Ametallic measuring cell is used as sensor element.The process
pressures are transmitted via the separating diaphragms and filling oils
to a resistance measuring bridge (semi-conductor technology).
The difference of the existing pressures generates a change of the
bridge voltage.This change is measured,further processed and
converted into a corresponding output signal.

For connection to the processe,the marking "+"and "-"on the process
component in chapter "Mounting and connection instructions"must
hence be noted.The pressure effective on "+"goes positive,the
effective pressure on "-"goes negative into the calculation of the
pressure difference.

Power is supplied via the H1Fieldbus.Atwo-wire cable according to
Fieldbus specification serves as carrier of both power and digital data
for multiple sensors.This cable can be operated in two versions:
lvia an H1interface card in the control system and additional power
supply

The DD (Device Descriptions)and CFF (capability files)necessary for
planning and configuration of your FF (Foundation Fieldbus)commu-
nication network are available in the download area of the VEGA
homepage www.vega.com under "Services -Downloads -Software -
Foundation Fieldbus".The appropriate certificates are also available
there.A CD with the appropriate files and certificates can be ordered
via e-mail under [e-mail] or by phone from one of the VEGA
agencies under the order number "DRIVER.S".
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".
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.
3.3Operation
The instrument can be adjusted with the following 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
la configuration tool
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.

4.1General instructions to use the instrument
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.
Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give the 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.
The ventilation for the electronics housing is realised via a filter
element in the vicinity of the cable glands.

36130-EN-110510

DP flow elements are calculated for certain pipeline and operating
data.Therefore,check the pipeline data before installation at the
measuring point and compare the measurement loop number.
Detailed instructions for mounting the DP flow element are stated in
DIN EN ISO 5167 as well as in the instrument documentation from the
respective manufacturer.
You will find general recommendations for the installation of effective
pressure lines in DIN 19210 "Effective pressure lines for flow systems"
or the corresponding national or international standards.When
installing effective pressure lines outdoors,consider applying suitable
anti-freeze protection,e.g.tube heating.Install effective pressure lines
with a monotonic downward slope of at least 10 %.
In case of strong vibrations at the application position,the instrument
version with external electronics should be used.
Higher process temperatures often mean also higher ambient
temperatures for electronics and connection cable.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.
4.2Instructions for oxygen and ultra-pure gas
applications
Oxygen and other gases can be explosive when brought into contact
with oils,grease and plastics,so the following measures must also be
taken:
lAll components of the plant,such as e.g.measuring instruments
must be cleaned according to the requirements of BAM
(DIN 19247)
lDepending on the seal material,certain temperatures and
pressures must not be exceeded in oxygen applications,see
chapter "Technical data"
Danger:
Instruments for oxygen applications must be unpacked just before
mounting.After removing the protective cover of the process fitting,the
label "O₂"will be visible on the process fitting.Penetration of oil,
grease and dirt should be avoided.Danger of explosion!
We also offer oil and grease free instruments for special applications
such as e.g.ultra-pure gas.There are no special restrictions with
respect to the process conditions.

The use of the valve block with inlet and outlet valves allows simple
installation and setup of the differential pressure transmitter.The valve
block separates the differential pressure transmitter from the process
side and enables simple maintenance and checking of the measure-
ment loop.The integrated equalization valve ensures the same
pressure conditions on the plus and minus side during setup.The five-
fold valve block contains also two valves for checking/ventilating the
differential pressure transmitter after it is installed.
The valve block is used for direct connection to the differential
pressure transmitter.The following figure shows the connection of a 5-
fold valve block.
