Vibration Calibrators

A-Z: A Guide to Using and Applying Vibration Calibrators in Industry

In machine maintenance and condition monitoring, a vibration meter is an essential tool for early fault detection. However, to ensure the accuracy of these meters, a specialized tool is needed for checking and calibration: the vibration calibrator. This article will help you understand the role, usage, and related standards of this important device.

What is a Vibration Calibrator and Why is it Necessary?

A vibration calibrator is a device that generates a standard vibration with a specific amplitude and frequency. By attaching a vibration sensor or probe to the calibrator, users can quickly check the accuracy of their vibration meter before use.

Why is a Calibrator Needed?

Ensures vibration measurements are always within the allowable error range.

Reduces the risk of incorrect maintenance decisions due to inaccurate data.

Complies with requirements in quality management systems (ISO, manufacturing plants, labs).

Common Applications of Vibration Calibrators

- In industrial maintenance: Quickly check the condition of meters before on-site use.

- In most laboratories: Perform periodic calibration for vibration measurement devices according to international standards.

- In manufacturing: Ensure vibration meters coming off the production line meet technical specifications.

Basic Guide to Using a Vibration Calibrator

Using a calibrator is quite simple, and you can perform the process on-site. With high-quality calibrators distributed by EMIN such as MMF VC21 or famous measurement brands today such as PCE, Huatace, and ACO, the entire process only takes a few minutes.

Prepare the device: Place the calibrator on a flat, stable surface.

Attach the sensor: Mount the probe or accelerometer of the meter onto the calibrator's designated position.

Set parameters: Select a standard frequency and amplitude (e.g., 10 m/s² at 159.15 Hz – a common reference value).

Compare results: Read the value displayed on the vibration meter and compare it with the standard from the calibrator. If the deviation is within the limit (usually ±5%), the device is acceptable.

International Standards Related to Vibration Calibration

ISO 10816: Guidelines for the evaluation of machine vibration.

ISO 16063: Standards for methods of calibrating vibration sensors and meters.

ISO 17025: Requirements for the competence of calibration and testing laboratories.

Some Notes on Use and Maintenance

Avoid impacts and dropping the calibrator.

Periodically check the battery and power cables.

Store the device in a dry, clean place, away from moisture and mold.

Calibrate the calibrator itself periodically to maintain accuracy.

We hope this information has helped you better understand the importance of calibrating your vibration meters. Investing time and resources in this process is a smart investment to protect assets, optimize maintenance costs, and ensure workplace safety.
