Abstract

The employment of sensors in harsh environments [1] is a challenging engineering task, occurring more frequently than it might be expected. So, the availability of reliable and accurate sensors is a task in great demand. However, this imply an effort demanding and an expensive design. In this frame we can place the present contribution which aims to develop a simple, robust magnetic filed sensor to be exploited in harsh conditions, such as the the Tokamak vessel for nuclear fusion experiments [2] where the presence of standard sensors based on electronic circuits based and hall effect is almost impossible.
