SONG Yong-dong, BAI Ze-sheng. Design of crude oil moisture content detection circuit based on CAV424[J]. 2008, (6): 83-84+90. DOI: 10.13873/j.1000-97872008.06.019.
Capacitance method is regarded as the detection methods of the moisture content in crude oil
its conditioning circuits are difficult to achieve high-precision measurement due to the impait of parasitic capacitance and the environmental changes.A detection circuit of crude oil moisture based on the capacitive sensor CAV424 is proposed.Test shows that the difference in value between using this method and distilled water method is less than 5%
