Abstract

Die Erfindung betrifft einen Ionisationsrauchmelder zur Erfassung von Rauchearosolen bei der Entstehung von Bränden mit wenigsten drei gegeneinander isolierten Elektroden (1, 2, 4), wobei mindestens eine Elektrode als Ionisierungselektrode (4) und mindestens 2 Elektroden als hohlzylindrische Gegenelektroden (1, 3) ausgebildet sind. Die Gegenelektroden bilden gemeinsam mit den an ihren Grundflächen angeordneten Isolatoren (2, 7) die ein Gasvolumen einschließende Meßkammer (17) und Referenzkammer (18).
Beide Kammern(17, 18) sind über eine Ausgleichsöffnung (8) miteinander verbunden, welche insbesondere zum Gasaustausch (Diffusion) und damit zur Herstellung gleicher Gasverhältnisse dient.
Erfindungsgemäß ist die Ionisationselektrode (4) einstückig ausgebildet und läuft durch die Meßkammer (17) und durch die Referenzkammer (18).
Dadurch ist es möglich, in beiden Kammern homogene proportionale elektrische Feldverhältnisse für die Ionenerzeugung herzustellen.
Die erfindungsgemäße Schaltungsanordnung (15) zur Stromversorgung verbessert besonders die Reproduzierbarkeit und die Genauigkeit der Meßergebnisse.
