by Professional Writer Professional Writer

The main technologies of SM Instruments are visualization of sound using the sound camera, and detection of Buzz, Squeak, and Rattle using BSR Tools.

SM Instruments is a Gold Alliance Partner of the National Instruments of the US since its foundation in 2006.

The main business area of SM Instruments is developing sensors, measurements, and control instruments as well as providing engineering services, design services, and consulting services on sound and vibration applications.

And the provision of condition monitoring to wind turbine plants is also core technology of SM Instruments. Furthermore, SM Instruments offers a unique customizing service including test consulting, which provides perfect and customized sound and vibration test solutions.

Sound Camera SeeSV-S206W is a real-time sound camera that implements FPGA-based high-speed beamforming technology to enable the excellent performance even in normal noise. It can capture 25 images per second, and the high sensitivity microphone instantly detects even small noises. BSR (noise and joint) noise source detection, as well as NVH (sound, vibration, discomfort) noise sources, is visually displayed.This sound camera also provides improved acoustic performance in ultra-compact appearance by means of High-performance digital MEMS microphone of 66 channels, Wireless internet and built-in battery boost.

SeeSVReal-Time SW 2.0 is embedded in SeeSV-S206W to enhance portability.It provides a touch-based user experience for combining with a tablet computer.

FPGA (field-programmable gate array) is a semiconductor device that includes designable logic elements and programmable internal circuitry. Designable logic elements can be programmed to replicate the functions of basic logic gates such as AND, OR, XOR, NOT, and more complex decoders or combinations of computational functions. Most FPGAs contain a simple flip-flop or a memory element with a more complete block of memory in a programmable logic element.
