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
features, to which the measuring characteristic of the sensor is
adjusted in particular:
Silo (slender and high)
•
Process/measurement conditions:
–
Interfering reflections due to weld seams on the vessel
–
Multiple echoes/diffuse reflections due to unfavourable pour-
ing positions with fine grain
–
Varying pouring positions due to outlet funnel and filling cone
•
Further recommendations
–
False signal suppression via the operating tool
–
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 filling cone
–
Diffuse reflections due to structured vessel walls or internals
–
Multiple echoes/diffuse reflections due to unfavourable pour-
ing positions with fine grain
–
Changing signal conditions when large amounts of material
slip off
•
Further recommendations
–
False signal suppression via the operating tool
Heap (point measurement/profile detection)
•
Process/measurement conditions:
–
Measured value jumps, e.g. through heap profile and trav-
erses
–
Large angles of repose, varying pouring positions
–
Measurement near the filling stream
–
Sensor mounting on movable conveyor belts
Crusher
•
Process/measurement conditions:
–
Measured value jumps and varying pouring positions, e.g. due
to truck filling
–
Fast reaction time
–
Large distance to the medium
–
Interfering reflections from fixtures or protective devices
