The FRI is a miniature sensor that provides in-situ refractive index measurements and allows continuous monitoring of any process, whether industrial, chemical of food-engineering, thus eliminating manual sampling and measurements repeat-
ability problems. These sensors are also designed to withstand variable tempera-
ture, EMI and vibration conditions.Research engineers working in cooling systems development, those involved in any area where fl uids chemistry and fl uids quality control are applied, may now improve process and product technology by monitoring the performance of specifi c properties over time. This will provide accurate information on changes in the refractive index during the operation, the manufacturing process or throughout the lifetime of a product. The use of the FRI refractive index sensor allows a complete refractive index analysis in the most challenging environments.Our unique design is based on the variation of a liquid-fi lled Fabry-Perot optical cavity length to precisely determine the refractive index of the liquid. The liquid-
fi lled optical cavity length varies in direct proportion with the refractive index of the liquid sample. The refractive index measurement is achieved by measuring the Fabry-Perot cavity length using white light interferometer technology.The fi ber optic signal conditioner has the capability to perform the refractive index measurement under challenging conditions of temperature, EMI, humidity and vibration with uncomplicated calibration tasks that the user can perform.The FRI fi ber optic refractive index sensor provides the industry with better and more reliable refractive index measurements for existing applications, and with extended capabilities for new applications requiring continuous in-situ monitor-
ing of fl uids refractive index under adverse conditions.The FRI fi ber optic refractive index sensors are available in a miniature package (FRI-BA model) or in a rugged stainless steel package (FRI-NP model), suitable for industrial applications.
