Abstract

A gap measurement device. The device has a circuit having a variable inductor and a capacitor. The variable inductor has an indicator. The device has a gap that includes a gap measurement and a gap length. The gap measurement is related to the inductance. The gap is configured to receive at least a portion of the variable inductor while the variable inductor moves along the gap length. The movement of the variable inductor along the gap length causes the inductance to change in response to the gap measurement.
