PROBE FOR MEASURING PRESSURE OSCILLATIONS IN COMBUSTOR OF GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a redundant probe that captures the full frequency range of importance without significant signal distortion and damping.SOLUTION: A stepped bore 102 receives a sensor plate 110 that holds at least two or more pressure transmitters 2, and a face 118 of the sensor plate 110 and a shoulder 106 define a cavity 120, thereby connecting a measuring bore 104 with sensing surfaces or diaphragms 122 of at least two pressure transmitters 2.
