Setup - Vessel height,
measuring range
Setup - Vessel form
LEVEL TRANSMITTER 8136 • 4 ... 20 mA/HART - two-wire
•
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
•
Properties, sensor:
– Mean averaging
– High measured value jumps are accepted
Crusher:
•
Vessel: installations, wear and protective facilities available
•
Process/measurement conditions:
– Measured value jumps, e.g. through truck loading
– Fast reaction time
– Large distance to the medium
•
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 against interferences, because virtually no
averaging
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.
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.
With this selection, the operating range of the sensor is adapted to
the vessel height and the reliability with different frame conditions is
increased considerably.
The min. adjustment must be carried out independently of this.
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.
Also the vessel form can influence the measurement apart from the
medium and the application. To adapt the sensor to these measure-
