Abstract

Mineral oil can emit fluorescent when it is initiated by ultraviolet (UV) rays. The mineral oil concentration determination device is designed based on fiber transducer technology and fluorescence analyzing technology. It adopts a pulsed-xenon lamp as an excitation light source, uses a sphere fiber-optics probe to detect fluorescence, implemented optoelectronic conversion of the fluorescence signal and the high speed data acquisition with high-sensitivity array charge-coupled devices(CCD), designes corresponding weak signal process circuits and applies a computer to store and display the signal collected by the CCD. The system realizes the detection of fluorescence character of mineral oil. Experiment indicates that the system has good linear relationship in the range of 0.0-5.1mg/L for the density of mineral oil and a minimum detecting limit of the density is 0.18mg/L. The linear correlation coefficient r is 0.9981 when an excitation wavelength is 330nm and an emission wavelength is 512nm. It can realize the detection of fluorescence of mineral oil effectively.
