Paper Abstract

This paper introduces a new method to detect drilling fluid density based on intelligent sensor, the core of which is silicon resonant sensor technology. Two H model resonant beams locating single crystal silicon resonant sensor con vert differential pressure to frequency signals respectively, then difference of two frequency signals are transmitted to CPU, export 4~20mA signal corresponding drilling fluid density after D/A converter. This method get over the short comings of typical drilling fluid density detection used piezocapacitive sensor, such as low accuracy, shattered easily, easy drift ...ect., has high precision, stability and reliability characters.
