Adapting the measuring device to the process conditions
8.1.1
Applications
The "Absorption" and "Formazine" applications are calibrated at the factory. The absorption
factory calibration is used as the basis for precalibrating additional applications and
optimizing them for the different media characteristics.
Application
Specified operating range
Factory calibration for absorption
0.000 to 5.000 AU or
0.000 to 10.000 OD
Factory calibration for formazine
40 to 4,000 FAU
Application: Kaolin
0 to 60 g/l
Application: Sludge
0 to 25 g/l
Application: Auto sludge
0 to 25 g/l
Product loss
0 to 100 %
To adapt to a specific application, it is possible to perform customer calibrations with up to 10
points.
Application: Formazine
Factory calibration for the formazine application is carried out with the formazine turbidity
standard.
Sensor measured values in the unit [FAU] are only comparable to the measured values of
any other sensor e.g. scattered light sensor with the unit [FNU] or [NTU] in this standard
medium. In any other medium, the measured values will be different to those obtained
when measuring with another scattered light sensor.
8.1.2
Calibration
The absorption and formazine applications are calibrated at the factory. All other applications
are merely precalibrated and must therefore be adapted to the corresponding application and
medium.
The sensor has 8 data records. Six of these are prepopulated at the factory with sample data
records, i.e. typical settings, for all available applications:
• Absorption
• Formazine
• Kaolin
• Sludge
• Auto sludge
• Product loss
