Abstract

Die Erfindung betrifft eine Vorrichtung zum Erkennen von Glimmnestern 1 in einer pneumatischen Förderleitung 2 mit IR-Sensoren 4, die auf einem Verdrängungskörper 3 angeordnet sind. Um die IR-Sensoren gegen Verschmutzungen und Beschädigungen zu schützen und somit einen dauerhaft zuverlässigen Betrieb der Vorrichtung zu ermöglichen, wird vorgeschlagen, die IR-Sensoren 4 im Innern einer längserstreckten Hülse 7 anzuordnen.
