VEGAPULS C 21 • Modbus and Levelmaster protocol
58343-EN-200806
Demonstration
•
Applications that are not typical level measurements, e.g. device
tests
– Instrument demonstration
– Object recognition/monitoring
– Fast position changes of a measuring plate during functional
test
With " Bulk solid", the applications are based on the following fea-
tures, to which the measuring characteristic of the sensor is adjusted
in particular:
Silo (slender and high)
•
Process/measurement conditions:
– Interferingreectionsduetoweldseamsonthevessel
– Multipleechoes/diusereectionsduetounfavourablepouring
positionswithnegrain
– Varyingpouringpositionsduetooutletfunnelandllingcone
•
Further recommendations
– False signal suppression via adjustment app or PACTware/DTM
– Alignment of the measurement to the silo outlet
Bunker (large-volume)
•
Process/measurement conditions:
– Large distance to the medium
– Steep angles of repose, unfavourable pouring positions due to
outletfunnelandllingcone
– Diusereectionsduetostructuredvesselwallsorinternals
– Multipleechoes/diusereectionsduetounfavourablepouring
positionswithnegrain
– Changing signal conditions when large amounts of material slip
o
•
Further recommendations
– False signal suppression via adjustment app or PACTware/DTM
Heap(pointmeasurement/proledetection)
•
Process/measurement conditions:
– Measuredvaluejumps,e.g.throughheapproleandtraverses
– Large angles of repose, varying pouring positions
– Measurementnearthellingstream
– Sensor mounting on movable conveyor belts
Crusher
•
Process/measurement conditions:
– Measured value jumps and varying pouring positions, e.g. due
totrucklling
– Fast reaction time
– Large distance to the medium
– Interferingreectionsfromxturesorprotectivedevices
•
Further recommendations
– False signal suppression via adjustment app or PACTware/DTM
