VEGAPULS 65 • 4 … 20 mA/HART - four-wire
36516-EN-121011
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
•
Process/measurement conditions:
– Measured value jumps, e.g. by truck loading
– Fast reaction time
– Large distance to the medium
Demonstration:
•
Adjustment for all applications which are not typically level meas-
urement
•
Sensor accepts all measured value changes within the measuring
range immediately
•
Typical applications:
– Instrument demonstration
– Object recognition/monitoring (additional settings required)
Through this selection, the sensor is adapted optimally to the applica-
tion or the location and measurement reliability under the various
basic conditions is increased considerably.
