abstract

An innovative temperature sensor has been presented based on “Faraday Effect”. The Faraday Effect or the Faraday rotation is a magneto-optical phenomenon; that is, an interaction between electromagnetic wave and a magnetic field in a medium. Optical sensors based on the Faraday Effect have the advantages of simplicity, high electrical insulation and immunity to electromagnetic interference. We will be making use of an optical fiber and a permanent magnet as our sensing elements. The magnet will be the sensing element for change in temperature and the fiber optic cable will sense the change in magnetic field intensity corresponding to the change in temperature.
