Abstract (en)

[origin: FR2809808A1] The magnetic position sensor has two ferromagnetic assemblies (40,40') with a principal air gap (44) between them. A permanent magnet (41) attached to the subject being measured moves in the air gap. Each ferromagnetic assembly is divided into two parts (42,42'43,43') and magneto-sensitive elements (46,46') are located in the secondary air gaps (45,45').
