ABSTRACT:
An improved electromagnetic scanner has a substantially E-shaped core having an outer surface that is positioned, at a predetermined air-gap spacing, from a regularly grooved ferromagnetic surface of a textile machine. A pair of coils extend around the crosspiece of the core between the outer arms of the core and the middle arm thereof, such coils being connected in series and connected to a bridge circuit to generate an electrical indication that varies at the rate of movement of the grooved ferromagnetic surface past the core in a direction crossing the grooves in the surface. The plane of said core is oblique to the grooves. A pair of abrasion-resistant, non-magnetic contact elements supported in the spaces between the arms of the core, projecting outwardly into the air gap, and are urged into contact with the moving ferromagnetic surface by a spring carried in a housing in which the core and coils are mounted.
