Continuous stress annealing of amorphous ribbons for strain sensing applications

Abstract Stress-annealed amorphous Co 69 Fe 2 Cr 7 Si 8 B 14 ribbons are suitable materials for strain sensors required in civil engineering applications. The equipments for the continuous stress-annealing of ribbons and the automatic homogeneity test of magnetic properties are described. The magnetic properties of stress-annealed ribbons are discussed. The use of ribbon in an inductive strain sensor is also illustrated.
