VEGAPULS 42 and 44 – 4 … 20 mA 65
Setup
With the menu item " Operating range “, you
can define the operating range of the sensor
deviating from the " Min/Max adjustment “. By
default, the operating range corresponds
otherwise to the min./max. adjustment, i.e. the
span.
Generally, it is better to choose the operating
range approx. 5 % bigger than the adjusted
measuring range (span) determined by the
min./max. adjustment.
In the example:
- Min. adjustment to 1.270 m,
- Max. adjustment to 5.85 m.
In the example you would have set the oper-
ating range from 1 m to 6 m.
• Save the adjustments and quit the menu
window " Limitation of the operating range“ .
Meas. environment/Meas. conditions
• Click to " Measuring conditions “.
• In the menu window " Measuring condi-
tions “ you click on the options correspond-
ing to your application.
After a few seconds during which the adjust-
ments are permanently saved in the sensor,
you are again in the window " Meas. environ-
ment “.
Meas. conditions/Pulse velocity
In the menu item " Pulse velocity “ adjustments
are only necessary when measuring in a
surge or bypass tube (standpipe). When
measuring in a standpipe, a shift of the run-
ning time of the radar signal (dependent on
the inner diameter of the standpipe) occurs.
To take this running time shift into account, it
is necessary to inform the sensor in the menu
of the tube inner diameter.
In the menu point " Pulse velocity “, it is addi-
tionally possible to set manually a correction
factor for the pulse velocity (light velocity) of
the radar signal.
