Hottinger Bruel & Kjær A/S software

Allows real-time, multi-channel FFT spectrum analysis, whether you want to perform mobility measurements, vibration diagnostics, or narrow-band analysis of acoustic signals.

Real-time, standardised digital filter-based analysis using 1/1, 1/3, 1/12 and 1/24 octaves for analysing noise, determining sound power levels, sound intensity measurements, and machine vibration monitoring.

Analyses imperfections in the moving parts of rotating and reciprocating machinery that cause unwanted noise and vibration. Relating measurements to revolutions of a rotating part improves knowledge about machinery such as aircraft and automotive engines, powertrains, pumps, compressors and electric motors.

Used for diagnostics/investigation of machinery where faults have an amplitude-modulating effect on the characteristic frequencies of the machinery, envelope analysis can be used for investigation of faults in gearboxes, turbines and induction motors.  Envelope analysis is also an excellent tool for diagnostics on local faults like cracks and spallings in rolling element bearings (REB).

SSR Analysis Type 7772 provides a steady state response analyzer for electroacoustic measurements.
