Document Type and Number:
WIPO Patent Application WO/2020/091273
Kind Code:
A1
Abstract:
A photoacoustic device for analyzing a dissolved gas in oil comprises: a photoacoustic cell into which a gas to be measured is injected, the photoacoustic cell being connected to an infrared ray inflow part through which an infrared ray emitted to the gas to be measured passes, wherein an optical sound caused by reaction between the gas to be measured and the infrared ray is generated in the photoacoustic cell; an optical filter part which is rotatably installed over the photoacoustic cell and through which the light of the infrared ray passes; a driving part for providing a rotation driving force to the optical filter; and a microphone for converting the optical sound generated in the photoacoustic cell into an electric signal.
