Product Details
Particulate Matter Sensor KGD - 326 for Measuring Diesel Particles
Product Introduction
The particulate matter sensor KGD - 326 is used to measure the
cumulative particulate matter (soot) mass in the exhaust gas at the
rear end of a Diesel Particulate Filter (DPF) to determine the
efficiency of the DPF. The particulate matter sensor is located on
the pipeline of the Selective Catalytic Reduction (SCR) catalyst
and consists of a probe and an electronic control module. This
module communicates and shares information with the Powertrain
Control Module (PCM) via the J1939 data link. The probe contains
three internal components: a heater, a temperature sensor, and a
set of high - resistance particulate matter measuring electrodes.
Product Features
- Compact sensor design
- Integrated structure of sensing element and heater significantly
improves the light - off efficiency
- Equipped with Resistance Temperature Detector (RTD) element
- Allows closed - loop heater control for accurate sensor
regeneration
- Reliable diagnostic capabilities
