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

beyond that described in the operating instructions manual may be

carried out only by personnel authorised by the manufacturer.Arbitrary

conversions or modiﬁcations are explicitly forbidden.

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

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
