42 Capacitive electrodes EK - Profibus PA
Setup
If you have chosen pF, you can assign a
corresponding value in pF to the percentage
value.
Example
0 % = 97,2 pF
100 % = 1428.0 pF
The values for the adjustment will be
accepted by pushing the button OK.
Conditioning
The following functions are available in this
window:
- Scaling
- Linearisation
- Integration time
Scaling
With this button, a message appears telling
you that for Profibus sensors, this function
can be found in the menu window "Instrument
data parameter adjustment" under menu
point "Output". Carry out the scaling there.
Linearisation
In this window, you can linearise non-linear
vessels, such as e.g. a cyindrical tank. The
following linearisation curves are available:
- linear
- cylindrical tank
- spherical tank
- user-programmable curve
Click in the window "Instrument data
parameter adjustment" to
Conditioning .
Click in the window "Conditioning" to
Linearisation.
With oscillator CAP E34 PA Ex you can also
enter your own linearisation curve for special
vessels, e.g. cylindrical vessel with large
funnel-shaped outlet, under "user-
programmable curve".
Push the button Edit. You can enter the value
pairs (percentage value - volume value) for
32 index markers.
