Vibration Meters

GAOTek offers a wide and dynamic selection of high-quality, affordable and accurate Vibration Meters. A vibration meter is used in inspections, manufacturing, and production to measure vibration and oscillations. The main function of a vibration meter is to measure displacement, velocity and acceleration of a vibrating body.

GAOTek’s vibration meters are known for their quality and accuracy and are for sale to the United States, Canada and globally. We offer a wide selection of meters to best suit your needs whilst still providing accuracy and affordability.


The following components work together to measure vibration in a vibration meter:

  • An accelerometer is connected to the charge amplifier that consists of an input impedance of several GΩ eliminating the need of a separate preamplifier.
  • An integrator measures the velocity, displacement and acceleration.
  • High pass and low pass filters that can be adjusted to limit the frequency range of the instrument to the range of interest. This reduces the possibility of an interference from both the high-frequency and the low-frequency noise. After the signal is amplified, it is rectified to a DC signal that is displayed on the meter or chart recorder.
  • The detector can be an adjusted to measure the average RMS level of the signal or to register the peak to peak level if maximum value is required. This is a useful feature for measuring mechanical shocks or any short vibrations.
  • After passing through the linear part, the signal is made to pass through the logarithmic converter. As the signal is converted, a measurement in the logarithmic measure is displayed.
  • The external bandpass filter can be connected to a vibration meter for frequency analysis. The output sockets allow the signal to be fed to the oscilloscope and the tape recorder or level recorder.

Reading the frequency - The instrument is based on a single vibration level that is measured over a wide frequency band. To know the individual frequency, individual frequency components that make up the band signal are required to make up the wide band signal used for frequency analysis. The filter used passes only the signal parts in narrow frequency band. The pass band of the filter is moved sequentially over the whole frequency range of interest to obtain separate vibration level for each individual band. The filter can consist of a number of individual, fixed frequency filters. These are scanned sequentially by switching.

GAOTek’s vibration meters meet the ISO 2954 standard, used for periodic measurements, to detect out-of-balance, misalignment and other mechanical faults in rotating machines.

  • Bluetooth option: The output can be connected to a Bluetooth source.
  • ISO 2954 standard compliant:Our vibration meters are ISO 2954 compliant, making vibration measurements of all rotating machinery safe and easy for quality control, commissioning and predictive maintenance purposes.

Vibration meters are used for vibration testing. Vibration testing is done by introducing a forcing function into a shaker. A DUT or device under test is attached to the table of the shaker. These tests are performed to examine how a device responds to vibration. There are different types of shakers used to shake the DUTs. For low frequency, electrohydraulic shakers are used. For high frequency forcing, an electrodynamic shaker is used. At least one or more input or control points are located on DUT’s side of the fixture which is kept at a specified acceleration. The other response point experiences maximum vibration level or minimum vibration level. To keep the system from becoming too noisy, it is often desirable to achieve anti-maximum vibration level.

Vibration testing is also used to reduce strain on certain parts due to vibration modes caused by different kinds of vibration frequencies. Sinusoidal and random sine tests or one-frequency-at -a -time tests are commonly used to check the structural response of the DUT. A random or all frequencies at one test is generally used to test a device in a replica of a real world environment, such as road inputs to a moving vehicle.
