The invention relates to a float process shift window interface analyzer based on continuous
capacitance measurement, comprising shift window-type sensors which are sequentially connected serially, are used for converting the
physical information of an interface to be measured into
electronic information and comprise a plurality of sections of rapiers, a
cantilever-type
bridge circuit, an amplification detection integral circuit which amplifies and rectifies an input
signal to be measured into an integral
signal which is in linear corresponding relationship, a central
processing circuit whichis used for controlling the on and the off of a shift window-type sensor window body and a man-
machine interface circuit which is used for outputting a final
processing result; and according to the float process shift window interface analyzer based on continuous
capacitance measurement, an electric structure is novel and simple, a substance
interface analysis circuit which has high reliability and high precision and does not need manual debugging is arranged, the circuit works reliably and has high efficiency, and the result analysis precision is high. The float process shift window interface analyzer based on continuous
capacitance measurement can be widely applied in the measurement of a gas-
liquid interface, a gas-
solid interface and a liquid-
liquid interface.
