Acoustic Impact Detection Technology
Acoustic Impact Detection is a patented state of art soundwave technology used by the Pulsar Guard 2010 acoustic sensor to detect changes in structure borne acoustic emissions from equipment and materials in motion. This movement causes impacts and frictional contact with a containing face, for example the inside of a pipe.
The acoutsic sensor is fastened to the outside of the structure, and its high frequency detection picks up these signals, which are often undetectable to the human ear. The frequency band width is wide, 100 to 600kHz, making it sensitive to the slightest changes in process conditions but also immune to audible noise or vibration caused by plant machinery.
The high frequency detection allows use in environments where there is a high degree of machinery or process noise, without interference.
