Abstract: Rauchmelder, umfassend eine Detektorkammer, einen Einlaß zum Einleiten eines zu messenden Luftstroms in die Kammer, einen Auslaß für den Luftstrom aus der Kammer, Einrichtungen für die Erzeugung eines Lichtstrahls innerhalb der Kammer, einen Streulichtdetektor, der auf die Gegenwart von Streulicht innerhalb einer Zone der Kammer infolge der Gegenwart von Rauchteilchen innerhalb des zu messenden Luftstroms in der Zone anspricht, einen Lichtabsorber an einem Ende der Kammer, das von der Lichtquelle entfernt ist, zur Aufnahme und Absorbtion des Strahls nach dem Durchgang durch die Kammer, eine erste Kollimatorscheibe zum Kollimieren des Strahls und eine zweite Kollimatorscheibe hinter der ersten Kollimatorscheibe, wobei die zweite Kollimatorscheibe eine Öffnung mit einer solchen Größe aufweist, dass der durch die erste Kollimatorscheibe kollimierte Strahl durch die Öffnung in der Kollimatorscheibe tritt, ohne den Rand der Öffnung zu berühren, wobei die Öffnung der zweiten Kollimatorscheibe größer als die Öffnung der ersten Kollimatorscheibe ist und die zweite Kollimatorscheibe dazu dient, Lichtschimmer abzufangen, die vom Rand der ersten Kollimatorscheibe stammen, und dadurch Störlicht in der Zone, in der der Nachweis der Lichtstreuung stattfindet, zu reduzieren und der Rauchmelder noch eine weitere Kollimatorscheibe umfasst, die sich hinter der zweiten Kollimatorscheibe befindet und eine Öffnung hat, die größer ist als die Öffnung der zweiten Kollimatorscheibe, so dass der durch die Öffnung in der zweiten Kollimatorscheibe hindurch tretende Strahl auch durch die Öffnung in der weiteren ...

Abstract: A method of particle detection in an aspirated particle detection system, the system having a sampling pipe network and a particle detector. The sampling pipe network includes at least one sampling pipe in fluid communication with the particle detector, a plurality of sampling inlets through which sample air can enter the at least one sampling pipe, and an opening in the at least one sampling pipe upstream of the plurality of sampling inlets, wherein the opening has lower flow impedance than any one of the sampling inlets. The method includes drawing sample air to the particle detector through the air sampling network; analysing the sample air with the particle detector; entering an amplification phase, in the event that a concentration of particles in the sample air greater than a predetermined threshold is detected, to create a plurality of sample air packets in the sampling pipe, wherein each sample air packet corresponds to a sampling inlet and includes an amplified concentration of air drawn from the corresponding sampling inlet; transporting the sample air including the plurality of sample air packets through the sampling pipe to the particle detector; and determining through which sampling inlet any particles entered the particle detection system.

Abstract: An air sampling system (10, 110) for a low-temperature space (12) is disclosed. The air sampling system (10, 110) includes: an air sampling pipe (16) for passing sampling air to an air sampling device (2); and a sampling conduit (20, 120) extending from the low-temperature space (12) to outside the low-temperature space (12). The sampling conduit (20, 120) is connected to the sampling pipe (16), wherein the sampling conduit (20, 120) is selectively accessible from outside the low-temperature space (12) for removal of ice build-up within the sampling conduit (20, 120). Also disclosed is a kit for an air sampling system. Also disclosed is a method, computing system, air-sampling device and air monitoring system that evaluates an air sampling network.

Abstract: A particle detection system including; at least one light source adapted to illuminate a volume being monitored at at least two wavelengths; a receiver having a field of view and being adapted to receive light from at least one light source after said light has traversed the volume being monitored 5 and being adapted to generate signals indicative of the intensity oflight received at regions within the field of view of the receiver; a processor associated with the receiver adapted to process the signals generated by the receiver to correlate light received at at least two wavelengths in corresponding regions within the field of view of the receiver and generate an output indicative of the relative level of light re- ceived at the two wavelengths.
