carried out only by trained specialist personnel authorised by the plant
operator.
During work on and with the device the required personal protective
equipment must always be worn.
2.2Appropriate use
VEGABAR 12 is a pressure transmitter for the bubble-through method
with neutral gases.
You can find detailed information on the application range in chapter
"Product description".
Operational reliability is ensured only if the instrument is properly used
according to the specifications in the operating instructions manual as
well as possible supplementary instructions.
For safety and warranty reasons,any invasive work on the device

2.5Safety label on the instrument
The safety approval markings and safety tips on the device must be
observed.
2.6CE conformity
This device fulfills the legal requirements of the applicable EC
guidelines.By attaching the CE mark,VEGA provides a confirmation
of successful testing.You can find the CE conformity declaration in the
download area of www.vega.com.
2.7Measuring range -permissible process pres-
sure
Due to the application,a measuring cell with higher measuring range
than the permissible pressure range of the process pressure can be
integrated.The permissible process pressure is stated with "process
pressure"on the type label,see chapter 3.1"Configuration".For safety
reasons,this range must not be exceeded.
2.8Environmental instructions
Protection of the environment is one of our most important duties.That
is why we have introduced an environment management system with
the goal of continuously improving company environmental protection.
The environment management system is certified according to DIN
EN ISO 14001.
Please help us fulfil this obligation by observing the environmental
instructions in this manual:

3.2Principle of operation
VEGABAR 12 is a pressure transmitter for gauge pressure measure-
ment of neutral gases.
The sensor element is the CERTEC
®
measuring cell with rugged
ceramic diaphragm.The process pressure causes a capacitance
change in the measuring cell via the ceramic diaphragm.This change
is converted into an appropriate output signal and outputted as
measured value.
Two-wire electronics 4…20 mAfor power supply and measured
value transmission over the same cable.
3.3Operation
The optional operation of the instrument is carried out via a PC with
interface adapter and VEGA adjustment software.
3.4Packaging,transport and storage
The device 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.
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.
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:
lNot in the open
lDry and dust free
lNot exposed to corrosive media
lProtected against solar radiation
lAvoiding mechanical shock and vibration
