Thermometrics Accusolve Diesel Particulate Filter (DPF) Soot Sensor utilizes radio frequency technology to enable accurate measurement of accumulated soot in the DPF, providing real-time soot loading data and real time closed loop control of the DPF regeneration process. Accurate measurement of the soot load allows for the optimization and reduction of regeneration cycles of the DPF. This in turn allows for improved fuel economy and improved filter life for active and passive regeneration systems.
Applications
- Provide closed loop control of any filter system where pollutants absorb RF energy
- On-and Off-road Diesel Particulate Filter (DPF) Soot Sensing
- Industrial heavy-duty stationary diesel DPF applications
- Marine diesel DPF
- Rail diesel DPF
- LD truck and Passenger Car diesel engines DPF
Features
-
Accurately and continuously measures soot loading (g/L) within a diesel particulate filter (DPF) and through filter specific algorithms providing a (g/L) reading so the OEM can maintain closed loop control of the DPF regeneration process
-
System cost reductions available due to reduced DPF size and type of materials used
-
Allows multiple regeneration strategies
-
Enables accurate reading of partial regeneration
-
Factory calibration of the sensor via CAN prior to shipment
-
The sensor electronics enclosure dimension is 100 mm x 150 mm x 30 mm.
-
4 sensor configurations available include coaxial cable lengths of 1.0 m, 1.5 m, 2.5 m and 3.0 m.
