VORRICHTUNG UND VERFAHREN ZUR ANALYSE VON FLUIDEN

WO 200227302 A UPAB: 20050805 NOVELTY - In a process to analyze petrochemical fuel and lubricants, a fiber optic conductor is positioned between a light source and a sensor. The optical conductor is at least partly in contact with the liquid. Rays emitted from the light source are transported through the optical conductor and are detected by a light sensor. DETAILED DESCRIPTION - The optical conductor is an ATR fiber optic wave guide with a polyurethane matrix cavity or cavity coating. In the coating material the -OH components are exchanged for NH2. An amplitude modulator is located between the light source and optical conductor. The amplitude modulator is a paddle wheel chopper or Bragg-grid. A collimator is located between the light source and optical conductor. An INDEPENDENT CLAIM is also included for an analyzer for the above process. USE - For testing the conditions of petrochemical fuel and oils on a prophylactic basis. ADVANTAGE - The low-cost test obviates the need to change engine oil at regular intervals as a precaution without prior test.
