Description: The FPS2851ULC4 is a sensor that directly and simultaneously measures all the critical parameters of aqueous urea solution. Relying on patented tuning fork technology, the measurements of urea concentration, temperature enable users to determine if the quality of the employed reducing fluid will enable Selective Catalytic Reduction systems to achieve optimal performance. In-line or in-tank real-time multi-parametric urea analysis allows high performance algorithms to provide direct feedback to urea feed control systems or ECMs to optimize emission control for NOx reduction. The FPS2851ULC4 is an important tool for meeting regulated OBD compliance to confirm urea presence and concentration, security signal communication. A universal digital CAN J1939 compliant protocol provides easy to connect interface to main control systems (i.e., ECM, SCR feed control, OBD bus). A simple 4 pin connector allows cost effective mounting options.
