GB-33
Allocation of the signal output range (4 ... 20 mA) to the desired
pressure measurement range or level measurement range.
Also damping: timely communication of the measurement sig-
nal; rise time of the current output signal after a signal surge
Conversion of the output signal from 4 ... 20 mA to 20 ... 4 mA
signed
Start of the pressure measurement range
Also configuration: programming of the relevant parameters
and the pressure measurement range specific to the application
and measurement location.
The programmed pressure measurement range
The highest pressure value of the programmed measurement
span (end-point of the span)
Determination of approximate volume/pressure ratio values
with non-linear correlations based on varying container designs
For example, a non-linear correlation exists between the fill lev-
el and the volume in spherical containers. During linearization,
the non-linear volume is assigned the 4 ... 20 mA output signal
from a table of values (proximity process by means of up to 32
support points).
The sensor parameters are pre-programmed by the manufac-
turer
