operator.
During work on and with the device the required personal protective
equipment must always be worn.
orised personnel
2.2 Appropriate use
VEGABAR 17 is a pressure transmitter for measurement of gauge
pressure, absolute pressure and vacuum.
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

on the instrument
2.6 CE conformity
The device fulfills the legal requirements of the applicable EC
guidelines. By affixing the CE marking, we confirm successful testing
of the product.
You can find the conformity ce rtificate in the download section of our
homepage.
2.7 Measuring range - permissible process pres-
sure
Due to the application, a measuring cell with a measuring range higher
than the permissible pressure range of the process fitting may have
been 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.
2.8 Safety instructions for Ex areas
Please note the Ex-specific safety information for installation and
operation in Ex areas. These safety instructions are part of the
operating instructions manual and come with the Ex-approved
instruments.
2.9 Environmental 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:

3.2 Principle of
operation
VEGABAR 17 is a pressure transmitter for measurement of gauge
pressure, absolute pressure or vacuum. Measured products are
gases, vapours and liquids. The front flush versions are also suitable
for use in viscous or contaminated products.
The process pressure acts on the sensor element via the stainless
steel diaphragm. The process pressure causes a resistance change
which is converted into a corresponding output signal and outputted as
measured value.
1)
4 … 20 mA two-wire electronics for voltage supply and measured
value transmission on the same cable.
3.3 Operation
The VEGABAR 17 has no adjustment options.
However, there are two built-in potentiometers for recalibration of zero
and span.
3.4 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
according to DIN EN 24180.
The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil
is also used. Dispose of the packaging material via specialised
recycling companies.
Transport
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
Transport inspection
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.
Storage
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:

4.1 General ins
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" and on the
type label.
To protect the diaphragm, the process fitting is covered by a protective
cap.
Remove the protective cap just before installation so that the
diaphragm will not get damaged. It is recommended to keep the cap
and use it again later for storage or transport.

For mounting VEGABAR 17, a welded socket is required. You can find
these components in the supplementary instructions manual "Welded
socket and seals".
Use the seal fitting to the instrument, or in case of NPT connections, a
high-resistance sealing material.
Screw VEGABAR 17 into the welded socket with a wrench applied to
the hexagon of the process fitting. For the proper torque see chapter
"Technical data", for spanner size see chapter "Dimensions".
