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.

Using special optical techniques, AB Elektronik’s sensor is capable of detecting variances in urea concentration as small as +/- 2 %, and can operate at temperatures from -10 °C to +85 °C. The optical measurement principle is robust against dirt and moving fluids including gasoline, diesel or coolant.
