There are numerous vibration sensors, used for vibration measurement, and the primary principle here is to measure the velocity, expansion and acceleration of the vibration. The frequencies of most vibrations may vary between 10 Hz and 1 KHz. Thus the vibration measuring instrument must be able to record vibrations at different points of the item being tested or measured.
To take a vibration measurement, you will have to attach a sensor that can easily detect the pattern of the vibration, from the machine that is being monitored. The accelerator will produce an electrical signal that is directly proportional to the vibration acceleration from the material being measured. The acceleration signal measured by the accelerometer is converted into velocity signal, and the signal can be displayed in wave forms.
The resonant frequency measurement equipment is precision equipment works by determining the longitudinal, Torsional, and Transverse resonant frequencies of an item being measured. The Resonance frequency meter has five main features, these are;
Vibration can expose a lot of defaults and problems, and one of such is mechanical imbalances. When a heavy spot located on a rotating component is causing vibration, especially when an unbalanced weight is rotating, centrifugal force will be created, this will reduce the lifespan of the device’s bearing. Vibrations can also cause misalignment, and shaft run-out, hence vibration measurement is important to prevent a situation known as parallel misalignment. Vibration measurement is also needed to detect or prevent wear and tear.
Bearings, drive belts and gears can become worn-out and cause vibrations, especially when the bearing rollers travel through the worn-out area, the gear tooth may also become chipped, and cause vibration. Looseness is another issue that can be resolved quickly through vibration measurement. When vibration goes unnoticed for a very long time, it may result in the gradual destruction of certain components, especially the stationary ones. Vibrations are symptoms of fatigue in equipment, especially those that have not been serviced for a very long time.
Measuring vibration earlier can help prevent all these problems, and help save the costs of repairs or replacing the devices. Early vibration detection can also improve the output and efficiency of devices and machines, especially when the issues causing the vibrations are resolved within the shortest period of time.
The benefits of vibration measurement can thus be said to be;
The safety of a machine user is as important as the output of the machine as well as return on investment (ROI)e.
A typical sound level meter is a measuring instrument used in assessing noise and sound levels by measuring the pressure created by sounds. The sound pressure measured is also referred to as the Sound pressure level (SPL). Noise meter also referred to as Decibel meter,
The sound level meter is particularly ideal for educational applications, especially in the measurement of 4 Parameters- Humidity, temperature, sound and light. The measuring range of a sound meter can vary from 30-130dB.
Vibrations can cause serious problems to different materials, most especially to machine shafts, bearings and the performance of the hard disk. These disturbances measurement is the use of vibration reading to analyze displacements, linear velocity, and acceleration. For these reasons, vibration measurement can be applicable in many ways, these include;
