Urea Sensor Module for SCR System Monitoring

Product Details:   Product Overview:   The YUN NEI POWER urea sensor module is an electronic monitoring component in the SCR aftertreatment system that measures the quality and concentration of diesel exhaust fluid (DEF) in real time. By continuously verifying that the DEF solution meets the required urea concentration (32.5% ± 0.5%), this sensor ensures the SCR system operates within its optimal emission reduction range. If the sensor detects incorrect concentration or contaminated fluid, it signals the engine control unit to trigger a warning and potentially limit engine performance to prevent non-compliant emissions.   Core Features & Advantages:   Real-time DEF concentration measurement ensures accurate emission control Quality detection identifies contaminated or diluted urea solution before it causes damage Compact modular design allows flexible mounting in the urea supply line or tank Fast response time enables immediate detection of fluid quality changes Compatible with st…
