| Abstract: |
| AC-coupling method was applied in real-time concentration inspection of sand and dust in sand and dust test equipment. The composition and framework of closed loop control system were introduced. The characteristics and theory of AC-coupling method were analyzed and studied. Factors affecting the measurement effects were also put forward. Combining the closed loop control system of concentration measurement of sand and dust in the equipment, the specific operation flow and methods were introduced. The control effect of the control system was validated with practical application. It was proved that the control system has good control effect and achieves the expected goal. |
