Sample collecting device for droplet and gas sampling in narrow ducts of a gas turbine or any other device with an oil breather
First Claim
1. An analysing arrangement for analysing a composition of a fluid of a gas turbine, the analysing arrangement comprising:
- a breather pipe configured to be coupled to the gas turbine such that at least a part of the fluid is flowing through the breather pipe,a first collecting device for collecting a first sample of the fluid, wherein the first collecting device is configured for providing a first composition analysis of the first sample, anda second collecting device for collecting a second sample of the fluid, wherein the second collecting device is configured for providing a second composition analysis of the second sample,wherein the first collecting device and the second collecting device are arranged inside the breather pipe such that the first collecting device and the second collecting device are exposed to a common flow characteristic of the fluid inside the breather pipe; and
wherein the first collecting device and the second collecting device are offset with respect to each other around a centre axis of the breather pipe and have a common distance (d) to a pipe wall of the breather pipe.

Abstract
An analyzing arrangement for analyzing a composition of a fluid, such as oil mist of an engine, e.g. a gas turbine is provided. The analyzing arrangement includes a breather pipe coupleable to the gas turbine such that at least a part of the fluid is flowing through the breather pipe, a first collecting device for collecting a first sample of the fluid, wherein the first collecting device is configured for providing a first composition analysis of the first sample and a second collecting device for collecting a second sample of the fluid, wherein the second collecting device is configured for providing a second composition analysis of the second sample. The first collecting device and the second collecting device are arranged inside the breather pipe such that the first collecting device and the second collecting device are exposed to a common flow characteristic of the fluid inside the breather pipe.
