  • Inductive displacement sensor with a measuring head comprising a passive resonant circuit
    Patent number: 6943543
    Abstract: An inductive displacement sensor having a displaceable or rotatable, magnetically permeable measuring head, at least one measuring loop whose geometric shape varies in response to the longitudinal/rotary displacement of the measuring head, and at least one excitation loop by which a magnetic flux can be generated in the measuring head. The flux penetrates the at least one measuring loop at any point of the longitudinal/rotary displacement, essentially in the region of the measuring head, and inducing an electric measuring signal (i2). A resonant circuit, which is electrically decoupled from the outside, is arranged on the measuring head and is excited in correct phase relation by a short voltage pulse after a number of, preferably, 10 to 20 free oscillations.
