In the demanding world of construction and mining, precision in measurements is not a luxury, but an absolute necessity.

Therefore, the right choice of monitoring instruments ensures the safety of infrastructure and compliance with legislation. In this guide, EXORIXI S.A.. analyzes everything you need to know about the two main tools of the industry. These are vibrographs and accelerometers.

What is their main difference?

Although many use the terms interchangeably, there is a clear technical difference. Specifically, a vibrograph is a complete recording system that includes sensors, a memory unit, and analysis software. In contrast, the accelerometer is the specialized sensor that converts the movement of the ground or a structure into an electrical signal.

For example, if you want to measure the effect of an explosion on a neighboring building, you need a vibrograph that incorporates three accelerometers (for the three axes of motion: X, Y, Z).

Technical characteristics that determine success

When considering the purchase of equipment, you should focus on specific specifications. In addition, modern vibrographs and accelerometers should offer:

  • Frequency range. Capable of recording from very low to high frequencies (e.g. 1 Hz to 500 Hz).

  • Dynamic range. High sensitivity to microvibrations but also resistance to high accelerations.

  • Autonomy and connectivity. Capability of remote data transmission via 4G/5G and long battery life for field work.

  • Certification. Compliance with international standards such as DIN 4150-3.

Who are the best for technical projects?

The choice depends on the scope of application. As a company, we have the most well-known and reliable brands and with over 35 years of experience we know exactly how to choose correctly depending on the requirements of each project. In particular, these instruments offer unparalleled reliability in:

  1. Urban demolitions. Where real-time vibration monitoring prevents damage to adjacent buildings.

  2. Large engineering projects (tunnels, bridges). For continuous control of structural integrity.

  3. Quarrying operations. To optimize blasting and reduce social disturbance.

Prices and cost factors

The price of a vibrograph or accelerometer varies depending on the technology and support that comes with it. Of course, a cheap sensor may look attractive, but it often lacks in accuracy and analysis software. Therefore, investing in branded equipment reduces the risk of incorrect measurements that could lead to legal complications or business interruption.

Frequently Asked Questions (FAQ)

What is the difference between a vibrograph and an accelerometer?

The vibrograph is the complete recording system, while the accelerometer is the specialized sensor that measures the acceleration of the movement. For a complete measurement, we use vibrographs that incorporate triaxial accelerometers.

What are the best vibrographs for technical projects?

The best choices include internationally recognized and certified brands that ensure absolute accuracy. In particular, EXORYXI S.A., based on over 35 years of experience in the industry, equips projects with the most well-known and reliable brands worldwide. Therefore, these instruments guarantee high resistance to adverse field conditions, absolute compliance with the DIN 4150 standard and easy data management via cloud.

How does price affect measurement quality?

The lowest prices on anonymous vibrographs often hide deficiencies in the calibration and durability of the sensors. Purchasing branded equipment from EXORIXI S.A. ensures valid reports that are accepted by public authorities and regulatory bodies.

Is the use of accelerometers mandatory in blasting?

Yes, Greek legislation and international safety protocols require continuous vibration monitoring. This is to ensure that vibrations remain below risk limits for surrounding structures and the environment.
