MEASUREMENT SENSOR OF PARTICLE MATTER IN EXHAUST GAS OF VEHICLE

摘要

PURPOSE: A sensor for measuring particles in exhaust gas of a vehicle is provided to measure the concentration of the particles without a suction device as the particles flow into the sensor by a flow velocity. CONSTITUTION: A sensor for measuring particles in exhaust gas of a vehicle comprises an inflow unit(200), a charging unit(300), and a detection unit(500). The inflow unit is installed in an exhaust pipe(100), and the particles in the exhaust gas flow into the inflow unit. The charging unit charges the particles with a single pole. The particles pass through the detection unit, and the detection unit detects the number concentration of the particles by detecting voltage changes.
