Sensor element is the CERTEC
®
measuring cell with robust,
dependent on the process fitting also front-flush,abrasion-resistant
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.
The CERTEC
®
measuring cell is also equipped with a temperature
sensor.The temperature value can be displayed via the indicating and
adjustment module as well as processed via the signal output (with
digital versions).
As a standard feature,the CERTEC
®
measuring cell is equipped with
a lateral,recessed seal.

4.1General instructions
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.
Select an installation position you can easily reach for mounting and
connecting as well as later retrofitting of an indicating and adjustment
module.The housing can be rotated by 330°without the use of any
tools.You can also install the indicating and adjustment module in four
different positions (each displaced by 90°).
Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give your 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.
Fig.3:Measures against moisture penetration
4.2Mounting steps
For mounting VEGABAR 54,a welded socket is required.You can find
these components in the supplementary instructions manual "Welded

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
lIf voltage surges are expected,overvoltage arresters should be
installed according to Profibus specifications
Tip:
We recommend VEGA overvoltage arrester B63-32.
In hazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
Power is supplied via a Profibus DP/PA segment coupler or a
VEGALOG 571 EP input card.The power supply range can differ
depending on the instrument version.
The data for power supply are specified in chapter "Technical data".
Connection is made with screened cable according to the Profibus
specification.Power supply and digital bus signal are carried over the
same two-wire connection cable.
Use cable with round cross-section.Acable outer diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable gland.If you are
using cable with a different diameter or cross-section,exchange the
seal or use a suitable cable gland.
Please make sure that your installation is carried out according to the
Profibus specification.In particular,make sure that the termination of
the bus is done with appropriate terminating resistors.
On the instrument with cable entry ½NPT and plastic housing there is
a metallic ½" threaded insert moulded into the plastic housing.
Caution:
No grease should be used when screwing the NPT cable gland or
steel tube into the threaded insert.Standard grease can contain
additives that corrode the connection between threaded insert and
housing.This would influence the stability of the connection and the
tightness of the housing.
With systems with potential equalisation,connect the cable screen
directly to ground potential at the power supply unit,in the connection
box and at the sensor.The screen in the sensor must be connected
directly to the internal ground terminal.The ground terminal outside on
the housing must be connected to the potential equalisation (low
impedance).

5Connecting to power supply
36729-EN-120324

In systems without potential equalisation,connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor,the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen.The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g.1nF,1500 V). Low-
frequency potential equalisation currents are thus suppressed,but the
protective effect against high frequency interference signals remains.
The total capacitance of the cable and of all capacitors must not exceed
10 nFin Ex applications.
Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equalisation
currents flow over the cable screen.In case of grounding on both sides
this can be achieved by the use of a capacitor or a separate potential
equalisation.
