Distance measurement can be performed with contact technologies, ideal for detecting small displacements, or with non-contact LASER solutions, particularly suited to measurements on moving objects or objects subject to deformation.
LASER technology is today an established standard for the precise monitoring of long distances, thanks to its reliability even in dynamic conditions or complex industrial environments.
The instruments used for these measurements can incorporate optical or magnetic sensors, depending on the application and the accuracy required.
The integration of precision electronics and latest-generation digital sampling systems ensures high performance, measurement stability and long-term reliability, even in the most demanding contexts.

Some applications of distance measurement products
Technical insight
Distance measurement is a fundamental element in industrial applications.
Laser measurement sensors, laser distance meters, optical sensors and linear transducers are indispensable instruments for distance measurement in industrial environments.
Thanks to their precision and their ability to detect even the smallest changes in the position of objects, they make it possible to ensure maximum processing efficiency and operator safety. Moreover, thanks to the technical documentation supplied by the manufacturers, the best solution can be selected for the specific requirements of the application in which they are to be used.
In the railway sector …..
In particular, in the railway field, it is essential to know the distance between the train and the object located on the railway line, such as the control signal.
To make this possible, laser measurement sensors are used, allowing the distance between the train and the signal to be assessed simply and effectively.
Thanks to their precision, laser sensors can also be used to monitor the position of trains inside railway depots.
In the metallurgical sector …..
In the metallurgical field, distance measurement is indispensable to ensure production safety and the quality of the finished product.
Laser distance meters are used to check the distance between the parts making up industrial machinery, ensuring machining precision and the correct assembly of components.
These sensors can also be used to measure the width of steel strip or other materials, ensuring the correct dimensions of production.
In the heavy construction sector …..
In the heavy construction sector, distance measurement is essential to ensure operator safety and to assess the dimensions of the construction site.
The range of laser sensors offers a wide choice of solutions able to measure the distance, height and speed of objects.
These sensors can also be used at the design stage, making it possible to create precise 3D models representing the construction site, containing information on the distance, position and shape of the various elements.
On building sites …..
On building sites, distance measurement is essential to ensure the precision of the structures and the installation of components. Laser measurement sensors make it possible to determine the length of beams or pillars before their installation, ensuring greater processing efficiency and reducing the risk of errors.
These sensors can also be used to measure the distance between the walls and ceilings of buildings, providing information on the total surface area of the living spaces.
In the environmental monitoring sector …..
Environmental monitoring is another field in which distance measurement is essential.
Laser sensors can be used to measure the distance between buildings and mountains or trees, providing information on the distribution of features in the landscape.
These sensors can also be used to monitor ground stability, measuring the distance between the soil surface and the foundations of structures. In this way, the risk of landslides or other natural disasters can be prevented.
In the precision mechanics sector …..
In recent decades, distance measurement in industrial environments has become increasingly important in the precision mechanics sector.
Engineers need to monitor, position and control their machinery with extreme precision, and distance sensors can provide them with the information required.
In particular, LVDT (Linear Variable Differential Transformer) linear sensors and transducers are widely used for distance measurement in industrial environments.
This type of sensor works by measuring variations in the length of an iron core inside a copper coil. At the same time, a sine wave is applied to the coil, creating a magnetic field that induces an EMF (Electro Motive Force) within it.
By measuring the induced voltage, the position of the core can be determined, and therefore the distance between the sensor and the object to be measured. This technology is highly precise, reliable and robust, which makes it the ideal choice for many industrial applications.
Among the features offered are the ability to measure stroke length and absolute position with high accuracy, the choice between different interface options such as analog, digital or fieldbus, and the ability to perform high-speed measurements.
