Thermometrics Accusolve Diesel Particulate Filter Soot Sensor DPF

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.
