This article presents a low cost fiber optic pressure sensor using metal diaphragm.The sensor works on the principle of fiber optic proximity sensor. As the pressure varies, the deflection of the diaphragm varies and it modulates the intensity of light reflecting from the diaphragm. The performance of the sensor is studied for different diameters and thicknesses of the diaphragm. © 2012 Wiley Periodicals, Inc.
