Abstract

Aiming at the existing density detection technologies, this paper proposes and designs a liquid refractive index (RI) sensor based on an all-fiber online Fabry-Perot interference cavity (FPI). We designed a real-time monitoring system by LabVIEW and performed density calibration, bubble and impurity interference and stability tests. The experimental results show that the effective cavity length of the FP cavity and the density have a good linear relationship, the fitting coefficient of the curve is as high as 0.998. Excluding the influence factors such as impurity，air bubbles and high temperature, the maximum offset between the measured value after temperature compensation of liquid density and the real value is within ±0.0024g/cm³.
