In displacement measurement using LVDT
1
Direction of displacement is determined by the difference in the RMS value of the secondary voltage and primary voltage.
2
Direction of displacement is determined by the phase of secondary voltage with respect to the phase of primary voltage.
3
Direction of displacement is determined by the phase difference between the two secondary voltages
4
Direction of displacement is determined by the difference in the RMS value of the two secondary voltages
