While your phone may have an application to sense
vibration or how fast you can shake it, finding a way to measure the vibration of external devices was previously
quite difficult. However, a vibration analyzer can be used for inspection, production, and lab tests, and units are
being sold in large quantities now for any type of need.
These analyzers can determine if your machine or
other device is being efficient, doing damage to the surrounding area, or just provide an accurate reading for
measuring vibration!
Generally speaking, vibration analyzers can provide
accurate readings for vibration acceleration, vibration velocity, and vibration displacement. By providing 3
different types and ways of measuring what is crudely called shaking, your machinery can be monitored and analyzed
for specific inefficiencies rather than simply guessing as to what is actually the problem.
Another great feature about vibration analyzers are
their portability. Generally a handheld device, they can be easily moved and stored for later use if need be or
left on the machine. With technology advancing, some even now can fit in your pocket! These portable electronic
devices can provide a quick measurement of imbalance and can test the durability of gears and other
parts.
Other common features of vibration analyzers – also
called a vibration meter or vibration tester - include being battery powered,
having a backlit display, automatic disconnection in order to prevent wasteful battery usage, and a low battery
indicator. With all of these features, your vibration analyzer does much more than take
measurements!
Depending on the shape and size of the device, you
will be able to insert it on different parts and layers of a machine -- something to consider when purchasing a
vibration analysis device. Generally, there are 4 classes of motors that can be tested; class I, class II, class
III, and class IV. The progression upwards indicates an increase in power, and class IV possessing bearing or
stator oscillation.
With most devices, an analysis chart that indicates
what is very good, good, bad, and prohibited for vibration in mm/sec is given in order for a handy reference
that’ll fit in one’s pocket.
Protecting the motor or other parts of a machine is
crucial to running an efficient and profitable business. Therefore, it is highly important to be able to perform
regular but simple vibration analysis, and maintenance on your motor parts. Using a vibration analyzer, you can
quickly and effectively monitor your motors state and quickly decide if any problems exist!
