Understanding the importance of vibration isolation in metrology

Whether you work in research or production, accurate measurements are the key to reliable results. Proper use of advanced metrological devices can lead to improved product quality and better certainty in research outcomes. Unfortunately, the finer the resolution of the measuring instrument, the more sensitive it is to external vibrations. These vibrations can come from a range of sources, such as nearby machinery, building elevators or HVAC systems, and foot and vehicle traffic. 

No matter where these vibrations originate, vibration isolation can help. Vibration isolation systems can reduce environmental disturbances, improving the precision of measurement devices and ensuring the  most reliable results. 

Below you will learn more detail about why it is crucial to utilize vibration isolation technology in metrology. 

Vibration-Induced Errors in Measurements

Floor vibrations, inherently present in virtually all environments, can emanate from various sources, including machinery, human activities, and even natural phenomena. These vibrations can be transmitted through a building’s structure, impacting sensitive metrology equipment. 

In laser-based measurement systems, for example, vibrations can lead to inaccuracies in distance and position measurements. Research has demonstrated that increased vibration levels can significantly impact the accuracy of observations, particularly in digital surveying instruments, where precision is paramount.

Environmental Factors Compounding Measurement Inaccuracies

Beyond vibrations, metrological accuracy can be compromised by a myriad of environmental factors. These include:

• Temperature fluctuations
• Base strains
• Acoustic noise
• Transverse vibrations
• Magnetic fields
• Humidity
• Corrosive substances
• Shocks

Such factors can degrade the performance of sensors and data acquisition systems, introducing errors in measurements. For instance, temperature variations can alter the physical dimensions of an object being measured and the measurement instruments themselves, leading to significant measurement deviations. Similarly, magnetic fields can interfere with the electronic components of measurement devices, while humidity can affect the properties of the materials under measurement.

Strategies for Minimizing Vibration-Induced Measurement Errors

Given the detrimental impact of vibrations and other environmental factors on measurement accuracy, it is imperative to implement strategies to mitigate these influences. 

Methods for vibration isolation include the use of isolators or dampers to absorb and reduce the transmission of vibrations to the equipment. Additionally, environmental control measures, such as maintaining a stable temperature and humidity level in measurement environments, can further enhance measurement reliability and precision.

Precision in metrology is fundamental to the advancement of science and technology. By understanding the sources of measurement errors and implementing appropriate vibration isolation and environmental control strategies, it is possible to enhance the reliability and precision of metrological measurements. 

As measurement technologies continue to evolve toward ever higher precision and accuracy, the need to support these instruments with reliable vibration isolation technologies will continue to grow, and will continue to be a priority for the scientific community.
