Abstract

Die Erfindung betrifft einen Gefahrenmelder (1) zur Überwachung von dessen Umgebung im Hinblick auf eine Gefahrengröße, mit wenigstens einem Sensorelement (2), welches wenigstens einen Gassensor (3, 4) aufweist, der eine Konzentration von Partikeln eines Gases in der Umgebungsluft des Gefahrenmelders (1) misst, wobei das Sensorelement (2) im Innern einer zumindest bereichsweise für die Partikel durchlässigen Elementhülle (7) angeordnet ist, durch welche die Partikel vor ihrer Erfassung durch den wenigstens einen Gassensor (3, 4) treten. Um einen Gefahrenmelder (1) zur Verfügung zu haben, mittels dessen mit geringem Aufwand feststellbar ist, ob der wenigstens eine Gassensor (3, 4) des Sensorelements durch die von ihm zu erfassenden Partikel im wesentlichen ungehindert erreichbar ist, ist das Sensorelement 2 mit wenigstens einem weiteren Sensor (5, 6) zur gemeinsamen Anordnung mit dem wenigstens einen Gassensor (3, 4) innerhalb der Elementhülle (7) vorgesehen, der wenigstens eine weitere Sensor (5, 6) erfasst eine von der Partikelkonzentration des Gases verschiedene Messgröße, anhand von deren Schwankungsbreite der Gefahrenmelder (1) die Durchlässigkeit des durchlässigen Bereichs (8) der Elementhülle (7) beurteilt.

The invention relates to a hazard detector (1) for monitoring its surroundings with regard to a hazard quantity, comprising at least one sensor element (2) which has at least one gas sensor (3, 4) which has a concentration of particles of a gas in the ambient air of the danger detector (1) measures, wherein the sensor element (2) in the interior of an at least partially permeable to the particles element shell (7) is arranged through which the particles pass through their detection by the at least one gas sensor (3, 4). In order to have a hazard detector (1) by means of which it can be determined with little effort whether the at least one gas sensor (3, 4) of the sensor element can be reached substantially unhindered by the particles to be detected by it, the sensor element 2 is at least a further sensor (5, 6) for common arrangement with the at least one gas sensor (3, 4) provided within the element shell (7), the at least one further sensor (5, 6) detects a different from the particle concentration of the gas measured the permeability of the permeable region (8) of the element envelope (7) is assessed by their range of variation of the danger detector (1).
