Which brand is good for portable vibration analyzers?

Okay, 30,000 to 150,000. Beijing, Hangzhou. Imported products; the key is the sensor – it’s best to use ones that can detect direction

The SKF bearing tester, the KD500 vibration detector, or the BH550 detector from Beijing University of Chemical Technology will all work; it depends on one’s proficiency in spectral analysis

Beijing Shengdi Zhen Tong Co., Ltd. (formerly Beijing Zhen Tong Research Institute). Contact person: 13811976498. 904 Dual-channel vibration analyzer/collector/imbalance tester. The Zhen Tong 904 is a sophisticated machine analyzer designed specifically for the condition monitoring and fault diagnosis of mechanical equipment. On the one hand, it can conduct extensive analysis and fault diagnosis of machinery and equipment (including bearings and gears) on-site ； On the other hand, various pieces of information reflecting the machine’s condition can be collected and stored for transmission to a microcomputer, enabling precise fault diagnosis, as well as the creation of equipment databases and trend analysis. Finally, the 904 can also be used for phase measurement in rotating machinery as well as for on-site dynamic balancing. Features:  Dual-channel machine analyzer (synchronous sampling)  Single-channel digital data recorder (compatible with 903), offering simpler and more convenient operation  Dynamic display of dual-channel waveforms  Lissajous plots/axis trajectories (for fundamental frequency and multiple harmonics)  Spectrum analysis (with detailed options), transfer function analysis  Measurement, storage, and retrieval of vibration amplitudes and waveforms  Envelope analysis for diagnosing bearing and gear faults  Rotation speed and frequency measurement and storage  Phase measurement, single/side on-site dynamic balancing  Large LCD display  Standard RS232C serial port for communication with computers  Comparison of on-site measured spectra with reference spectra  Diagnostic expert system (covering 70,000 types of bearings and gearboxes). 　 Typical applications:  Source analysis and fault diagnosis of defective equipment  Condition monitoring of equipment and maintenance based on its condition  On-site dynamic balancing  Parameter estimation for building and mechanical structures. Technical features:  Includes a charge amplifier, integrator, and anti-interference filter  Triggered acquisition modes available: internal/external/no trigger. The price is around 65,000; our company also uses this instrument, and it performs very well.

It’s obvious that he wasn’t asking about the professional type, but rather the one that can be used on-site. The most commonly used models include Huayang’s HY-103, etc., with a price of around 2K. The price of SKF is around 15K. Other specialized bearing manufacturers also have products, with varying prices. If one wants to choose a professional spectrum-based device, it is necessary to consult with specialized vibration detection agencies; such devices cost between 200,000 and 500,000 yuan. What’s important is the availability of an expert database, and currently these databases are based abroad – domestic ones are basically not very useful.
