Systems for measuring the position, displacement and strain of large structures can be extremely complex. Laser technology for dimensional inspections offers a simple and effective way to address these problems. Laser distance meters are devices that use a beam of light to measure the distance between two points with high precision and accuracy. This equipment can be used on structures such as bridges, buildings and ships, among many others, in numerous industrial applications.


LASER distance meters are designed to meet rigorous demands in terms of precision, accuracy and performance. They feature a dynamic range of 100 meters or more depending on the model chosen. Even though the cheaper versions have a lower range, they still have the advantage of taking fast and accurate measurements without human intervention.

LASER distance meters provide vital information on how the structure behaves over time and eventually deteriorates. They can measure changes in the width or height of structures, as well as gradual displacement or deformation caused by extreme load or vibration. The improvements integrated in RODER solutions allow for this purpose the automatic analysis of the orientation and the automatic detection of obstacles along the path of the laser during the real-time monitoring operations of large structures.

Laser distance meter technology can also be used successfully in difficult conditions, such as dusty, watery or extreme temperature environments. All RODER units are compatible with the international standard which guarantees all devices to dust and liquid particles superior to other products on the market. As a result , RODER sensors can easily be used in harsh environments and extreme conditions that other products can not withstand .

Systems that measure the position, displacement and deformation of large structures have become more common in recent years. One effective way to achieve this is through the use of laser distance meters (LDMs). These devices use laser technology to measure distances between specific points on the surface of the structure and provide accurate data. The main advantage of using LDM in the measurement of large structures is the possibility of obtaining accurate results in a very short time. Since there is no physical contact with the structure, the data collected is more reliable than with other methods.

Another benefit of using LDM for measuring large structures is that it makes determining position, displacement, and strain easier and more cost-effective than more traditional methods such as contact devices or wire encoders. By using low-power lasers, the process can be completed safely without damaging internal components or the surrounding environment, and without endangering operators. Furthermore, it is possible to repeatedly take readings over time with a high degree of accuracy, thus making it possible to monitor the evolution of the dimensions and dynamic behavior of the structure over time.

Laser distance meters are ideally suited to measuring large structures as they are totally independent of environmental conditions such as direct sunlight or any environmental contaminants. This reliability allows them to operate in any outdoor and indoor environmental condition without compromising the accuracy of the measurements taken. Furthermore, since LDM units are small enough to be mounted even on small surfaces, they can also be installed on the lower parts of structures where direct access is not feasible.

When all these beneficial products are considered from the use of LDM to measure the position, displacement and deformation of large structures, it becomes clear that this technology represents a valid alternative to other traditional methods. Of particular interest for industries that need to monitor and keep track of all the dynamic assets of their structures is the fact that LDM technology offers updated and frequent information on the actual status of the monitored structures with very high precision
