Fixed temperature
Sets a fixed temperature value if a temperature sensing device is not used.
Setting
Default
This parameter is only visible when parameter "Temperature source" is set to "Fixed
temperature".
Enter the temperature (in °C) of the atmosphere within the transducer acoustic beam. If the
temperature varies with distance from the transducer, enter the average temperature.
Step: Calibration
Current at lower calibration point
Sets loop current produced by the mA input when material is at lower calibration point.
Setting
Default
This parameter is only visible when the sensor type is set to "4 ... 20 mA".
Current at upper calibration point
Sets loop current produced by the mA input when material is at upper calibration point.
Setting
Default
This parameter is only visible when the sensor type is set to "4 ... 20 mA".
Lower calibration point
Sets distance from sensor reference point to lower calibration point: usually process empty
level.
Setting
Default
Upper calibration point
Sets distance from sensor reference point to upper calibration point: usually process full level.
Setting
