The principle, performance and test results of a new on-line iron spectrometer are introduced. The DSP calculates the percentage of shading area, the wear index and the classification features of large abrasive particles to determine the worn state of the monitored machine and predict the abnormal wear. It shows that the developed instrument can meet the requirement of on-line wear detection well
