Turbimax CUS51D
Endress+Hauser 9
Performance characteristics
Maximum measured error
Wavelength 860 ± 30 nm
Factory calibration FNU, FTU and solids concentration according to the application table
Standard: 3 points
Applications The sensor is factory calibrated in the application "formazine" and hereof derived for "kaolin filterable solids)".
Further precalibrated applications are optimized for the corresponding medium.
The calibration can be performed up to 5 points.
Note!
For solids the achievable measuring ranges are depending of the actual medium and can deviate from the
recommended operating ranges. In this case a 3-point-calibration is recommended.
Drift Thanks to electronic control the sensor works drift compensated in a wide range.
Limit of detection
Turbidity < 2% of the measured value or 0.1 FNU (the respectively larger value is valid)
Solids < 5 % of the measured value or 1 % of full scale ( the respectively larger value is valid); valid
for sensors in the calibrated measuring range
