Abstract: 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.Keywords: optical fiber sensors, Fabry–Pérot interferometer, refractive index, temperature, emulsion concentrationPublished in DKUM: 06.02.2024; Views: 336; Downloads: 27 Full text (4,44 MB)This document has many files!
