Design a new type sensor using Hall effect to measure crank deflection
through finite element analysis method to calculate magnetic field distribution of space around cylindrical permanent magnet
study on influence of the two permanent magnets with location of symmetrical arrangement and relative position of Hall element and permanent magnet on micro displacement measurement precision of sensor
the optimal selection scheme are obtained.Experiment shows relationship between output and displacement is linear in the range of 0
2
mm
measurement precision of the system can achieve 0.001 mm
which is suitable for measurement of microdisplacement of crank deflection measurement.
