| Abstract: | A new approach was put forward to auto_correct the dust particle counter. The counter is used to measure the number and size of dust particles in clean air. The incident light is scattered by the dust particle and the scatter intensity is related to the size of the particle. So keeping constant detection sensitivity of the particle counter is the point for precise measurement. An auto_corrector was designed to adjust the sensitivity of BCJ_1 dust particle counter. The intensity of incident light and noise of the system are monitored. The auto_corrector can always retain the same sensitivity as the scaled sensitivity by compensation. |
