VEGAPULS 69 • Two-wire 4 … 20 mA/HART
47247-EN-200427
– Measured value jumps, e.g. through truck loading
– Large distance to the medium
– Large angles of repose
•
Properties, sensor:
– Lower averaging
– Very high measured value jumps are accepted
Heap:
•
Process/measurement conditions:
– Measured value jumps, e.g. by the profile of the heap or trav-
erses
– Large angles of repose
– Measurement near the filling stream
– Sensor mounting on movable conveyor belts
•
Properties, sensor:
– Mean averaging
– High measured value jumps are accepted
Crusher:
•
Process/measurement conditions:
– Measured value jumps, e.g. through truck loading
– Fast reaction time
– Large distance to the medium
– Interfering reflections due to internal installations or wear and
protective devices
•
Properties, sensor:
– Little averaging
– Max. reaction speed, very high measured value jumps are
accepted
Demonstration:
•
Adjustment for all applications which are not typically level meas-
urement
– Instrument demonstration
– Object recognition/monitoring (additional settings required)
•
Properties, sensor:
– Sensor accepts all measured value changes within the measur-
ing range immediately
– High sensitivity to interference, because virtually no averaging
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.
Since the radar sensor is a distance measuring instrument, the
distance from the sensor to the medium surface is measured. To
indicate the actual level, an allocation of the measured distance to the
percentage height must be carried out.
To perform the adjustment, enter the distance with full and empty ves-
sel, see the following example:
