Abstract

A new system of comparative pressure leak-detection with fiber-optic sensors is advanced and studied. The expression for differential pressure, detecting time, and minimum detectable leak rate is derived through the study of the pressure in the detected device applied pressure with relation to the detecting time. The fiber-optic differential pressure sensor with high sensitivity and stability is presented and designed. Minimum value of relative differential pressure detected is approximately 3X10-5. Finally, an example of the system used in industrial production is given.
