Capable of measuring the refractive indices of various liquids, ultra-compact optical fiber refractive index sensor.

This is a super compact optical fiber refractive index sensor capable of measuring the refractive indices of various liquids. It enables in-situ refractive index measurements and long-term monitoring in various processes (such as food processing and chemical plants), eliminating the need for sampling, resolving issues related to repeated measurements, and establishing improved efficiency, safety, and quality control. The conditioner allows for multi-channel measurements (1 to 32 channels) and offers cost advantages and convenience by enabling the simultaneous use of all optical fiber sensors (temperature, displacement, pressure, strain, load, refractive index). - The refractive index measurement is conducted using the white light interference method based on the Fabry-Pérot cavity length. - The length of the FPI cavity filled with liquid changes in direct proportion to the refractive index of the liquid. - The signal conditioner can be used without complex calibration operations and is reset in air for use. - The measured RI value corresponds to the average refractive index in a radius of 800 nm. 【Features】 ● Refractive index range of 1.0000 to 1.7000 ● Explosion-proof ● EMI and RFI resistant ● Resolution of 0.0001 RI *For more details, please inquire through the document request.
