This thesis is about the result of conducting a specific experiment for the development of noncontact vibration displacement sensor for measuring the spindle vibration that is used for conditional monitoring of machinery. One should be careful when using the eddy current type displacement sensor because the sensitivity of it is different according to the quality of the material.
While the probe used for nondestructive inspection adopts the effect of transmitting the material by using the high frequency domain, the eddy current type displacement sensor uses the lower frequency of around 1㎒.
Also, while the nondestructive probe uses the method of enhancing output by using the resonance zone, the vibration displacement sensor utilizes the stable zone by avoiding the resonance zone.
Since the oscillator of the converter uses the “L” element as Probe, its characteristic changes with the variation of a relevant impedance.
In other words, if the length of Probe’s Cable gets extended (Impedance increase), the sensitivity declines accordingly.
The effect of surrounding temperature was small, but the influence of the quality of Sensor Coil used was high.
Moreover, following an experimental demonstration of the phenomenon where the sensitivity decreases as the frequency of the tested material increases from a frequency response test, the maximum frequency that could be measured was approximately 1㎑. It was noted that the degree of precision could be maintained by using the gap of the probe in the linear zone at the installation site.
