Abstract: There is describes a filter arrangement (10) for a particle detector (12) for detecting particles in an environment. The particle detector (12) can include one or more sensors (30) for analysing fluid in a detection region to produce sensor output. The filter arrangement (30) includes structure defining flow paths, for conveying fluid from the environment towards the detection region, including a first flow path (22), which includes a filter(26), and a second flow path (24) bypassing the filter(10). There is also provided a mechanism (120B) for controlling relative flow rates of fluid through the first flow path (22) and the second flow path (24) and a controller (32) configured to receive the sensor output corresponding to at least two relative flow rates and apply logic thereto to generate an output indicative of a condition of the filter.

Abstract: A METHOD OF DETECTING PARTICLES IN AN AIR FLOW IS DESCRIBED.THE METHOD INCLUDES RECEIVING A SIGNAL INDICATIVE OF LIGHT INTENSITY SCATTERED FROM THE AIR FLOW AT A PLURALITY OF WAVELENGTHS AND PROCESSING THE SIGNAL INDICATIVE OF THE INTENSITY OF RECEIVED LIGHT AT EACH OF THE WAVELENGTHS AND A CORRESPONDING WAVELENGTH DEPENDENT PARAMETER TO GENERATE AN OUTPUT SIGNAL INDICATIVE OF AT LEAST ONE CHARACTERISTIC OF PARTICLES IN THE AIR FLOW.A PARTICLE DETECTION SYSTEM IS ALSO DESCRIBED.

Abstract: A method of detecting particles in an air flow is described. The method includes receiving a signal indicative of light intensity scattered from the air flow at a plurality of wavelengths and processing the signal indicative of the intensity of received light at each of the wavelengths and a corresponding wavelength dependent parameter to generate an output signal indicative of at least one characteristic of particles in the air flow. A particle detection system is also described.
