Magneto-inductive sensor array for determining position and/or travel - has magnets which move over and saturate magnetic panel, provided with pairs of coils forming transmitter/receiver systems, voltages induced in coils being measured

摘要: The array (row) of sensors determines the position or travel permanent magnets (8) electromagnets adjacent to sensors, with a flat magnetic panel (1) which can be caused saturate by (2,3,4,5,6,7) arranged next above one another. coil turns (2',2",3',3",4',4",5',5",6',6",7',7") lie another in configuration at least plane and move coils along panel. At two form transmitter/receiver system an a.c. voltage pulses are impressed on transmitter they induce receiver is measured.
