What We Do?
VexoTECH is a vertically integrated developer and manufacturer of NOx sensors and sensor core materials, with over 17 years of experience spanning ceramic materials, sensor chips, electronics, and complete sensor assemblies.
Our NOx sensors are designed for diesel engine exhaust aftertreatment systems (SCR) and support:
- Heavy-duty on-highway trucks
- Off-highway equipment
- Automotive programs
- Engineering development and validation
- Global aftermarket applications
NOx Sensor Systems
VexoTECH NOx sensors consist of a high-temperature ceramic probe and an electronic control unit (controller), connected by a cable.
The probe converts nitrogen oxides in exhaust gas into electrical signals. These signals are processed by the controller using proprietary algorithms and transmitted digitally via CAN-based protocols (e.g., J1939) to support emissions monitoring and SCR control.
