What is a meter of vibration?

The

vibration meter measures changes in the basic vibration samples of the machinery components. These changes may indicate mechanical disorders that may result in expensive repairs. These devices are usually manual and provide different types of vibration analysis that may include recording, displacement and speeds together with internal temperature data. Displays of liquid crystals provide values ​​that can be stored in a vibration meter for a future link or transferred to computers to monitor conditions.

Maintenance engineers can use vibration tools to monitor compressors, fans, gearboxes and pumps. The use of vibration meters regularly scheduled, as part of the power monitoring, points out the staff when the parts are released or worn. Many vibration meters show measuring the vibration of rotating engine components. Some devices may require actual contact with a machine part while other information transmission by using LAServe beams and reflective tapes. These tools not only measure the amount of vibrations, but can also provide the number of rotations per minute.

Vibration meters are often designed to provide readings when selecting user units. Movement measurement is generally displayed in inches or millimeters, speed measurement is marked as thumbs or millimeters per second, and the acceleration measurement is usually referred to either by legs or meters per second. Some models of vibration measures provide measuring acceleration and speed, while others include shift values.

The shift generally refers to an amplitude or distance of a change from a particular reference point. Reading can also indicate an average shift or maximum level. Speed ​​is the speed change and acceleration indicates the speed of changing speed. Vibrations of relocation usually occur in low fThe propagation range, velocity vibrations usually occur in low to medium frequency and acceleration vibrations are generally anywhere between low to high frequency levels.

Frequency levels

numerous vibration meter are generally displayed in Hertz (Hz) and Kilohertz (KHZ). Some models can provide the same frequency range for relocation, speed and accelerate vibration. More expensive models usually measure different frequency ranges for each type of vibration. For example, reading frequencies can range from 10 Hz to 500 Hz, speed frequency from 10 Hz to 1 kHz and acceleration frequencies from 10 Hz to 10 kHz.

movement analysis is done by comparing stored readings on vibration meters in the form of numerical or graphics displays. Some units include computer software and others offer optional computer programs. Data transfer to a computer program through a transfer cable generally allows users to evaluate in more detailOrmation.
