| 摘 要： | 提出了一种检测单一油罐中油水双液位的新方法,设计了一种新结构的传感器。这种液位传感器能通过检测电感和电容来评价油液位和油水界面的高度。为了实现多传感功能,传感器由2个线圈同时紧密缠绕在相同塑料管外壁设计而成。根据油水界面的液位与2个线圈连在一起所得到单一线圈的电感、油液位与2个线圈间电容的相互关系,油水界面液位和油液位能被同时估算出来。

| Abstract: | A novel approach for oil-water interface level and oil level monitoring in a single tank is presented.This liquid level sensor can determine the height of oil-water interface level and oil level.For achieving multi-sensing function,the designed sensor employs two coils wound on a plastic pipe.According to the relationships between oil-water interface level and inductance produced by a coil connected using the two coils,oil level and capacitance measured from two coils,the oil-water interface level and the oil level can be estimated at the same time. |
