Original Press Release:



PCB Introduces New Free Field ICP® Array Microphone for NVH Studies, Sound Pressure Mapping, Acoustic Holography and Biomedical Research



August 3, 2007, Depew, NY, USA - PCB Piezotronics (PCB®) has debuted Model 130D22, a combined ICP® free field response pre-polarized array microphone and preamplifier. The microphone is designed for measuring sound pressure levels and frequencies in the audible range, and can be used simultaneously with ICP® accelerometers to simplify test setups.

Model 130D22 also incorporates a SMB connector, which is easy to assemble, provides seamless transition for many data acquisition systems and software set-ups, and saves time when connecting multiple units, such as in a large channel array setup. When used with data acquisition systems that have 2-20 mA constant current supply, the system does not require additional power supplies. The unit has high sensitivity (45 mV/Pa), uses standard low-cost coaxial cables, and also has optional TEDS capability, which allows for ease of use, and traceability.

This acoustic test product is ideal for array set-ups (2 D Pressure Mapping, Holography); trending and frequency analysis; predictive maintenance on machinery fans, bearings and other industrial applications; white goods testing; NVH studies for automotive and aerospace,; large channel count tests; biomedical research; or general acoustic testing, where a Type 1 compliant microphone is not justifiable and the customer requires a lower cost alternative.

Model 130D22 is offered with PCB's "Total Customer Satisfaction" policy. If for any reason, at any time, you are not satisfied with our product, you can return it for an exchange or refund. For detailed specifications, drawings, or additional information, please visit www.pcb.com
