  FPS2851ULC4 – Urea Quality Sensor

Click to Download a PDF for this Product

Relying on patented tuning fork technology, our MEAS multi parameter urea sensor measures urea concentration, identifies urea quality and urea temperature of DEF used in SCR systems. The optimized in-line mounted urea quality sensor provides real-time multi-parametric analysis DEF and utilizes high performance algorithms to provide direct feedback to urea feed dosing systems or ECMs to optimize emission control for NOx reduction. Thus the UQS is an important tool for meeting regulated OBD compliance to confirm urea presence and concentration, security signal communication. Emissions compliance with JP 09, EPA 10, Tier IV and EURO VI is ensured with our platform technology. Further, due to the sensor's performance capabilities to monitor DEF solutions (e.g, AdBlue®), the sensor performs simultaneously as a urea quality sensor and urea concentration sensor. A universal digital CAN J1939 compliant protocol provides easy to connect interface to main control systems (i.e., ECM, SCR feed control, OBD bus). Options to support J2284 interfacing are available. A simple 4 pin connector allows cost effective mounting options.
