Dongfeng 3690610-K46H0 Urea Level Temperature Sensor Assembly

This urea level and temperature sensor assembly is designed for the Selective Catalytic Reduction (SCR) system on Dongfeng heavy-duty trucks meeting Euro IV and Euro V emission standards. The unit integrates a level sensor and temperature transducer into a single probe assembly for installation in the Diesel Exhaust Fluid (DEF) tank. The sensor provides real-time urea solution level and temperature data to the Engine Control Module (ECM) for precise dosing control and freeze protection strategies. It is engineered for direct fitment on Dongfeng Tianlong and Tianjin series trucks equipped with Tianjin Cummins engines. The housing is constructed from chemical-resistant polymers compatible with AUS32/AdBlue fluid. Electrical connection utilizes a sealed automotive connector meeting IP69K protection standards for harsh under-chassis environments.
