FGH NOx 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.
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 is high levels are found, commonly referred to as combustion optimization or regeneration of NOx traps.
Many governments around the world have passed laws to limit NOx emissions (along with other combustion gases such as SOx (oxides of sulfur), CO (carbon monoxide) and CO2 (carbon dioxide) and hydrocarbons), so these types of sensors and gases monitoring devices will become increasingly common.
