摘要
提出了采用单个传感器实现同一成品油储罐中油温、油位的监测新方法。该方法可以实现电阻和电容传感功能。为了实现油罐中油温、油位的同时检测,所设计的传感器使用了绕在塑料管上的两个线圈作为敏感元件。电阻由两个线圈组合连接成一个线圈后测得,电容在两个线圈间测得,根据油温和电阻之间、油位和电容之间的函数关系,便可以同时计算出油温、油位值。实验结果证实了新方法的可行性及实用价值。
A novel approach for monitoring oil-temperature and oil-level in a single tank is presented.A multifunctional sensor that is suitable to determine the oil-temperature and oil-level has been developed.This proposal can realize two sensing functions of resistance and capacitance.To achieve this multi-sensing function,the designed sensor employes two coils wound on a plastic pipe.According to the relationships between oil-temperature and resistance produced by a coil connected using the two coils,oil-leveland capacitance measured from two coils,the oil-temperature and oil-level can be estimated at same time.Experimental result shows good application and development prospect of the new method.
