摘要
推导出浮子电容式石油密度传感器的数学模型，设计了机械、电路结构，进行了误差分析和误差修正．根据阿基米德浮力原理，采用不锈钢浮子及多层筒形电容，组成高精度石油密度传感器．
On the basis of Archimedes buoyancy principle,a new petroleum density sensor with capacitance transducer,elastic plate and buoyancy force is instroduced in this paper.The authors analyzed the principle of the sensor and designed the circuits and machine structure of the sensor,By means of error correction,the accuracy of the sensor has been improved.
