Measuring range
CUS52D Application
Turbidity 0.000 to 4000 FNU
Display range up to 9999 FNU Formazine
Solids 0 to 600 mg/l
Display range up to 3 g/l Kaolin
0 to 2 200 mg/l
Display range up to 10 g/l
Diatomite
Temperature –20 to 85 °C (–4 to 185 °F)
Factory calibration
The sensor has been calibrated in the factory for "formazine" applications.
Basis: internal 20 point characteristic curve
13.2 Performance characteristics
Reference operating
conditions
20 °C (68 °F), 1013 hPa (15 psi)
Maximum measured error
Turbidity 2 % of the measured value or 0.1 FNU (the greater value applies in each case).
Reference: measured value in recommended operational range, factory
calibration
Solids < 5% of measured value or 1 % of the end of measuring range (the greater
value applies in each case). Applies for sensors that are calibrated to the
particular measuring range under analysis.
The measured error encompasses all inaccuracies of the measuring chain (sensor and
transmitter). However, it does not include the inaccuracy of the reference material
used for calibration.
For solids, the achievable measured errors depend very much on the media that are
actually present and may differ from the specified values. Extremely inhomogeneous
media cause the measured value to fluctuate and increase the measured error.
Repeatability < 0.5 % of the measured value
Long-term reliability Drift
Working on the basis of electronic controls, the sensor is largely free of drifts.
