Vibration Analysis Category I
VA Cat 1 personnel are qualified to perform a range of simple single-channel machinery vibration condition monitoring and diagnostics of machines
activities in accordance with ISO 17359 and ISO 13373-1.
They are qualified to:
● know of the basic principles of vibration and recognize the different units of measurement
● be able to collect reliable data ensuring appropriate standards of repeatability
● be able to identify errors in collected data
● be able to retrieve pre-defined
measurement settings for use with VA equipment and transfer data from an analysis system to a computer-based system
● be able to compare overall or single-value vibration measurements against
pre-established alert settings
● be able to identify deviations from the norm for single-value vibration values and trends
● report on visual observations of equipment condition
VA Category I - Course Content:
This course has a dedicated workbook based on the
ISO 18436-2:2014 certification program for vibration analyst category I & is designed to prepare staff for the BINDT PCN VA Cat I Certification Exam. The course is accredited to BINDT PCN CM GEN App D. The
following is covered:
Day 1
Introduction
Introduction to condition monitoring and simple failure mode analysis.
● Task 1: Selecting CM Techniques
Principles of Vibration
Basic motion:
Period, frequency, amplitude (peak, peak-to-peak, r.m.s.). Parameters (displacement, velocity, acceleration). Units, unit conversions, time & frequency domains.
● Task 2: Measuring Velocity
● Task 3: Vibration Waveform Examples (3†)
● Task 4: Vibration Waveform Descriptors
Data Acquisition – Instrumentation
Instrumentation, transducer types, locations & mounting.
● Task 5: Choice of Monitoring System
● Task 6: Recognising Transducer Types
Day 2
Data Acquisition – Measurement
Overall vibration, vibration severity, setting alarms and taking measurements
● Task 7: Vibration Severity Exercises (6†)
● Task 8: Broadband Vibration Fault Exercise
● Task 9: Setting up & Taking Measurements
Recognising Poor Data
Recognising Poor Data
● Task 10: Recognising Invalid Readings (4†)
Monitoring Program Set-up
Recognize AC induction motor, basic pump & fan combinations. Centrifugal & screw compressors, rolling mills, paper machines, process equipment, machine
tools and simple gearboxes.
● Task 11: Allocating Measurement Points
● Task 12: Identifying Machine Components
● Task 13: Recognising Asset Types
Day 3
Vibration Frequency & Signal Analysis
Be aware of the term FFT and recognize the following basic FFT terminology: e.g. number of lines, Fmax and time to sample. Recognize basic faults, e.g. bearing noise
and damage, balance, looseness and misalignment.
● Task 14: Recognising Common Faults (3†)
Frequency & Signal Analysis – Fault Finding
Recognize fault frequencies for pre-set FFT and simple time waveforms for unbalance, looseness, misalignment, bearing noise & damage. Be aware
of simple maintenance actions to rectify faults, e.g. lubrication and alignment.
● Task 15: Vibration Frequency Analysis (8†)
● Task 16: Case History – Ball Mill
Day 4
Introduction to Resonance
Methods of finding and avoiding/reducing resonance.
● Task 17: Identifying Resonance
● Task 18: Case History – Main Circ. Pumps
Corrective Action
Introduction to Unbalance, Types of Rotor, Balancing Methods, Balance Quality
● Task 19: Specifying Balance Quality
Training Examination & Course Review
Training Examination
Course Assessment
Optional BINDT PCN VA Cat 1 Exam*
* UK only – This can be arranged through SpectrumCBM or any other BINDT Approved Examination Centre (AEC)
* UK only – Applications should be made to BINDT at least 2 working weeks before the exam date
Note: The BINDT PCN VA Level 1 Exam may be taken immediately after the training, but the certificate will only
be awarded after 6 months relevant logged VA experience.
† Number of examples in a particular task - The workbook has 19 Tasks with a total of 38 separate examples
