Studies on optical-fiber sensor to monitor temperature using reversible thermochromic gel type cobalt(Ⅱ) chloride/polyvinyl butyral |
| 초록 |
In this study, we developed an optical-fiber sensor using cobalt chloride solution to monitor temperature in real-time between long distance points unaffected by the electro-magnetic wave and the vibration. Cobalt chloride solutions were made using 10 % water and 90 % ethanol (v/v) solution. The transmittance of these solutions were analyzed on 655 nm using UV-Visible spectrometer regarding temperature change. Also these solutions were gelled by dissolving polyvinyl butyral and the transmittance of them were analyzed on 655 nm regarding temperature change. The results of transmittance and optical power measurement showed decrease of both transmittance and optical power with increase of temperature from 66.8 % and 149.5 nW at 25 ℃ to 7.1% and 48 nW at 70 ℃, respectively. |
