New Sensor Principle for NOx Measurement

Measuring Techniques

Due to increasingly stricter emission limits the measurement of Nitrogen Oxides (NOx) has become more challenging over the last few years. Based on these constraints six medium-sized enterprises and research institutions started the development of a new NOx sensor type for non-road mobile machinery (NRMM) diesel engines. The concept is based on an electrochemical cell. Its simplified structure provides fast response while avoiding cross-sensitivities. This sensor principle allows a more efficient control of exhaust aftertreatment systems in order to fulfill more stringent emission standards.


During the combustion process of fossil fuel Nitrogen Oxides (NOx) are generated. In higher concentrations they have a negative influence on human health. The emission limits for NOx have been reduced continuously over the past years. For example the NOx limit of the emission standards relevant for non-road mobile machinery (NRMM) has been reduced by about 95 % since 1998 [1]. With the...

The new sensor will be developed jointly by six medium-sized enterprises and research institutions funded by the Federal Ministry of Economics ZIM network NOx Arbeitsmobil. The authors are grateful for the promotion by the Federal Ministry of Economics.
