Description: Our range of UREA/DEF sensors offers design engineers reed switch reliability. The design allows for sensing liquid level along with UREA/DEF temperature and quality. Available in a range of customizable lengths and resistance value outputs to meet your specific tank requirements. The integrated Urea Quality Sensor (UQS) is a sensor that directly and simultaneously measures the chemical properties of aqueous urea solution. Relying on an optical NIR technology, the measurements of urea concentration and temperature enable users to determine if the quality of employed reducing fluid will enable Selective Catalytic Reduction systems to achieve optimal performance. In-tank real time urea analysis allows high performance algorithm to provide both SCR system protection, by differentiating unauthorized fluids, and direct feedback to urea feed control systems or ECMs to optimize emission control for NOx reduction. The UQS is an important tool for meeting regulated OBD compliance to confirm urea presence and concentration and 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 pins connector allows cost effective mounting options. The NIR chemical analysis technology relies on the measurement of fluid chemical bonds to detect unauthorized fluids and allows identification of proper fluid.
