Patent ID: 7288932

Claim:
A device to correct interference errors in a measuring installation (A), comprising: at least two magnetic sensors ( 1 1 , 1 2 ) for measuring the position of mobile elements ( 2 1 , 2 2 ) that are moving along adjacent trajectories, where each magnetic measuring sensor (S 1 , S 2 ) delivers a measurement signal that is representative of the position of the mobile element in an open magnetic circuit ( 3 1 , 3 2 ), and resources (M) for processing the measurement signals delivered by the magnetic measuring sensors, wherein the processing resources (M) include resources for correction of the magnetic measurement signals in order to take account of interference errors between the adjacent magnetic sensors ( 1 1 , 1 2 ) with a view to obtaining a corrected measurement signal (S 1c , S 2c ) for each magnetic measuring sensor.
