Sensores para medições aerodinâmicas e aero-acústicas

Os túneis de vento permitem aos engenheiros aerodinâmicos efetuar medições de pressão e força em modelos de aviões ou foguetões para melhorar o desempenho aerodinâmico. Desde a utilização subsónica de microfones de condensador para holografia acústica até sensores de pressão de ondas de choque para estudar a transição da camada limite em números Mach hipersónicos elevados, a PCB fabrica um sensor para a maioria das aplicações de aerodinâmica e aeroacústica.

Microfones piezoeléctricos

Medindo ruídos acústicos de alta intensidade e flutuações de pressão muito baixas em ambientes agressivos, os microfones piezoeléctricos são concebidos para uma vasta gama de condições ambientais, incluindo a insensibilidade a alterações de altitude. Os microfones piezoeléctricos são dispositivos auto-geradores que não necessitam de uma fonte de alimentação externa.

Sensores de pressão acústica ICP

Os sensores de pressão acústica ICP® também podem medir ruídos acústicos de alta intensidade e flutuações de pressão muito baixas em ambientes agressivos. Com os sensores de pressão acústica ICP, a corrente constante ICP fornece energia.

Acelerómetros ICP® miniatura

Os acelerómetros piezoeléctricos miniatura são necessários para aplicações que exigem uma gama de frequências elevada, dimensões reduzidas e baixo peso. Disponíveis em configurações de eixo único e triaxial, os acelerómetros ICP miniatura são muito utilizados para medir a resposta vibratória de veículos de voo ou modelos aerodinâmicos durante ensaios em túnel de vento.

Sensores de pressão ICP® miniatura

Para a medição de impulsos de pressão de comprimento de onda curto, os sensores de pressão micro ICP apresentam um tempo de resposta de micro-segundos que mede com precisão picos de pressão de ondas de choque de subida rápida e fenómenos de pressão de frequência muito elevada. As sondas ICP miniatura de alta sensibilidade são utilizadas para medir pequenas pressões dinâmicas, como turbulência, ruído, som e pulsações, especialmente em ambientes adversos.

Sensores de pressão piezoresistivos Endevco

A PCB é bem conhecida pelos nossos sensores de pressão piezoeléctricos ICP de quartzo; agora também oferecemos os sensores de pressão piezoresistivos da Endevco. Com desenhos adequados para medições de caudal de ar ou som de alta intensidade, estes sensores de pressão apresentam tempos de resposta rápidos e uma saída elevada para uma excelente relação sinal/ruído. Medem tanto a pressão estática como a dinâmica.

Sensores de força

Os sensores de força PCB para aplicações de aerodinâmica e aero-acústica apresentam uma elevada rigidez, resposta rápida e desempenho repetível, permitindo-lhes captar altas frequências e seguir eventos transitórios rápidos, tais como forças de reação devidas a turbulência ou ondas de choque.


Os sensores de aerodinâmica e aero-acústica são utilizados para:

  • Aviões
  • Estudos de aerofólios
  • Foguetões
  • Amortecedores
  • Veículos de reentrada
  • Ruído do motor
  • Equilíbrio dinâmico de forças
