Abstract
The invention provides a sensor device which comprises an input flow channel () for receiving a gas flow with entrained matter to be sensed. A thermophoretic arrangement () is used to induce a thermophoretic particle movement from a first, warmer, region () of the input flow channel to a second, cooler, region () of the input flow channel (). A sensor () comprises a particle sensor component at or downstream of the first region () of the input flow channel (). The invention provides the benefit of pre-filtering (e.g. removal of most suspended solids/liquids) without the need for a physical filter that can become blocked.
