초록

DOT-3 규격의 자동차 브레이크액에 대하여 수분 함유량과 시스템 마찰로 인한 오염도를 전기저항과 광학 투과율을 측정하여 비교하였다. 기존의 저항측정법은 수분 함유량을 주로 측정하는 반면에 광학 투과율 방식은 제동장치 내부의 마찰에 의하여 발생된 입자의 오염을 포함하여 측정할 수 있어서 저항변화 측정보다는 광학 투과율 방법이 더 선형적이고 효율적이었다.

The results of between resistance and optical transparency measurement in DOT-3 brake fluid contaminated moisture and particles generated from fraction of brake system was compared. Conventional resistance measurement method was known to be effaced by it's hygroscopic characteristics. However, the particle is a significant element of the contamination sources. Proposed optical transparency measurement is linear and effective than that of contamination in brake fluid.
