Abstract

The optical fiber sensing system is free from the effects of electromagnetic wave interference and radio frequency interference. It becomes a strong reason why this research takes the topic of temperature sensor design using fiber optics. The temperature difference between the incoming light source at one end of the fiber optic cable and the temperature of the sensor will cause a difference in wavelength between the incoming light source and the light reflected by a sensor or passed by a sensor. The difference in wavelength will be converted into RGB value, then it will be converted into a temperature. The method of designing fiber optic sensors used in this research is experiment, called: - heating the ends of the fiber optic core with analytic splicers so they will obtain the shape of the optical fiber end such as spherical and oval fiber optic ends, -peeling the jacket between two ends of the fiber optics and coating optical fiber with plates. The test results for temperature measurements between 303oK to 545oK show that (1) reflected (a) spherical optical fiber sensor has a 7% error, (b) oval optical fiber sensor has a 7.5% error, and (2) forwarded, has an error 1.296 %.
