Material (2.2.3.)
Automatically configures the device to operate in the chosen application type, by changing one
or more of the following parameters:
Propagation Factor (2.8.3.)
,
Position Detect (2.8.4.2.)
,
and/or
CLEF Range (2.8.4.4.)
.
Options
*
LIQUID
LIQUID LOW DK
a)
(low dielectric liquid - CLEF algorithm enabled)
Related parameters
Propagation Factor (2.8.3.)
Position Detect (2.8.4.2.)
CLEF Range (2.8.4.4.)
a)
dK < 3.0
You can configure each of the related parameters to suit your particular application.
Damping Filter (2.2.4.)
The time constant for the damping filter. The damping filter smooths out the response to a
sudden change in level. This is an exponential filter and the engineering unit is always in
seconds [see Damping (Page 224) for more detail].
Values
Range: 0 to 100.000 s
Default: 10.000 s
Calibration (2.3.)
Note
We recommend using the Quick Start wizard to configure the device.
Low Calibration Pt. (2.3.1.)
Distance from sensor reference point
