DEF Sensor

DEF Sensors are critical monitoring devices designed for diesel exhaust after-treatment systems. These precision instruments integrate temperature, pressure, conductivity, and ultrasonic wave detection technologies to measure Diesel Exhaust Fluid (DEF/AdBlue) concentration and levels.

Built with corrosion-resistant materials, DEF sensors withstand harsh operating environments while providing real-time monitoring for optimal NOx reduction in Selective Catalytic Reduction (SCR) systems. They are widely used in heavy-duty trucks, buses, and construction equipment, offering reliable performance and extended service life.

The sensors ensure precise level detection, accurate concentration measurement, and timely maintenance alerts, delivering superior performance in emissions control while optimizing DEF consumption and maintaining regulatory compliance.
