  • Page 19: Measuring Principle

    PT3E-0220 11. MEASURING PRINCIPLE The refractive index of a mixture gas is determined by the kinds of composing gases and the mixture ratio. As long as the kinds of composing gases are known, the mixture ratio (concentration) is determined by measuring the refractive index. The optical interferometer applied for the FI-21-SF6 displays “Interference Stripes”, which moves proportional to the refractive index, on the CCD.
