DEF Sensors
TE Connectivity (TE) offers distinct technologies to measure fluids. Our tuning fork technology is coupled with efficient software algorithms for accurate measurement of viscosity, density and dielectric constant. Dedicated applications include oils (engine, hydraulic, transmission), fluid monitoring, and others. Our urea quality sensors, based on Ultrasonic Technology (UST), perform an analysis of the Diesel Exhaust Fluid (DEF) fluid to provide urea concentration and secure mis-filling protection to the Selective Catalytic Reduction (SCR) systems. Our highly reliable reed switch technology is combined with temperature measurement for level sensing.
