Pressure Sensors for Aerodynamic Testing and Analysis

132B38 Microsensor

Micro ICP® Pressure Sensor


Model 132B38

For measurement of short wavelength pressure pulses, 132B38 piezoelectric ICP® micro pressure sensor features 0.5 microsecond response. The sensor's micro-second response time accurately measures pressure peaks from fast rising shock waves and very high frequency pressure phenomena. The 1mm diameter sensing element allows measurement of short wavelength incident pressure waves. A short time constant filters off the static component of wind tunnel pressure, allowing differentiation of consecutive pulses. Key application includes measurement of boundary layer transition.

  • Measurement Range: 50 psi (345 kPa)
  • Sensitivity: (±30%) 140 mV/psi (20.3 mV/kPa)
  • Resolution: 0.001 psi (0.007 kPa)
  • Low Frequency Response: (-5%) 11 kHz
  • Weight: 12.77 gm

Model 831 Sound Level Meter

Miniature High Sensitivity ICP® Probes


Models 112A22 & 112M362

Used to measure small dynamic pressures such as turbulence, noise, sound, cavitation and pulsations, especially in adverse environments. Capable of measuring high intensity sound pressures from 0.001 psi to 50 psi (111 to 205 dB in air). Internal acceleration compensation minimizes vibration sensitivity and an internal discharging resistor automatically eliminates static (DC) signal components.

  • Measurement Range: 50 psi (345 kPa)
  • Sensitivity: (±15%) 100 mV/psi (14.5 mV/kPa)
  • Resolution: 0.001 psi (0.007 kPa)
  • Low Frequency Response: (-5%) 0.50 Hz
  • Resonant Frequency: ≥250 kHz
