Abstract

The measurement device of internal pressures of small components sealed hermetically was developed. The internal pressure of a sample measured with this device was 43.151 kPa, and the expanded uncertainty ($\kappa$=2) was 741 Pa. The resultant measurement ability of internal pressures in small vacuum components, which had been almost impossible previously, shows the possibility of internal vacuum detection of hermetically sealed parts.

밀폐된 소형부품의 내부압력을 측정하는 장치를 개발하였다. 개발된 장치에서 실험한 시료의 내부압력은 43.151 kPa이었고 국제표준화기구에서 권장한 방법에 따라 계산된 확장불확도는 741 Pa이었다. 본 연구결과로 지금까지는 전혀 측정이 불가능 했던 밀폐된 시료의 내부압력을 측정할 수 있게 되었다.
