Title
(DE) VERFAHREN ZUM BETREIBEN EINER KORONA-ENTLADUNGS-PARTIKELSENSOREINHEIT
(EN) METHOD FOR OPERATING A CORONA DISCHARGE PARTICLE SENSOR UNIT
(FR) PROCÉDÉ DE FONCTIONNEMENT D'UNE UNITÉ CAPTEUR DE PARTICULES À EFFLUVE
Abstract
(DE)
Vorgestellt wird ein Verfahren zum Betreiben einer mit einer Korona-Entladung arbeitenden Partikelsensoreinheit (10), die dazu eingerichtet ist, einen Strom von Partikeln in einem mit Partikeln beladenen Fluid mit Hilfe einer steuerbaren Korona-Entladung, deren Korona-Strom und/oder Korona-Spannung durch die Partikelsensoreinheit (10) steuerbar ist, elektrisch aufzuladen und ein von der elektrischen Aufladung und Konzentration der Partikel abhängiges Partikelsensorsignal zu erzeugen. Das Verfahren zeichnet sich dadurch aus, dass die Partikelsensoreinheit (10) so betrieben wird, dass das Partikelsensorsignal in einem vorgebbaren Bereich liegt. Ein unabhängiger Anspruch richtet sich auf eine Partikelsensoreinheit (10).
(EN)
The invention relates to a method for operating a particle sensor unit (10) which operates using a corona discharge and which is designed to electrically charge a flow of particles in a particle-loaded fluid using a controllable corona discharge, the corona current and/or corona voltage of which can be controlled by the particle sensor unit (10), and to generate a particle sensor signal on the basis of the electric charge and concentration of the particles. The method is characterized in that the particle sensor unit (10) is operated such that the particle sensor signal lies in a specifiable range. An independent claim relates to a particle sensor unit (10).
(FR)
L’invention concerne un procédé de fonctionnement d’une unité détecteur de particules (1) à effluve et conçue pour charger électriquement un flux de particules dans un fluide chargé de particules par un effluve contrôlable dont l’intensité d’effluve et/ou la tension d’effluve peut être commandée-s par une unité détecteur de particules et pour générer un signal de détecteur de particules fonction de la charge électrique et de la concentration des particules. Le procédé est caractérisé en ce que l’unité détecteur de particules (10) fonctionne de manière telle que le signal de détecteur de particules soit compris dans une plage prédéfinie. Une revendication indépendante est consacrée à l’unité détecteur de particules (10).
