Core competence: Fluid properties sensor

Fluid properties sensors help to measure the concentration and ratios in different liquids (AdBlue®, DEF, Urea) using an optical measuring principle. This highly robust sensor can be used in multiple applications. It offers a high degree of accuracy and temperature resistance.



Typical features and benefits

  • Measuring liquid concentration
  • Concentration ratio of different liquids
  • Wear-free
  • Accuracy: ± 2 % (concentration of urea in water)
  • Measurement range: 0 % - 50 % (urea in water)
  • Function: -40 °C to + 60 °C (85 °C)
  • Signal output: SENT interface
  • Optical measuring principle
  • Tank assembly, frost-resistant
  • Temperature signal
  • Connector type optional
