The serial number allows you to access the delivery data of the
instrument via www.vega.com,"VEGA Tools"and "serial number
search".In addition to the type label outside,you can also find the
serial number on the inside of the instrument.
Instruments in the version "Oil and grease-free for oxygen applica-
tions"are equipped with a supplementary label.The supplementary
label contains instructions on oil and grease-free parts of the
instrument.
3.2Principle of operation
The VEGABAR 51 is a pressure transmitter with isolating diaphragm
for pressure measurement of highly corrosive and hot liquids.
The sensor element for measuring ranges up to 60 bar is the
CERTEC
®
measuring cell with rugged ceramic diaphragm.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 system.This change is converted into a
corresponding output signal.1)
The sensor element for measuring ranges from 100 bar is a wire strain
gauge (DMS)on the rear of the process diaphragm.There,the
process pressure causes a resistance change,which is converted into
an appropriate output signal.
Power supply via the Profibus DP/PA segment coupler or VEGALOG
571 EP cards.Atwo-wire cable according to Profibus specification
serves as carrier of both power and digital data transmission for
multiple sensors.The instrument profile of VEGABAR 51 corresponds
to profile specification version 3.0.
The backlight of the indicating and adjustment module is powered by
the sensor.Prerequisite is a certain level of operating voltage.
The data for power supply are specified in chapter "Technical data".
1)The isolating system protects the sensor against corrosive products and
high temperatures.By selecting suitable diaphragm materials and isolating
liquids,systems with a temperature resistance up to 400 °C(752 °F)can be
achieved.

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.
The GSD (instrument master files)and bitmap files necessary for
planning your Profibus-DP-(PA)communication network are available
from the download section on the VEGA homepage www.vega.com
under "Services -Downloads -Software -Profibus".There you can
also find the appropriate certificates.In a PDM environment,an EDD
(Electronic Device Description)is also required to enable the full range
of sensor functions (also available as a download).A CD with the
appropriate files can be ordered via e-mail under [e-mail] or
by phone from one of the VEGA agencies under the order number
"DRIVER.S".
3.3Operation
VEGABAR 51 can be adjusted with different adjustment media:
lwith indicating and adjustment module
lwith the suitable VEGA DTM in conjunction with an adjustment
software according to the FDT/DTM standard,e.g.PACTware and
PC
lwith the adjustment program PDM
3.4Packaging,transport and storage
Your instrument was protected by packaging during transport.Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of environment-
friendly,recyclable cardboard.For special versions,PE foam or PE foil
is also used.Dispose of the packaging material via specialised
recycling companies.
Caution:
Instruments for oxygen applications are sealed in PE foil and provided
with a label "Oxygen!Use no Oil".Remove this foil just before
mounting the instrument!See instruction under "Mounting".
Transport must be carried out under 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
concealed defects must be appropriately dealt with.
