Abstract: A particle sensing apparatus is provided for determining particle concentration in a fluid, e.g. air. The apparatus is based on fluid-flow passageway having an upstream inlet to receive the fluid and a downstream outlet to exhaust the fluid. It also includes a recirculation passageway in fluid communication with the fluid-flow passageway. Between them, the fluid-flow passageway and the recirculation passageway define a recirculation loop. A first particle sensor is located in the recirculation loop, and other sensors may also be present at other options. A force applicator is included in the fluid-flow passageway to apply a force to the particles entrained in the fluid. The force is used to direct some or all of the particles into the recirculation loop. This provides a choice between increasing the detection limit or the detection range. A processor determines the concentration of particles in the fluid based on the concentration of particles detected at the first particle sensor.
