PCB Piezotronics Introduces Surface Microphone for Aerospace Testing

Press release date: January 30, 2014

Provides Greater Accuracy in Wind Tunnel Applications

Depew, NY — PCB Piezotronics announces the launch of its new surface microphone developed for test engineers taking measurements in spaces where traditional microphones won't fit or outdoor environments and wind tunnels, where the effects of wind noise on measurements are a concern. Designed using computational fluid dynamics (CFD) modeling, the new model is a low profile microphone and surface mount pad that greatly reduces the impact of undesired air pressure on the microphone during the measurement process.

Model 130B40 is an all-in-one, prepolarized microphone and preamplifier combination with a water and dust resistant cover. Key features are its maximum dynamic range allowing measurements up to 142 dB and a 32 dBA low noise floor. Standard on this unit is TEDS v1.0.

Typical applications include: wind tunnel testing, airplane panel testing, acoustic fatigue analysis, and window surface testing. The surface microphone can be used in any flush mount application and can be embedded into a wall or mounted with adhesive on flat or curved surfaces. The height is 1/8" (3mm), making it an excellent choice for applications that require the microphone to have a low profile.

Model 130B40 is a quality acoustic measurement sensor with a small footprint and a very competitive price. The new surface microphone is in stock and available for immediate shipment.
