Through the design and analysis of
capacitive crude oil water content sensor, the development of sensor signal drive and conditioning circuit,
water content error compensation and data processing algorithm research,
a new full range water content tester was trial-produced. Its innovative points
are: using the finite element analysis method to establish a sensor
electromagnetic field simulation model, analyze the sensor’s electric and magnetic
field parameters, change the sensor’s size and structure and achieve
performance optimization; establish a noise transfer model of capacitor sensing
circuit, analyze various noise sources, and adopt error suppression techniques
to improve the signal-to-noise ratio of the
circuit and optimize the circuit performance; study the high-precision
calibration algorithm of crude oil water content data, and embed the
calibration algorithm into the single-chip system to achieve remote real-time
calibration according to the needs of on-site monitoring.</span><span style=\"font-size:14px;\"></span>
