In order to achieve efficient exhaust gas treatment, exhaust systems need accurate and up-to-date data. Stricter emission regulations in particular require the use of additional sensors, including nitrogen oxygen sensors (NOx sensors). It is used to control the amount of urea that needs to be injected in the SCR system to reduce nitrogen oxides, and it is also used to monitor (on-board diagnostic systems) SCR components. Nitrogen oxygen sensors are typically installed downstream of the SCR catalytic converter or, depending on the application, upstream of the SCR catalytic converter to measure the nitrogen oxide content in the exhaust gas. The NOX sensor communicates with the engine control unit via the CAN bus. At the heart of the NOX sensor is a ceramic substrate sensing element, the measuring principle of which is based on the output current of the reaction chamber of the dual-neunest unit.
MAAX is a Chinese manufacturer specializing in OE-grade nitrogen oxygen sensors（NOx sensors), offering two generations (1st and 2nd) of sensors that can be used in passenger cars, light vehicles, and commercial vehicles (on-road or off-road use) as well as supporting 12V and 24V power supplies. MAAX offers a low MOQ and fast delivery, which decreases customers cargo stock and cash pressure, while our extensive product coverage meets customer needs widely. Also customers could get benifits from the outstanding OE quality NOx sensor as below :
1. Comply with current and future emission limits and on-board diagnostics regulations
2. High measurement accuracy, fast readiness, good dynamic response, continuous signal output
3. It can be flexibly matched with the CAN interface
4. Due to the protective layer of the sensor unit, it can withstand external environmental influences.Such as thermal shock
5. High resistance to external environmental influences, longer service life and better reliability
