and the mains
circuits according to DIN VDE 0106 part 101.The VEGA power supply
units VEGATRENN 149A Ex,VEGASTAB 690 as well as all
VEGAMETs and VEGASCANs meet this requirement.
Information:
The signal conditioning instruments VEGAMET 624 and 625 as well as
VEGASCAN 693 have a digital sensor recognition.When connecting
VEGABAR 55,a software version from 1.92 is required with the signal
conditioning instrument.For software update move under "www.vega.
com/downloads"to "Software".
Keep in mind the following additional influences on the operating
voltage:
lOutput voltage of the power supply unit can be lower under
nominal load (with a sensor current of 20.5mAor 22 mAin case of
fault message)
lInfluence of additional instruments in the circuit (see load values in
chapter "Technical data")
The instrument is connected with standard two-wire cable without
screen.If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas,screened cable should be
used.
Safety instructions
Power supply
Connection cable
VEGABAR 55 •4…20 mA15
5Connecting to power supply
36733-EN-091008

Use cable with round cross-section.Acable outer diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable gland.If you are
using cable with a different diameter or cross-section,exchange the
seal or use a suitable cable gland.
We generally recommend the use of screened cable for HART
multidrop mode.
On the instrument with cable entry ½NPT and plastic housing there is
a metallic ½" threaded insert moulded into the plastic housing.
Caution:
No grease should be used when screwing the NPT cable gland or
steel tube into the threaded insert.Standard grease can contain
additives that corrode the connection between threaded insert and
housing.This would influence the stability of the connection and the
tightness of the housing.
If screened cable is necessary,connect the cable screen on both ends
to ground potential.In the sensor,the screen must be connected
directly to the internal ground terminal.The ground terminal on the
outside of the housing must be connected to the potential equalisation
(low impedance).
If potential equalisation currents are expected,the connection on the
processing side must be made via a ceramic capacitor (e.g.1nF,
1500 V). The low frequency potential equalisation currents are thus
suppressed,but the protective effect against high frequency interfer-
ence signals remains.
Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equalisation
currents flow over the cable screen.In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2If an indicating and adjustment module is installed,remove it by
turning it slightly to the left.
