A vibration meter is a special instrument created to measure vibrations. By holding or attaching the vibration meter to a certain object, the sensor will recognize the vibration and provide information about the strength of the vibration. This tool is usually installed in pumps, screens, to buildings.
Vibration meters can provide very useful information for several industrial fields. But its most common function is to maintain work safety and security by keeping the vibrational strength of a particular object within its limits. For more details, you can read further reviews below.
How the vibration meter works
Like any other technology, vibration meter is a device that has a special way of working. Vibration meters come in many forms, each of which has its own function. However, the principle of how it works is not so different, that is, this tool needs to be attached or attached to the object to be monitored or measured for its vibration strength.
These vibrations will send out signal waves. These vibrational waves will later be transferred through cables in the mechanical system. From these waves, the vibration strength information will be converted into numbers which you can see printed on the vibration meter. This information will give you an indication of the limit or type of vibration frequency currently occurring.
There are at least two types of vibrational frequencies: low-frequency vibrations and high-frequency vibrations. Within this limit, you can also set safe limits for certain objects, for example a production machine that works automatically.

Low frequency vibration measurement
You should know that vibrations caused by imbalance, loose machine elements, or other mechanical disturbances are usually considered low-frequency vibrations. In other words, the vibration meter is a tool that can be used to detect machine problems or early symptoms of damage to be treated immediately.
There are not too many limitations for low-frequency vibration types. In fact, the size range is quite a bit. In low frequency vibration measurements, the generally used range is 10–1000 Hz which is equivalent to the ISO 10816-3 vibration measurement standard which indicates the size of the machine and the basic elements.
However, you should note that the value limits for measuring low-frequency vibrations are quite common. The range limitation can be said to be too broad and does not refer to more specific boundary information. That is why you also check the specific limits applied to the machine you are using in order to be able to identify a much more accurate vibration frequency limit.
High frequency vibration measurement
Vibration meter is a vibration measurement tool that can be applied not only for measuring low frequency vibrations. This vibration meter can also be used to measure high frequency vibrations. An example of installing a high frequency limit from a vibration meter is on a bearing. This is because bearings generally conduct higher vibrational waves.
The high frequency vibration limit standard is actually more variable than the low frequency vibration mentioned above. It also depends on the type of object being measured and its integration with the mechanical system and the machine as a whole. Even if simplified, this high frequency limit has an average range in the frequency 500–16000 Hz.
Again, you should check the bearing specifications directly. Especially considering that in the industrial market these machine bearings can have various sizes, types, and materials. The effect is clearly on the limit of the vibration frequency itself. The averages given earlier are just a rough idea of ??how high the high frequency limit is.
The above review is your introduction to a vibration meter called vibration meter. Furthermore, it is no less important for you to find out are the types of vibration meters and their specific specifications. The goal, of course, is to make it easier for you to know what kind of vibration measuring device you need and should use.
Study the manual book of the vibration meter that you have carefully so you don't make a mistake when using it. Knowing that a vibration meter is a device that has its own way of working, you can use it more optimally.
