SAMPLE COLLECTING DEVICE FOR DROPLET AND GAS SAMPLING IN NARROW DUCTS OF A GAS TURBINE OR ANY OTHER DEVICE WITH AN OIL BREATHER

摘要

The present invention relates to an analysing arrangement (100) for analysing a composition of a fluid, such as oil mist, of an engine, e.g. a gas turbine. The analysing arrangement (100) comprises a breather pipe (130) which is coupleable to the gas turbine such that at least a part of the fluid is flowing through the breather pipe (130), a first collecting device (110) for collecting a first sample of the fluid, wherein the first collecting device (110) is configured for providing a first composition analysis of the first sample and a second collecting device (120) for collecting a second sample of the fluid, wherein the second collecting device (120) is configured for providing a second composition analysis of the second sample. The first collecting device (110) and the second collecting device (120) are arranged inside the breather pipe (130) such that the first collecting device (110) and the second collecting device (120) are exposed to a common flow characteristic of the fluid inside the breather pipe (130).
