Calibration method and system for a dynamic combustor sensor

摘要

A pressure sensor calibration system (10) comprises a pressure chamber (32) in fluid communication with a pressure sensor (12) to be calibrated, the chamber being pressurized to a static pressure level. An oscillating surface (36) on a wall of the chamber imparts a rapid pressure fluctuation in the static pressure level of the chamber. These rapid pressure fluctuations in a high-static pressure level chamber are used to calibrate the pressure sensor.
