Description
- APPLICATIONS: Detects infrasound in the 0.05 Hz to 20 Hz band that is generally inaudible to the human ear. Applications include monitoring wind turbines, machinery noise, building noise, elephants and other large animals, meteors, avalanches, volcanoes, earthquakes, cryptozoology studies of big foot and sasquatch, and paranormal investigations.
- COMPONENTS: For laboratory, field, school, office, or home use to record and analyze infrasound. This infrasound monitor comes with a 15 ft (4m) serial cable, 15 ft (4m) of 1/8 inch ID plastic tubing, a USB-Serial adapter, and a CD containing Windows software and software manual.
- PC CONNECTION: The INFRA20-LED must be attached to a PC to log, analyze, and display infrasound data, but other programs can run on PC while the infrasound data logging program is running. The Amaseis software works with Windows XP and above. The seismic data logging and analysis program AmaSeis is supplied on CD or USB drive. Also runs with the new jAmaseis seismic software that runs on Windows, Linux and MAC OS.
- SENSOR: The infrasound sensor utilizes a differential pressure sensor with 1/8 inch ID tubing connection that is located on the side of the box. This tubing makes it possible to separate the monitor from the infrasound sensing location. The monitor is self adjusting, and never needs alignment, zeroing, leveling, or any other adjustments. Resolution is 0.001 Pascal (0.01 microbar). Range is 25 Pascals. Sampling rate is 50 sps. Serial output format: 9600bps, 8N1, 16 bit ASCII.
- LED LIGHTS: The INFRA20-LED has the same specifications as the INFRA20. In addition it includes 4 colored LED that indicate the SPL dB infrasound level visually. It can also operate on a 9v battery without any computer connection.
The Infiltec Model INFRA20-LED infrasound monitor connects to a PC to record, display and analyze infrasound in the 0.05 Hz to 20 Hz band that is below the human hearing range. Infrasound is produced by wind turbines, helicopters, meteors, avalanches, volcanoes, large animals like elephants, etc. The INFRA20 is designed to provide infrasound monitoring for lab, home, school and field use in a compact, portable, and rugged package that is less expensive and easier to use than conventional designs. The INFRA20 does not require any power supply or assembly or enclosure or adustment; including alignment, damping, zeroing, etc. The INFRA20 works with the standard AmaSeis Windows based seismic software, and with the new jAmaSeis software for Windows, Linux and Mac OS.
