Pressure Instrumentation for Gas Turbine Engines—A Review of Measurement Technology

Abstract
Many types and designs of pressure measuring instrumentation are used during the development and testing of gas turbine engines. This paper provides an overview of more commonly available pressure transducers and their characteristics. Probe designs for use in both steady-state and dynamic pressure measurement systems are reviewed. Techniques used to qualify instrument probes and the methods used to calibrate pressure transducers during engine testing are described.
