9.2 Warranty Conditions
The pressure transmitter has a 3 year warranty.
9.3 Glossary
Adjustment Allocation of the signal output range (4 ... 20 mA) to the desired
pressure measurement range or level measurement range.
Integration Also dampening: timely communication of the measurement
signal; rise time of the current output signal after a signal surge
Inversion Conversion of the output signal from 4 ... 20 mA to 20 ... 4 mA
Nom. pressure range The operating pressure range for which the sensor was de-
signed
Zero point Start o
f the pressure measurement range
Parameterization Also configuration: programming of the relevant parameters
and the pressure measurement range specific to the application
and measurement location.
Span The programmed pressure measurement range
Span end point The highest pressure value of the programmed measurement
span (end-point of the span)
Tank linearization Determination of approximate volume/pressure ratio values
with non-linear correlatio
ns 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).
Defaults The sensor parameters are pre-programmed by the manufac-
turer
