Abstract

Telah dilakukan penelitian tentang perancangan sistem sensor temperatur tinggi berbasis fiber bragg grating (FBG) dengan metode enkapsulasi. Metode Enkapsulasi FBG menggunakan ceramic tube berbahan dasar mullite ceramic dan Geopolymer Ceramic. Penelitian ini menggunakan efek pergeseran panjang gelombang Bragg (λB) akibat pengaruh perubahan temperatur pada FBG. Akuisisi data pergeseran panjang gelombang Bragg (λB) menggunakan Optical spektum analyzer(OSA) dengan sumber cahaya dari Internal Wavelength Calibrator. Hasil pengujian karakteristik sensor diperoleh nilai sensitifitas Bare FBG sebesar 10 pm/oC sedangkan pada sistem sensor Keramik Mullite dan sistem sensor keramik geopolimer memiliki sensitifitas masing-masing sebesar 11 pm/oC dan 6 pm/oC. Resolusi untuk Bare FBG diperoleh 0.1oC sedangkan pada sistem sensor Keramik Mullite dan sistem sensor keramik geopolimer diperoleh resolusi masing-masing sebesar 0.08oC dan 0.15oC. Metode enkapsulasi telah berhasil meningkatkan Range pengukuran FBG dari 300oC menjadi 386oC dengan keakurasian, presisi dan kestabilan yang tinggi. ========== It has done a research about system design of high-temperature sensor that based on fiber Bragg grating (FBG) with encapsulation method. The FBG encapsulation method uses a ceramic tube which contains mullite ceramic and Geopolymer Ceramic. This study uses Bragg wavelength shift effect (λB) as a consequence of the effect of temperature changes on the FBG. Data acquisition of Bragg wavelength shift (λB) uses Optical spectrum of analyzer (OSA) with a light source from the Internal Wavelength Calibrator. The test results of sensor characteristics are obtained sensitivity value of Bare FBG at 10 pm /0C, while the Mullite Ceramics sensor systems and geopolymer ceramic sensor systems have a sensitivity respectively at 11 pm /0C and 6 pm /0C. Resolution for Bare FBG is obtained 0.1 0C, while the Mullite Ceramics sensor systems and geopolymer ceramic sensor systems are obtained resolution respectively at 0.08 0C and 0.15 0C. Encapsulation method has been successful to increase FBG measurement range from 300 0C to 386 0C with the accuracy, precision and high stability.
