| 摘要: |
| 采用电容式传感器研究了测量水流泥沙含量的自校准技术。结果表明，水流泥沙含量与传感器的输出呈线性，可采用实时标定的自校零与自校准技术，将传感器与微型计算机结合起来，在智能化软件的引导下，可自动校正因零漂移，灵敏度漂移而引入的系统误差和可变误差。 |

| Research on the capacitance sensor self-correcting technique for measuring sediment concentration in the flow-water |

| Abstract: |
| By adapting the capacitance sensor,a self-correcting technique for measuring sediment concentration in the flow-water has been studied.The experimental results showed that the sediment concentration in the flow of water is in line with output of capacitance sensor.Using the zeroing & self-correcting technique standardization,and combining the capacitance sensor with micro-computer under the software leading,it can be self-corrected the systematic errors & indeterminate errors produced from the drift of zeroing & sensitivity. |
| Key words: capacitance sensor sediment concentration zeroing self-correcting |
