The sensor of ray is not only used for detecting ray but also used for composing the other sensor. It can detect many non-electric signal, the premise should translate the non-electric signal into the light signal. The sensor of ray is a sort of most output and application being most extensive, it is very important in the field of automatic control and none-electric test art.展开更多

The more undissolved solid exists in the mixture of solute and solvent, the less transmitted laser intensity is detected. Only when the transmitted laser intensity in stirring state and that in static state comes into equalization, the dissolving process stops. Under the help of laser intensity judgement, measurements turn to be more feasible and objective, especially at high pressure. The average relative errors for the solubility data determined in this paper are 2.3% for those in the minor value scope and 1.7% for those in the high value scope respectively. Comparison of the experimental solubility data with the literature ones demonstrates that the laser-aid solubility determination apparatus is stable and reliable.展开更多
