Accusolve Diesel Particulate Filter (DPF) Soot Sensor
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.
- Provide closed loop control of any filter system where pollutants absorb RF energy
- On-and Off-road Diesel Particulate Filter (DPF) Soot Sensing
