Sound and vibration recorders rely on RAID

Offering secure digital data recorders with 12Mbps recording rates and redundant 200GB hot-swappable hard disks, Sony Manufacturing Systems America Inc. is starting to roll out its SIR-3000 series. Although no technical information is available on the company's website at this time, these audio and vibration recorders are being previewed at trade shows, and approximate pricing has been established.

SIR-s000 Series recorders, slated for sound and vibration data-acquisition, are billed by Sony as secure, customizable and networkable. Their hot-swap front-mounted dual hard drives store data in a RAID One (redundant array of inexpensive disks) array.

The 200GB drives ensure that high-volume tests are captured without worrying about drive or media failure. The system provides over four hours of recording, with up to 256 hours possible using 32 channels at 1.25kHz. Disk data can also be routed to an external PC using USB or using a LAN (local area network).

As you can see from the image (above), these recorders comprise a two-deck system. A basic control module accepts bitstream data, and has no analog inputs. A 32-channel control module is priced at about $26,000. A SIR-3032i analog input unit is available; it sits under the control module. It provides a sampling frequency of 48kHz, and is priced at about $24,000.

Wider bandwidth in future

Dennis White, Sony's Digital Instruments National Sales Manager says a wideband analog input module is in the works, and will likely be ready by next spring. Dubbed the SIR-3032W, it provides a 192kHz sampling rate.

Regardless of sampling rate, SIR-3000 series recorders record data to the disk drives at the 12Mbps rate. That means you can get direct media access to specific data.

There are also built-in security features, including a NiMH (nickel metal-hydride) battery back-up. it lets tests continue uninterrupted during short power outages. The drives are also key-lockable, and can be quarantined for maximum-security.
