摘要：For the present, the concentration of ceramic slurry is measured using the traditional physical method. The measuring accuracy of this method is not high and the efficiency is low. In order to measure the concentration of ceramic slurry quickly and easily, a new type of detection equipment need to be developed. Based on Mie scattering theory, the integral formula of total reflecting light intensity is deduced. It proves that to using scattering methods to measure the concentration of ceramic slurry is feasible. In the experiment, an optical fiber of double-D Optical Fiber Sensor made the 650nm wavelength red laser light directly enter the ceramic slurry. Another optical fiber received the scattering laser light coming from the ceramic particles, and absorbed the light into the photosensitive element. By processing the signal of the Optical Fiber Sensor using the circuit designed, the Voltage value can be obtained. By measuring some ceramic slurry samples separately whose clay content varied from 0 percent to 60 percents, a set of data is got. After this set of data being analyzed it can be known that the data curve is nonlinear when ceramic slurry content is from 0 percent to 60 percents. It is linear when the content of ceramic slurry is from 55 percents to 60 percents. Based on the results of this experiment, a ceramic slurry concentration detection device was developed. ©2010 IEEE.
