Best Vibration Analyzer

You can find vibration analyzers on the market with different number of input channels, the most common being 1 to 2 channels.

Recording 2 channels simultaneously is usually enough for functions like balancing, phase analysis.

Single channel analyzers are not common anymore since they are unable to perform necessary techniques necessary for some of the most important faults, like misalignment, Bode and balancing.

FFT

Spectrum, is the heart of an analyzer, almost all analysis functions need it inside their calculation. Not to mention FFT measurement tools and Window functions: Rectangular, Hann, Hamming, Flat Top.

Time Wave Form​

Vibration analyzers draw this chart with the signal as it arrives from the sensor. It is not used very often, however some secondary functions like Circular Time Wave Form are useful to detect patterns in gearboxes or bearings.

Measurement parameters​

Acceleration, Velocity, Displacement and Acceleration Envelope (Demodulation or equivalent, useful for early bearing fault detection)

Vibration Data Collector

A good vibration analyzer should also be a vibration data collector. At least it should have a mechanism to store and organize the recordings of the machines to store a history and trend of the machinery. This is one of the main factors to consider because consider that you will be dealing with this part of the system EVERY day. Having an intuitive and easy-to-use database interface is vital to avoid wasting time later.

Machinery database​

Will store all the information related to your machines and all your recordings over time.

Envelope alarms

The theory tells us the ideal vibration levels for some of the machinery in the industry, but what will you do if you do not know what the ideal value is? This tool will let you know the moment the vibration increases in any of its frequencies. It wraps the full spectrum and rings an alarm whenever any frequency grows more than the percentage you configured.

Reporting tools

Reports can be very tedious if you create signal by signal, value by value. Automatic reporting saves considerable time.

Dynamic Balancing

Dynamic balancing is a functionality which is present in the vast majority of equipment usually as optional, however, considers that imbalance is one of the most common causes of vibration in the machinery, wouldn’t it be good to correct the problem instantly?

Phase Analysis

Phase analysis requires you to record at least 2 channels simultaneously in order identify the direction of motion compared to each other. This function is mandatory to fully diagnose misalignment among some other faults.

Bearing database

This function is important because bearing vibration analysis identifies fault frequencies related to bearing geometry. Thus, you have a complete bearings database to obtain manufacturer information to perform fault calculations.
