Sensors for aerodynamics & aero-acoustics measurements

Wind tunnels allow aerodynamic engineers to make pressure and force measurements on aircraft or rocket models to improve aerodynamic performance. From subsonic use of condenser microphones for acoustic holography, to shock wave pressure sensors for studying boundary layer transition at high hypersonic Mach numbers, PCB manufactures a sensor for most aerodynamics & aero-acoustics applications.

Piezoelectric Microphones

Measuring high intensity acoustic noise and very low pressure fluctuations in harsh environments, piezoelectric microphones are designed for a wide range of environmental conditions, including insensitivity to altitude changes. Piezoelectric microphones are self-generating devices that require no external power source.

ICP® Acoustic Pressure Sensors

ICP® acoustic pressure sensors can also measure high intensity acoustic noise and very low pressure fluctuations in harsh environments. With ICP acoustic pressure sensors, ICP constant current provides power.

Miniature ICP® Accelerometers

Miniature piezoelectric accelerometers are required for applications demanding high frequency range, small size, and low weight. Available in both single-axis and triaxial configurations, mini ICP accelerometers are used extensively for measuring a flight vehicle or aerodynamic model vibration response during wind tunnel testing.

Miniature ICP® Pressure Sensors

For measurement of short wavelength pressure pulses, micro ICP pressure sensors feature micro-second response time that accurately measure pressure peaks from fast rising shock waves and very high frequency pressure phenomena. Miniature high sensitivity ICP probes are used to measure small dynamic pressures such as turbulence, noise, sound, and pulsations, especially in adverse environments.

Endevco Piezoresistive Pressure Sensors

PCB is well known for our quartz ICP piezoelectric pressure sensors; now we also offer Endevco's piezoresistive pressure sensors. With designs suitable for airflow measurements or high intensity sound, these pressure sensors feature quick response times and high output for excellent signal-to-noise ratio. They measure both static and dynamic pressure.

Force Sensors

PCB force sensors for aerodynamics & aero-acoustics applications feature high stiffness, fast response and repeatable performance, permitting them to capture high frequencies and follow fast transient events such as reaction forces due to turbulence or shock waves.


Aerodynamics & aero-acoustics sensors are used for:

  • Airplanes
  • Airfoil studies
  • Rockets
  • Buffeting
  • Re-entry vehicles
