Measuring Displacement
Basic concepts
Because of their high sensitivity, GMR Magnetic Field Sensors can effectively provide positional
information of actuating components in machinery, proximity detectors, and linear position
transducers. The figures below illustrate two simple sensor/permanent magnet configurations used to
measure linear displacement. In the first diagram, displacement along the y-axis varies the Bx field
magnitude detected by the sensor that has its sensitive plane lying along the x-axis. The second
diagram has the direction of displacement and the sensitive plane along the x-axis.
Application examples
• Hydraulic/pneumatic pressure cylinder stroke position
• Suspension position
• Fluid level
• Machine tool slide position
• Aircraft control-surface position
• Vehicle detection
