AdBlue Quality Sensors

 Precision Urea Monitoring for Optimal SCR Performance  

Key Benefits of CAMT’s AdBlue Sensors

Accurate Urea Concentration Monitoring

AdBlue (Diesel Exhaust Fluid) must maintain a precise urea-to-water ratio of 32.5% to function effectively in SCR systems. CAMT’s AdBlue sensors use ultrasonic and conductivity-based detection to provide real-time measurement of fluid quality, ensuring that only properly mixed AdBlue is injected into the exhaust stream. This accuracy helps prevent inefficient NOx reduction, excessive ammonia slip, and costly vehicle downtime due to poor fluid quality.  

Reliable Performance in Extreme Conditions

SCR systems operate in demanding environments, often exposed to high temperatures, freezing conditions, vibrations, and harsh chemicals. CAMT’s AdBlue sensors are built to withstand:

  • Extreme Temperature Ranges – Designed to function in temperatures from -40°C to +85°C, preventing freezing or degradation of urea solutions.
  • Corrosion-Resistant Materials – The sensor’s chemical-resistant polymer housing protects internal components from degradation due to AdBlue’s naturally corrosive properties.
  • Shock and Vibration Durability – Engineered to handle the high-vibration environments of diesel engines and off-road equipment, ensuring consistent performance over time.


Compliant with Global Emission Standards

AdBlue sensors are essential for meeting modern emissions standards, and CAMT’s sensors are designed to align with the latest regulations, including:

  • Euro 6 and Euro 7 Standards – Ensures compliance with stringent NOx reduction mandates for diesel engines in Europe.
  • EPA Requirements – Approved for use in off-highway and commercial vehicles operating in North America.
  • ISO 22241 Compliance – Adheres to strict international standards for Diesel Exhaust Fluid (DEF) quality, handling, and performance.

With CAMT’s AdBlue sensors, vehicle manufacturers and fleet operators can ensure regulatory compliance, optimized SCR efficiency, and reduced environmental impact.

Wide Application Across Diesel Vehicles

CAMT’s AdBlue sensors are designed for seamless integration into a broad range of diesel-powered applications, ensuring effective NOx reduction in:

  • Passenger and Light Commercial Vehicles – Ensures optimal SCR function for reduced NOx emissions in diesel cars, vans, and light trucks.
  • Heavy-Duty Trucks & Buses – Maintains compliance and performance in long-haul and public transportation applications.
  • Off-Highway and Industrial Equipment – Supports NOx control in construction, mining, and agricultural machinery.
  • Marine & Rail Applications – Engineered for large-scale diesel engines, providing compliance with maritime and rail emissions standards.

By ensuring AdBlue quality and precision in real-time fluid monitoring, CAMT sensors help diesel vehicles and industrial machinery meet strict emission targets while maintaining peak efficiency.


Seamless OEM Integration

CAMT’s AdBlue sensors are designed to integrate effortlessly with OEM and aftermarket SCR systems, providing:

  • Plug-and-Play Compatibility – Matches standard CAN, LIN, and PWM communication protocols, making installation simple.
  • Precise Sensor Calibration – Delivers accurate urea concentration readings that sync perfectly with SCR dosing control.
  • Durable Electrical Connections – Ensures stable signal transmission in high-vibration environments, preventing data loss or faulty readings.
  • Long-Term Sensor Stability – Features advanced signal processing algorithms to minimize drift and measurement errors over time.

With precise, real-time monitoring, CAMT’s AdBlue sensors optimize DEF usage, prevent system failures, and extend the lifespan of exhaust aftertreatment systems
