The RF-DPF particulate filter sensor from Filter Sensing Technologies Inc. is a fully-integrated sensing and control unit, capable of measuring soot and ash levels in diesel particulate filters (DPF) and providing direct feedback control of the aftertreatment system.
- For on-vehicle sensing and control in a wide range of applications including off-road equipment such as construction and agriculture and on-highway trucks, buses and other vehicles
- Provides real-time measurements and feedback control based on filter soot and ash levels
- Can be used in OEM and retrofit applications
- Reduces engine fuel consumption through optimized regeneration intervals
- Offers advanced diagnostics with powerful DPF measurement capabilities
- Lowers maintenance costs by measuring ash directly, cleaning the DPF only when needed
- Extends component life by minimizing high temperature regenerations
- Reduces system costs by utilizing smaller or less expensive filters via improved sensing
- Helps provide faster development times by decreasing the resources needed for DPF calibration
- System hardware and software can be customized to meet specific customer requirements
- Hardware consists of RF control unit with a 102 x 105 mm footprint
- RF measurement probe is similar in size to stock temperature sensor
- RF operates with either single or dual probe configuration for vector measurements over broad frequency range from 0.4 to 2.4 GHz, and is user configurable
- Includes built-in and automated OSL calibration, auto-zero function DPF normalization, and integrated sensor self-diagnostics
- Communicates via CAN J1939, analog output 0 to 5V, USB 2.0, or wirelessly with up to 16 GB of internal data storage
- Sensor inputs include two SMA RF ports, two RTD temperature sensor inputs, two thermocouple temperature sensor inputs, and up to four analog input channels
