This paper presents a Fabry-Perot sensor-based measuring system that is used for measuring fluid composition in demanding industrial applications. The sensor design incorporates a two-parametric sensor, allowing for simultaneous measurement of temperature and refractive index (RI). The system has undergone testing under real industrial conditions, and has been proven effective for temperature-compensated online measurement of emulsion concentration with a high resolution of 0.03 Brix. The measuring system includes emulsion filtering and automatic sensor cleaning, which are crucial for successful implementation of a fiber optic RI sensor in emulsion monitoring applications.
This paper describes a Fabry-Perot sensor-based measuring system for measuring fluid composition in demanding industrial applications. The design of the sensor is based on a two-parametric sensor, which enables the simultaneous measurement of temperature and refractive index (RI). The system was tested under real industrial conditions, and enables temperature-compensated online measurement of emulsion concentration with a high resolution of 0.03 Brix. The measuring system was equipped with filtering of the emulsion and automatic cleaning of the sensor, which proved to be essential for successful implementation of a fiber optic RI sensor in machining emulsion monitoring applications.
