Description
Areas of application
- Measurement of stationary pressures: High accuracy in determining all steady-state pressures on test benches.
- Measurement of non-stationary pressures: Monitoring of dynamic processes in turbomachinery.
- Stall detection: Detection of non-stationary pressure fluctuations to detect flow instabilities.
Functionality and advantages
- Stationary pressure transducers: Esterline 9816 high-precision differential pressure transducers offer flexibility thanks to interchangeable modules and in-house calibration for maximum accuracy.
- Non-stationary pressure transducers: Kulite sensors with high temporal resolution enable precise measurement of blade profile pressures and flow fields.
- Integration: Sensors are integrated into the blading without influencing the airflow around the profile.
Technical details
- Stationary pressure transducers: Modular design for flexible adaptation to different test benches.
- Miniature non-stationary sensors: Compact design and high measuring accuracy for dynamic flow analyses.
- Sensor integration: Precise positioning of the sensors by internal sensor workshop.
