DEF Level Sender with Quality Sensor

The DEF Level Sending unit is used in Selective Catalytic Reduction (SCR) system to reduce emissions pollutants such as NOx (generic term for NO, nitric oxide, and NO2, nitrogen dioxide) from the engine exhaust gas. The DEF Sending Unit integrates liquid level and temperature measurement functions, as well as a heating function utilizing the engine’s coolant. Quality Sensors are integrated into the DEF Level Sending Unit to ensure the DEF concentration are at the correct level for SCR system’s operational efficiency.
