NOx Exhaust Sensors

Nitrogen oxide sensors (NOx Sensor) are typically a high-temperature sensor built to detect high levels of nitrogen oxides within exhaust emissions of an automotive vehicle.

Many governments around the world have passed laws to limit NOx emissions (along with other combustion gases and hydrocarbons), so these types of sensors and gases monitoring devices are now common. Sensing the gases is only half of the process... the reason these devices are in place is to trigger re-processing, or loop-back systems within the vehicle if high levels NOx levels are found.
