Design, experimentation, and simulation of dynamic pressure sensor inserts: towards reducing oscillations in measurements
Design, experimentation, and simulation of dynamic pressure sensor inserts: towards reducing oscillations in measurements
Dynamic pressure measurements are crucial for accurately monitoring and optimizing the performance of high-speed screw compressor systems. However, high sensor sensitivity combined with dynamic pressure effects can lead to nonphysical oscillations, distorting test results and compromising data reliability. This study addresses these challenges by using a lumped parameter model to analyse the pressure oscillations, identifying key factors that influence the system’s response. Experimental validation demonstrates that the optimized sensor insert design significantly reduces oscillations, thereby improving the stability of pressure measurements and mitigating nonphysical signal distortions. An additional comparative analysis is conducted between experimental results and analytical lumped model derived from sensor inserts. This integrated approach provides a comprehensive framework to improve the dynamic pressure assessment in high-speed screw compressors.

Abstract
Dynamic pressure measurements are crucial for accurately monitoring and optimizing the performance of high-speed screw compressor systems. However, high sensor sensitivity combined with dynamic pressure effects can lead to nonphysical oscillations, distorting test results and compromising data reliability. This study addresses these challenges by using a lumped parameter model to analyse the pressure oscillations, identifying key factors that influence the system’s response. Experimental validation demonstrates that the optimized sensor insert design significantly reduces oscillations, thereby improving the stability of pressure measurements and mitigating nonphysical signal distortions. An additional comparative analysis is conducted between experimental results and analytical lumped model derived from sensor inserts. This integrated approach provides a comprehensive framework to improve the dynamic pressure assessment in high-speed screw compressors.
