The architecture uses several sensors that measure same quantity and each is fed to Kalman filter.

Based on the values of the correlation coefficient an adjustment to the measurement noise covariance matrix (R) was made using fuzzy logic technique. Predicted outputs obtained from Kalman filters were fused together based on weighting coefficient, which was also obtained from the correlation coefficient.

The considered signal is a pulse with a rapid first transition, followed by a nearly constant region followed by a second transition that is much slower than the first. The advantage of such a signal is that, unlike a symmetric pulse, its Fourier transform has no zeros. This allows one to divide by the Fourier transform in the data analysis. It is shown that such a pulse retains the advantages of using an impulse-like or step-like stimulus. Error estimates similar to those previously published for impulse-like and step-like stimuli are given for the asymmetric stimulus","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123827105","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}

Like lifetime measurements, ratiometric techniques are insensitive to the variations of the excitation light, optical path and photo-bleaching. In this work, we present a ratiometric method based on the phosphorescence-fluorescence spectral overlap emission of a phosphorescent chemical sensor. This dual emission makes ratiometric measurements possible without need of adding a reference luminophore. The ratio is calculated by measuring the phase shift between the excitation and the emission signal at two different frequencies. Theoretical aspects of the proposed methodology and the design and construction of a fiber-optical measuring system are discussed. Finally, the performance of the proposed measurement method has been assessed using the metal chelate Al-Ferron immobilized in an inorganic sol-gel support (an oxygen indicator which displays a strong fluorescence emission overlapping significantly with the measured phosphorescence emission)","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124214806","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}

At constant temperature, ultrasonic density sensors can reach accuracies of 0.1%. However, temperature fluctuations are expected to exist in an industrial plant, and sensor performance must be studied in the presence of temperature gradients. Each sensor geometry and construction can give rise to different behaviors under temperature gradients, limiting the possible accuracy in density measurements. In this work, an ultrasonic density measurement cell is experimentally characterized and its performance in the presence of temperature gradients is studied in the 15 to 40degC temperature range for several liquids. The propagation velocity can be measured with high accuracy (0.07 %) in a range of temperatures as long as the sample chamber length is corrected. The cell was tested with distilled water, alcohol and other liquids, showing 0.2 % accuracy in density measurement for stabilized temperature and 0.4 % under thermal gradient conditions","PeriodicalId":244878,"journal":{"name":"2005 IEEE Instrumentationand Measurement Technology Conference Proceedings","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116468998","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}
