Dongfeng 3690610-H0101 Urea Level Sensor Assembly

The 3690610-H0101 urea level sensor is designed for integration into the Selective Catalytic Reduction (SCR) system of Dongfeng Yuhu semi-trailers. It utilizes ultrasonic measurement technology to provide accurate diesel exhaust fluid (DEF/AdBlue) level detection within the storage tank. The sensor assembly includes the level sensing element, temperature thermistor, and integrated connector interface. It operates on a 24V DC vehicle electrical system and communicates via standard PWM or analog signal protocols to the SCR dosing control unit. The housing is constructed from chemical-resistant polymers compatible with 32.5% urea solution. This component meets Euro IV and Euro V emission regulation requirements for on-road heavy-duty commercial vehicles. Direct OEM replacement for Dongfeng part number 3690610-H0101.
