Abstract :
As a kind of on-line measurement technology possessing advantages of unperturbed, non-radiant and visualization, Electrical Resistance Tomography has wide application prospect in petroleum and chemical industrial production processes which are based continuous-phase conductive medium. For extracting information of the production processes efficiently, a kind of 16 electrodes ERT system based the industrial CompactPCI Bus and FPGA technology is designed. The new system is tested in laboratory, the speed of the system can reach more than 1300 frame/s at the 100kHz sine wave injecting signal, even faster at higher frequency, the Signal-to-Noise ratio of the system can reach above 73dB, and the tomography speed can reach 60 frames/s with pre-iteration algorithm based on the Landweber method.
