VEGABAR 87 • Slave sensor for electronic differential pressure
45053-EN-131011
The following applications are available:
•
Level
•
Flow
•
Differential pressure
•
Density
•
Interface
Note:
It is absolutely necessary to activate the slave sensor in advance to
have the applications displayed in the electronic differential pressure
measurement menus.
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.
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 me-
dium 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 (offset). The position
correction compensates this offset. Hence the actual measured value
is accepted automatically. With relative pressure measuring cells also
a manual offset 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 influ-
enced by product coverage or static pressure.
With the manual position correction, the offset value can be deter-
mined by the user. Select for this purpose the function "Edit" and
enter the requested value.
