Industry's first ½" Prepolarized Low Noise Microphone

6.5 dBA capability and operates on ICP® power
A new 1/2" microphone and preamplifier system, model 378A04, from PCB Piezotronics, Inc. enables test engineers to measure extremely low sound pressure levels in a cost effective, prepolarized (0V) package.

The 378A04, is a free-field microphone that measures to 6.5 dBA (5.5 dBA typical) and is ideal for measurements commonly made in computer fan and disk drive tests, appliance noise, electric car sound quality, environmental noise, cabin noise and anechoic chamber qualification. A built-in filter is custom matched to each microphone ensuring that the sensitivity is stable and accurate between 10 Hz and 16 kHz.

This industry exclusive sensor is used with data acquisition systems that provide 4-20 mA of constant current. Prior to the release of the 378A04, engineers were forced to use high-cost, 7-pin cables and 200V power supplies to measure below 15 dBA. This microphone system uses common coaxial cables with BNC connectors and can be shared with other ICP® compatible products including: accelerometers, force and pressure sensors. Portability and interchangeability with other sensors minimizes test set-up time and reduces the cost per-channel.

PCB® carries a full complement of prepolarized and externally polarized condenser microphones and preamplifiers. The 378A04 microphone system is A2LA and ILAC accredited and CE marked. Like all PCB® microphone products, it comes with a 5 year warranty and "Total Customer Satisfaction" guarantee.

Model 378A04 is a stock item and available for immediate shipment. For additional information please visit www.pcb.com/low-noise-mic or contact Mark Valentino, Product Manager, at (866) 816-8892 or email at mvalentino@pcb.com .
