SVAN 912AE - Multi-Function Handheld Analyser
 |
OVERVIEW
The SVAN 912AE is all digital, Type 1 sound & vibration meter and analyser. It is intended to acoustic measurements, environmental noise monitoring, occupational health and safety monitoring, human vibration measurements and machine health monitoring. It can be used by acoustic consultants and safety engineers, in Public Services, in acoustic laboratories, in industry, in R&D departments etc...
Now, using power of the new digital signal processors the SVAN 912AE can perform real time, narrow band (FFT) and 1/1 octave or 1/3 octave analysis (including statistical analysis) up to 45 kHz.
The SVAN 912AE has built-in all necessary weighting filters. Measurement results are displayed as RMS and Peak values, statistical diagram and level v. time or spectrum. Measurement results can now be stored in 4 or 8 MB Flash Disk and easy downloaded to any PC with the RS 232 interface and SvanPC software. New USB 1. 1 interface brings the totally new possibilities of the very fast link to the PC environment. It creates unique combination of the extremely powerful autonomic instrument and real time PC system. Additional interface with AES/EBU protocol ensures data exchange with other digital audio signal processing systems. Using this interface and SV 06A or SV 08A modules, the SVAN 912AE can be also expanded up to four-channel measurement system. Advanced measurement functions like: reverberation time, balancing of rotating mass, pure tone detection etc. will be available as options. Thanks to built-in rechargeable battery and rugged but lightweight construction, the SVAN 912AE can be used for field measurements in hard environmental conditions for at least eight hours.
The SVAN 912AE can be delivered with wide range of accessories that are necessary for sound and vibration measurements: microphones, microphone preamplifiers, sound level calibrators, accelerometers, calibration exciters, cables etc.
