DEVICE FOR CORRECTION OF THE INTERFERENCE ERRORS

摘要

The invention relates to a device for the correction of interference errors in a measuring unit (A), comprising: at least two magnetic sensors (11, 12), for measuring the position of moving objects (21, 22) which move following adjacent displacement trajectories, each magnetic measuring sensor providing a measuring signal representative of the position of the moving object in an open magnetic circuit (31, 32) and processing means (M), for measured signals provided by the magnetic measuring sensors. According to the invention, the processing means (M) comprise means for correction of the measured magnetic signals to take into account interference errors between adjacent magnetic sensors (11, 12) in order to obtain a corrected measured signal for each measuring magnetic sensor.
