The NOx sensor 5WK9 6642B is part of a NOx reduction aftertreatment system in diesel vehicles using a urea-based SCR system. In 5WK9 6642B NOX sensors, NOX is separated into nitrogen and oxygen by catalytically active electrodes. The NOx sensor 5WK9 6642B can simultaneously measure and exhaust NOx, which can quickly and accurately detect the NOx concentration level in the gas.
NOx Sensor OEM No.5WK9 6642B
NOx sensor measures the NOx upstream and downstream of the SCR catalyst to control the Urea dosing and to diagnose the operation of the SCR system. For passenger cars / light duty / medium duty / heavy duty / buses / special vehicles.
