Damping
– extended menu structure
The damping influences the reaction speed of display, output signal and switch output at a change of
the measuring signal.
The behavior of display and output signal follows an exponential characteristic with the damping time
constant t.
Within the time period t the output signal increases respectively by 63% of the existing deviation.
With 99,3%, the end value is nearly achieved after 5 t.
The set time equals 5 t.
The measuring rate depends directly on the set damping.
•
Damping 0s >> Measuring rate 100x/s >> Resolution 12 bit
•
Damping 0,02s >> Measuring rate 50x/s >> Resolution 16 bit
• Damping 0,05s >> Measuring rate 20x/s >> Resolution 18 bit
• Damping 0,15s >> Measuring rate 7,5x/s >> Resolution 20 bit
•
At damping values ≥ 0,15s the resolution remains at 20 bit constantly.
The input range is indefinite.

Linearization
– extended menu structure
Due to the integrated linearization function it is possible, to linearize a measuring signal e.g. for
volume calculation of conical or horizontal cylindrical vessels or also for flow calculation.
A - Tank with linearization points 1 / 2 / 3 / 4
B - Characteristic distance - level not linearized
C - Characteristic distance - level linearized
