Particulate measurement as part of the main inspection of diesel vehicles will come into force on January 1, 2023. The counting of soot particles as an integral part of the exhaust emission test of diesel cars. Everything you need to know about our OEM particle measurement technology consisting of a charging module, sensor module, ion separator and Volatile Particle Remover (VPR) comes into play here. The system can be easily cleaned and can be used as a standard solution as well as modularly. This means that adaptation to individual requirements is also no problem. Of course, the particle measuring technology complies with PTB-A specifications and can therefore be used throughout Europe without any worries.
The Volatile Particle Remover (VPR) removes the volatile components in compliance with the law with an effectiveness close to 100%.
Ions are generated in the charger module, which then charge the particles at the mixing point with the exhaust gas. The mixing chamber is integrated in the charging module.
The separator can be operated with different voltages, so that, on the one hand, ions can be left (e.g. for the function test) or separated, but also the particle size distribution can be determined.
The very low currents through the charged particles are measured in the sensor module. Maximum sensitivity and robustness are no contradiction. All our components can be cleaned with compressed air, liquid or a brush, should something go wrong during the measurement.
