However, between 450 and 700 Hz they typically fail to transfer data at as little as 1 g. These data failures can be attributed to two key components: the suspension arm and the hard disk.

The system operates on the two-colour principle combining advanced optical sensing and digital image processing techniques. The temperature of a flame is calculated from the ratio between the grey-levels of corresponding pixels within two images captured at two different wavelengths. The soot concentration of the flame is estimated using the KL factor which is derived from the intermediate information obtained during the temperature measurement. The prototype system has been evaluated on a 0.5 MW/sub th/ coal-fired furnace. Experimental results obtained show that the system is capable of measuring the instantaneous, two-dimensional distributions of the temperature and soot concentration of the flame with a reasonable accuracy.","PeriodicalId":68878,"journal":{"name":"Journal of Measurement Science and Instrumentation","volume":"52 1","pages":"1221-1226 vol.2"},"PeriodicalIF":0.0,"publicationDate":"2001-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86963786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
