DEF Level Sensors and SCR Sensors

TE Connectivity (TE) offers distinct fluid property sensor 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 for our DEF sensors include oils quality sensors (engine, hydraulic, transmission), fluid monitoring, and others. Our urea quality SCR 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 systems. Our highly reliable reed switch technology is combined with temperature measurement for DEF level sensing.
