Caution:
If a separation of liquids with different dielectric figure occurs in the
vessel, for example through condensation, the radar sensor can
detect under certain circumstances only the medium with the higher
dielectric figure. Keep in mind that layer interfaces can cause faulty
measurements.
If you want to measure the total height of both liquids reliably, please
contact our service department or use an instrument specially de-
signed for interface measurement.
The following options are available when "Bulk solid" is selected:
The following features form the basis of the applications:
Silo (slim and high):
•
Vessel of metal: weld joints
•
Process/measurement conditions:
– Filling too close to the sensor
– System noise with completely empty silo increased
– Automatic false signal suppression with partly filled vessel
Bunker (large-volumed):
•
Vessel of concrete or metal:
– Structured vessel walls
– Installations present
•
Process/measurement conditions:
– Large distance to the medium
– Large angles of repose
Bunker with fast filling:
•
Vessel of concrete or metal, also multiple chamber silo:
– Structured vessel walls
– Installations present
•
Process/measurement conditions:
– Measured value jumps, e.g. by truck loading
– Large distance to the medium
– Large angles of repose
Heap:
•
Sensor mounting on movable conveyor belts
•
Detection of the heap profile
•
Height detection during filling
•
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
Crusher:
•
Vessel: installations, wear and protective facilities available
