3.2Principle of operation
VEGABAR 52 is a pressure transmitter for use in the paper, food processing and pharmaceutical industries as well as in water/sewage water plants. Depending on the version, it is used for level, gauge, absolute pressure or vacuum measurement. Measured products are gases, vapours and liquids, also those containing abrasive substances.
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.

General instructions |
Suitability for the process |
Make sure that all parts of the instrument coming in direct contact |
||
conditions |
with the process, especially the sensor element, process seal and |
||
|
|
process fitting, are suitable for the existing process conditions, such |
|
|
|
as 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 |
|
|
|
nameplate. |
|
Installation position |
Select an installation position you can easily reach for mounting and |
||
|
|
connecting as well as later retrofitting of a display and adjustment |
|
|
|
module. The housing can be rotated by 330° without the use of any |
|
|
|
tools.You can also install the display and adjustment module in four |
|
|
|
different positions (each displaced by 90°). |
|
Moisture |
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
Ventilation and pressure The ventilation of the electronics housing as well as the atmospheric compensation pressure compensation for the measuring cell are realised via a filter element in the area of the cable gland.

Caution:
Due to the filter effect, the pressure compensation is time delayed.
When opening/closing the housing cover quickly, the measured value can change for a period of approx. 5 s by up to 15 mbar.
Information:
Make sure that the filter element is always free of buildup during operation. A high-pressure cleaner may not be used for cleaning.
With instrument versions in protection IP 66/IP 68, 1 bar, the ventilation is realised via the capillaries in the permanently connected cable.
The filter element is replaced by a blind plug.
Temperature limits |
Higher process temperatures often mean also higher ambient |
|
temperatures. Make sure that the upper temperature limits stated in |
|
chapter "Technical data" for the environment of the electronics hous- |
|
ing and connection cable are not exceeded. |

screen. If electromagnetic interference is expected which is above the |
||
|
|
|
|
|
|
test values of EN 61326 for industrial areas, screened cable should |
||
|
|
|
|
|
|
be used. |
||
|
|
|
|
|
|
Use cable with round cross-section.A cable outer diameter of |
||
|
|
|
|
|
|
5 … 9 mm (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. |
||
|
|
|
|
|
|
We generally recommend the use of screened cable for HART multi- |
||
|
|
|
|
|
|
drop mode. |

Cable screening and grounding
housing.This would influence the stability of the connection and the tightness of the housing.
If screened cable is necessary, connect the cable screen on both ends to ground potential. In the sensor, the screen must be connected directly to the internal ground terminal. The ground terminal on the outside of the housing must be connected to the potential equalisation (low impedance).
If potential equalisation currents are expected, the connection on the processing side must be made via a ceramic capacitor (e. g. 1 nF, 1500 V). The low-frequency potential equalisation currents are thus suppressed, but the protective effect against high frequency interference signals remains.
Warning:
Considerable potential differences exist inside galvanic plants as well as vessels with cathodic corrosion protection. Very large equalisation currents can flow through the cable screen when the screen
is grounded on both ends. To avoid this, the cable screen must be connected to ground potential only on one end (inside the switching cabinet) in such applications. The cable screen must not be connected to the internal ground terminal in the sensor and the outer ground terminal on the housing not to potential equalisation!
Information:
The metallic parts of the instrument (transmitter, process fitting, etc.) are conductively connected with the inner and outer ground terminal on the housing. This connection exists either as a direct metallic contact or via the shielding of the special connection cable on instruments with external electronics.You can find specifications on the potential connections within the instrument in chapter "Technical data".
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.

5.2Connection procedure
Proceed as follows:
1.Unscrew the housing cover
2.If a display and adjustment module is installed, remove it by turning it to the left.
3.Loosen compression nut of the cable entry
4.Remove approx. 10 cm of the cable mantle, strip approx. 1 cm insulation from the individual wires
5.Insert the cable into the sensor through the cable entry
6.Lift the opening levers of the terminals with a screwdriver (see following illustration)
7.Insert the wire ends into the open terminals according to the wiring plan

8.Press down the opening levers of the terminals, you will hear the terminal spring closing
9.Check the hold of the wires in the terminals by lightly pulling on them
10.Connect the screen to the internal ground terminal, connect the outer ground terminal to potential equalisation
11.Tighten the compression nut of the cable entry. The seal ring must completely encircle the cable
12.Screw the housing cover back on
The electrical connection is hence finished.
