3 Product description
Fig. 2: Electronic level dierence measurement through Master/Slave combination
Application area
The VEGABAR 87 is a pressure transmitter for pressure and level
measurements of liquids with higher temperatures in the chemical,
food processing and pharmaceutical industry.
Measured products
Measured products are liquids.
Depending on the instrument version and the measurement setup,
the measured products can be also viscous.
Measuring system
The process pressure acts on the sensor element via the stainless
steel diaphragm and an internal transmission liquid. The process
pressure causes a resistance change which is converted into a corresponding output signal and outputted as measured value.
The METEC® measuring cell is the measuring unit. It consists of
the ceramic-capacitive CERTEC® measuring cell and a special,
temperature-compensated isolating system.

Pressure types
Measuring system
The measuring cell design depends on the selected pressure type.
Relative pressure: the measuring cell is open to atmosphere. The
ambient pressure is detected in the measuring cell and compensated.
It thus has no inuence on the measured value.
Absolute pressure: the measuring cell is evacuated and encapsulated. The ambient pressure is not compensated and does hence
inuence the measured value.
Relative pressure, climate-compensated: the measuring cell is
evacuated and encapsulated. The ambient pressure is detected
through a reference sensor in the electronics and compensated. It
thus has no inuence on the measured value.
The process pressure acts on the sensor element via the stainless
steel diaphragm and an internal transmission liquid. The process
pressure causes a resistance change which is converted into a corresponding output signal and outputted as measured value.
The METEC® measuring cell is the measuring unit. It consists of
the ceramic-capacitive CERTEC® measuring cell and a special,
temperature-compensated isolating system.

4.2 Ventilation and pressure compensation
Ventilation and pressure compensation are carried out with VEGABAR 87 via a lter element. It is air permeable and moisture-
blocking.
Caution:
The lter element causes a time-delayed pressure compensation.
When quickly opening/closing the housing cover, the measured value
can change for approx. 5 s by up to 15 mbar.
For eective ventilation, the lter element must always be free of
buildup.
Caution:
Do not use a high-pressure cleaner. The lter element could be damaged, which would allow moisture into the housing.
The following paragraphs describe how the lter element is arranged
in the dierent instrument versions.

VEGABAR 87 • Slave sensor for electronic dierential pressure
In this menu item, you determine the units for the "Min. adjustment/
zero" and "Max. adjustment/span" as well as the static pressure.
If the level should be adjusted in a height unit, the density of the medium must also be entered later during the adjustment.
In addition, the unit for the measuring cell and electronics temperature
is determined in the menu item "Peak values".
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Particularly with chemical seal systems, the installation position of
the instrument can shift the measured value (oset). The position
correction compensates this oset. Hence the actual measured value
is accepted automatically. With relative pressure measuring cells also
a manual oset can be carried out. With a master/slave combination,
the position correction is carried out for both sensors.
If the actual measured value should be taken over as correction value
during automatic position correction, this value must not be inuenced by product coverage or static pressure.
With the manual position correction, the oset value can be determined by the user. Select for this purpose the function "Edit" and
enter the requested value.
29
Page 30
6 Set up with the display and adjustment module
Save your settings with [OK] and move with [ESC] and [->] to the
next menu item.
After the position correction is carried out, the actual measured value
is corrected to 0. The corrective value appears with an inverse sign as
oset value in the display.
The position correction can be repeated as often as necessary. How-
ever, if the sum of the corrective values exceeds 20 % of the nominal
measuring range, then no position correction is possible.
Parameterization example
VEGABAR 87 always measures pressure independently of the process variable selected in the menu item "Application". To output the
selected process variable correctly, an allocation to 0 % and 100 % of
the output signal must be carried out (adjustment).
With the application "Interface" the hydrostatic pressure at min. and
max. height of the interface is entered for adjustment. See the follow-
ing example:
100%
2
0,8
1,0
Fig. 20: Parameter adjustment example "Min./max. adjustment, interface
measurement"

If these values are not known, an adjustment with interface layers of
for example 10 % and 90 % is also possible. By means of these settings, the layer of the actual interface is then calculated.
The real product level during the adjustment is not important,
because the adjustment is always carried out without changing the
product level. These settings can be made ahead of time without the
instrument having to be installed.
