Value
Enter a fixed value for the level here. Only visible, if sensor type no. 2 is se-
lected. This value is set to 0.1 m (3.9 in) as standard.
Measurement range
Select between measurement ranges 4-20 mA or 0-20 mA. Only visible,
if sensor type no. 3 is selected.
Value at 0 mA
Enter a level value for 0 mA here.
Only visible if 0-20 mA has been selected as measurement range for sensor
type no. 3. This value is set to 0 m (0.0 in) as standard.
Value at 4 mA
Enter a level value for 4 mA here.
Only visible, if sensor type no. 3 or 4 is selected.
This value is set to 0 m (0.0 in) as standard.
Value at 20 mA
Enter a level value for 20 mA here.
Only visible, if sensor type no. 3 or 4 is selected.
This value is set to 4 m (13.1 ft) as standard.
Offset
This entry will move the zero point of the external sensor. Only visible, if sen-
sor type no. 3 or 4 is selected. This value is set to 0 m (0.0 in) as standard.
Damping
This value is to damp a fluctuating signal of an external level measurement.
Only visible, if sensor type no. 3 or 4 is selected.
This value is set to 0 s as standard and can be set to up to 10 s.
9.4.3 Information on how to connect i-Series sensors
The i-Series sensors feature pre-programmed measurement ranges. Please
refer to the according instruction manual. The sensor can be operated even
without HART modem.
Setting the parameter "Value at 20 mA" requires to enter the measurement
span of the sensor. Depending on the installation height of the sensor a nega-
tive offset value may be additionally necessary.
