Giant Magneto-Resistive (GMR) Sensors for Non-Destructive Detection of Magnetic Flux Leakage from Sub-Surface Defects in Steel

There is an increasing demand for using high sensitive sensors which can detect very low levels of magnetic flux leakage from hidden defects or far-side wall loss due to pitting or local corrosion in ferromagnetic steels. This paper discusses the use of highly sensitive tiny GMR sensors for detection of sub-surface defects in carbon steel plates. Notches located at different depths below surfac...

Design and characterization of a linear position transducer based on Giant Magneto Resistance (GMR) effect

In this report we describe a new linear position transducer based on the giant magneto resistance (GMR) effect. The GMR effect is a phenomenon observed in multilayer structures consisting of ferromagnetic, antiferromagnetic and paramagnetic metal films. The transducer consists of four GMR elements configured in a Wheatstone bridge with 380 Ohms nominal resistance of each leg. GMR elements were ...

Bi-Directional Giant Magneto Impedance Sensor

A thin film giant magneto impedance (GMI) based on magnetic field sensor has been developed using electrodeposited Ni-Fe permalloy. Chemical composition, surface morphology, and magnetic properties of Ni-Fe permalloy were characterized as a function of plateup parameters, and process conditions were established to deposit a Ni-Fe thin film with a high permeability (~1000) and a low coercivity (...

Eddy-current Testing with Gmr Magnetic Sensor Arrays

The advent of GMR magnetic sensors and GMR sensor arrays with frequencyindependent sensitivity offers improvements in speed, depth, and resolution in eddy-current testing. Arrays of GMR magnetic sensors allow rapid scanning of an area for defects in a single pass. The small size and low power consumption of these solid-state magnetic sensors enable the fabrication of compact arrays of sensors o...
