By integrating the "CF-0722 Tracking Analysis Option" with the CF-7200 Portable 2-channel FFT Analyzer, high-speed and high-precision on-site constant ratio tracking, constant width tracking, time tracking, and recording with rotation information are possible. The recorded record data (ORF files) can also be analyzed offline using the XN-8100 Reportizer, etc. The CF-0722 Tracking Analysis Option expands the range of applications for the CF-7200 FFT Analyzer.
For rotating machinery such as engines and compressors, which must cover a wide range of rotational speeds from low to high, the resonance between the natural frequencies of each component (rotating shaft, gears, brackets, etc.) and the rotational speed is the most important issue. In the case of torsional vibrations in large generators, resonance can generate large excitation energy that exceeds the allowable stress, potentially leading to major accidents and destruction. Furthermore, vibration and noise countermeasures require detailed analysis of at what rotational speed vibrations and noises become significant, and from which components of the rotating machinery vibrations and noises are generated. "Rotational tracking analysis" is an effective analytical method for analyzing the generation of noise and vibrations synchronized with rotation. By combining the CF-7200 FFT analyzer with the CF-0722 option, high-speed and high-precision tracking analysis can be easily achieved on-site.
