Abstract

This paper discuss the theoretical analysis and experimental results of pressure measurement using optical fiber sensor with cladding modification and coating with ZnO (Zinc Oxide as sensitive material to enhanced the performance of sensor that's uses as sensing probe inside the pressure chamber. The modification fiber was coated by dip coating deposition method. During measurement of fiber sensor, the refractive index changes based on different pressure given. The changing of refractive index affects the phase different of optical path along optical fiber. Extrinsic Fabry-Perot Interferometer (EFPI) method is used to obtain the data measurement. Pressure variables prearranged from 0 to 104.8 mBar. The experiment outputs are intensity of reflection light and variety of pressure. The sensitivity of sensor obtained is 1.1% with swelling thickness from 0 to 1.181 im.
