Benefits

  • High Accuracy and Repeatability:
    Provides stable measurements in mid to high turbidity ranges.
  • Chemical Resistance:
    Low maintenance is required due to the dirt-repellent Teflon derivative used in the sensor head.
  • Robust Design:
    The plastic version of the sensor is suitable for corrosive media or saltwater applications.
  • Fast and Easy Commissioning:
    The sensor is pre-calibrated with various application models and can be adjusted via single-point calibration.
  • Automatic Sludge Model:
    Selects the optimal signal path for different sludge types independently.
  • Perfect Process Adaptation:
    Fast sensor positioning with a wide variety of Endress+Hauser assemblies.
