Microphone and preamplifier combined in one unit
PCB Piezotronics is introducing the Model 130D22, a combined ICP free-field response pre-polarised 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.
The Model 130D22 also incorporates an SMB connector, which is easy to assemble, provides seamless transition for many data acquisition systems and software setups, and saves time when connecting multiple units, such as in a large channel array setup. When used with data acquisition systems that have 2-20mA constant current supply, the system does not require additional power supplies. The unit has high sensitivity (45mV/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 suitable for: array set-ups (2D pressure mapping or holography, for example); 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.
The Model 130D22 is offered with PCB's 'Total Customer Satisfaction' policy. If for any reason, at any time, the customer is not satisfied with the product, they can return it for an exchange or refund.
