PCB Piezotronics 130A24 prepolarized microphone

Model 130A24 is a 1/2” (12mm) prepolarized microphone and preamplifier system with a replaceable water and dust resistant cover. This acoustically transparent cover provides an unobtrusive alternative to windscreens and a more consistent response than rubber protective covers. Microphone Model 130A24 has been tested for Ingress Protection (IP) and has been determined to be IP55 by an independent test house. Equipped with a rugged stainless steel grid cap similar to our high end condenser microphones, this water and dust resistant microphone is an excellent choice for large channel array microphone applications, outdoor measurements, high humidity applications or harsh industrial settings where dust or oil splash is a concern.

Highlights:

• Water and dust resistant
• Max Amplitude: 143 dB (150 dB Clip)
• Cartridge Noise: 35 dBA
• Sensitivity: 10 mV/Pa
• Temperature: -10 to +50°C
• Polarization: Prepolarized (0V)

Applications:

• Brake noise testing
• Acoustic holography
• Beamforming
• Noise source identification
• Non-contact defect detection
• Research and development
• Acoustic tests where oil splash, high humidity or dust is a concern
