For customers who want to build their own particle counter, we offer a functioning sensor assembly. It can then be installed in its own housing with corresponding, matching electronics, etc. The concept “Modules-in-Flow” gives you the possibility to build a PN-counter with your own housing and periphery.
The Modules-in-Flow assembly is mounted in a flexible arrangement on a base plate in coordination with you, this resulting basic assembly is fully functional and can then, equipped with the appropriate electronics, a housing (e.g. with display) can be built up very quickly and easily to a complete PN counter. We explain the included modules in detail below. Parts like housing, display, probe and sampling, power supply, pump etc. can be requested optionally.
The measured values as well as the statuses of the sensors are provided via a RS232 interface (CAN on request) for further processing.
The size of the base plate and the arrangement of the modules are subject to functional limitations, but we will gladly discuss these with you.
The sensor technology was subjected to type tests in Holland (NMI) and Germany (PTB).
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.
All diesel cars with particulate filters from Euro 6d (approximately from 2021) are subject to particle count measurement during the emissions test. In future, petrol cars with direct injection could also be covered – corresponding pilot projects are already underway.
Our “Modules-in-Flow” are modular sensor assemblies designed for customers who want to build their own particle counters. These pre-assembled modules can be integrated into customer-specific housings with matching electronics, enabling rapid development of a complete particle counter (PN).
The system comprises several key modules:
Charging Module: Generates ions to charge particles in the exhaust gas, featuring clean charging technology to prevent contamination of the corona needle.
Ion/Particle Separator: Separates ions and particles, enabling particle size distribution analysis.
Sensor Module: Measures the induced current from charged particles using a Faraday Cup, ensuring non-contact measurement.
Volatile Particle Remover (VPR): Removes volatile components from the sample, ensuring compliance with legal standards.
These modules are mounted on a base plate and can be customized to fit specific requirements.
The system employs diffusion charging (DC): aerosol particles are ionized via corona discharge, then charged through diffusion. The charged particles induce an electrical current in the Faraday Cup sensor module, which is measured—without consumables or sample gas heating. This enables precise particle counting without the need for emission tester with moving parts.
Many markets are gradually introducing PN measurement or have already integrated it. Concrete requirements are regulated on a country-specific basis. In Germany, particle measurement is already part of the exhaust emission test (AU) carried out as part of the periodical technical inspection (HU).
A particle counter records the number of ultra-fine particles (PN) in the exhaust gas – not the mass. This is particularly effective in detecting defective or manipulated particulate filters.
Yes – we also offer our systems as OEM modules with standardized interfaces (CAN, Modbus, analogue). This means that particle measurement can be easily integrated into existing test benches, software solutions or test devices.
The PNC nano is an extremely reliable particle counter that offers a precise and cost-effective solution for particle measurement and exhaust gas testing.
The PNC nano is a ready-to-use diesel exhaust particle counter that uses Clean Charging Technology and non-contact Faraday cup detection. It complies with PTB-A certification standards and is type-approved in Germany (PTB) and the Netherlands (NMI). Further information can be found here.
A portable, market-ready calibrator combining a stable salt (NaCl) generator and a reference particle counter in one unit. It supports on-site calibration of multiple PN devices, ensuring traceability (EN 17025) and compliance with German AU calibration regulations effective since January 1, 2023. Further information can be found here.
Full-service support includes: initial consulting, OEM customization, integration services, software for guidelines compliance, white papers, user manuals, FAQs, and ongoing maintenance advice. We help you to effectively integrate the particle counter into your vehicle tests and investigations.
