The measurement of deformation, the verification of vibrations, displacements and deformations of large structures such as bridges, buildings and dams it is an extremely important process to ensure its safety and structural integrity. An essential measuring tool in this process are LASER sensors, also known as LASER distance meters.
LASER sensors are non-contact measuring instruments, which allow for extremely precise measurements of dimensional variations in different materials and structures. These sensors are able to detect even the smallest variations, even in the presence of vibrations and movements.
LASER distance meters are able to calculate the distance between the sensor and the object under examination, thanks to the emission of a beam of light. The sensor will detect the beam reflected from the object, from which the distance between the sensor and the object can be obtained.
The uses of LASER sensors are manifold, ranging from the verification of deformations in large structures, to the measurement of geometric tolerances and the detection of small dimensional variations.
LASER sensor technology is increasingly advanced, and more and more companies and organizations are adopting these measuring instruments to guarantee the safety of their structures. Thanks to their ability to measure displacements and deformations in real time, LASER sensors are an indispensable tool for the verification of large structures.
Furthermore, the non-contact measurement is an additional advantage of LASER distance meters, as it is not necessary to come into contact with the object under examination. This means that the process of verification can be done at a great distancewithout coming into contact with the inspected surface.
Ultimately, LASER sensors and LASER distance meters are extremely important measuring instruments for verifying vibrations, displacements and deformations in large structures. Thanks to their ability to detect even the smallest dimensional changes, these tools have become indispensable for guaranteeing the safety and reliability of large structures that surround us.

Insights
I laser distance meters proposed by INNOVACHECK provide highly accurate and reliable distance measurements with pinpoint accuracy and fast response times, ideal for position, displacement and velocity measurements.
Laser distance meters are easy to install, they do not require recalibration and require minimal maintenance over their lifetime.
The non-contact nature of the laser sensor eliminates potential safety or contamination issues associated with object measurement, due to contact measurement methods.
The flexibility of laser distance meters allows them to be used in a variety of applications, such as monitoring the positions of cranes and gantries, monitoring and measuring multiple points simultaneously.
The ability to measure distances up to 300m makes them suitable for large construction sites or maneuvering areas where more traditional level sensors may not be usable due to the limitations of their range.
Laser distance meters they are able to measure horizontal and vertical distances without the need for direct contact or direct access, making them ideal for hard-to-reach places or awkward locations within warehouses or maneuvering areas.
They are extremely affordable compared to other non-contact sensors - they can be purchased at a lower cost compared to traditional rope sensors or radar systems which require additional hardware and wiring costs.
Rated to IP65, these laser distance meters can be used outdoors even when exposed to rain, snow and other extreme environmental conditions (with suitable enclosures), allowing for greater flexibility during installation and operation in a range of applications within industrial plants and mining operations where robustness is essential in extreme external conditions (contact our technical support for more information).
Remote control and remote surveillance
By allowing remote control via a digital input/output connection configuration, it is possible to control operations from a safe distance which reduces the risk factors linked in particular to the entry of personnel into confined or dangerous spaces ( automatic warehouses, dangerous areas, high heights )
Measuring the position of an overhead crane or crane has never been easier thanks to the LDM42 and LDM300 LASER distance meters.
These precision instruments not only measure accurately and reliably, but also display real-time data on remote monitors via Ethernet or Wi-Fi.
The LDM42/LDM302 laser distance meters open up new possibilities for monitoring logistics operations, so you know exactly when it is time to implement corrections or change control strategy.
RODER's LDM42/LDM302 laser distance meters are the perfect tool for measuring the position of gantries, cranes, sluice gates, beams and carpentry structures. They offer unmatched accuracy and reliability, with readings consistently accurate to within 1 millimetre.
Remote control
Data can be displayed in real time on remote monitors via Wi-Fi or Ethernet networks, so you don't need to be on site to get up-to-date readings. The data also allows for position and anti-collision monitoring, in order to guarantee the safety of operators, equipment and structures.
Another advantage of using the LDM42/LDM302 laser distance meters is the ease of installation and operation. The gauges can be easily mounted to shed walls, crane gantries or manipulator arms and the setup process is simple enough for anyone to do.
Operation is completely non-contact, so no maintenance is required, other than occasional checks as needed. This makes them an effective choice for both large-scale industrial applications and small installations.
With the laser distance meters offered by INNOVACHECK, even environmental factors such as temperature variations do not affect the readings, as they use a reflection optical technology. This means that regardless of the extreme conditions, theAccuracy remains constant over long periods of time, with minimal effort on the part of the user.
