High-Temperature, Fiber-Optic-Readout Pressure Transducers

摘要

Fiber-optic-coupled differential-pressure transducers are being developed for use in hot, harsh environments like those in the cores of aircraft turbine engines. The prior approach to the measurement of pressures in such engines involves the use of pressure transducers coupled to pressure taps via long tubes, which introduce delays and degrade responses to high-frequency pressure variations.
