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.
