LVDT calibration plot - what is the purpose for frequency respone?

  1. Jan 9, 2010 #1
    I am given the plot done during the calibration of LVDT by pulling and pushing the actautor. The actuator was pulled by 1 cm every few second to full extent and then back ( or it was pushed and then pulled, does it matter?).
    What are the meanings of values of the vertical and horizontal axis? Is one of the the displacement of 1 cm? What is the other?
    The goal is to find the frequency response having the sinewaves of the input and output.
    But what do I need the calibration plot for?
    The plot is attached here.
    Thanks anyone for help.
