When registering for a seminar, please do not forget to fill out the SEMINAR REGISTRATION FORM either before or after visiting our ONLINE STORE to make sure we have all the correct information needed to properly fill out all Certificates, as well as the information we need to best tailor the seminar to meet your individual needs based on the instrumentation used at your company.
Prerequisites
- Recommended Minimum Vibration Analysis Experience = 2 years.
- Prior Experience with Spectral Analysis of Vibration data is recommended.
Overview
This three-day seminar provides in-depth coverage of Time Waveforms and how they can be used to detect a wide variety of faults, plus how they can be used to assess the severity of such faults. While the focus of the class is on vibration time waveforms, it likewise clearly shows how a different approach should be taken when acquiring and evaluating High Frequency Envelope (HFE) waveforms versus classic vibration waveforms (including a difference in setup parameters for HFE waveforms).
- Shows how to detect faults using waveform “pattern recognition” and provides real insight on evaluating fault severity.
- Proves how waveforms often are a much better indicator of fault severity - particularly those caused by bearing, gear, lubrication, rotor rub and impact-type problems.
- Includes a series of real-world case studies to clearly demonstrate how time waveforms should best be used to evaluate rotating machinery.
