Position measurement on overhead traveling cranes with anti-collision function. The LASER distance meters of the LDM family allow the real-time detection of the position and distance on bridge cranes and cranes ensuring the anti-collision function. The installation of the LASER distance meters also allows the parallelism to be detected or the two lateral carriers not to synchronize. The display of the position, distance or positioning differential can also be viewed on giant monitors or it is possible to generate alarms or remote signals on the control systems.


Supervision of the railway infrastructure. Detection of the position and speed of trains and moving parts. The ability to detect distances even up to 3 km allows the detection of objects that move over large distances or that must be intercepted at great distances. The ability to work on even very different surfaces or with very high variations in color and reflectivity allows the detection of distance, position and speed even on very different objects.


Measurement and control of the position, deformation and vibrations of large structures or located at very large distances.
The ability to work on even very different surfaces or with very high variations in color and reflectivity allows the detection of distance, position and oscillation even on very different objects.

Learn more about LASER distance meters

The LASER LDM family of distance meters consists of a series of optoelectronic distance measuring devices for industrial applications with analogue interface (from 4 mA to 20 mA) or digital (Ethernet, Profinet, Profibus, RS232, RS422).

The LDM series LASER distance meters are used for the precise measurement of distances from a few meters to three kilometers. The distance measurement represents aconsolidated application for laser technology.

These optical sensors use LASER (pulse or modulated) light to measure distances, heights, lengths, levels and positions in a non-contact process. To achieve this, all components work together in a perfectly coordinated overall system.

This system consists of a laser emitter, optical transmitters and receivers, photosensitive diodes and sophisticated electronics and algorithms for time measurement or phase measurement. We use different optoelectronic principles for our measuring devices, such as time of flight, phase comparison and back-mixing LASER pulse. These methods allow singles accurate measurements to the millimeter, and measuring ranges up to several hundred meters. Using our LASER distance meters is possible measure on natural surfaces or on special reflectors obtaining fast and precise results.

LASER distance meters work using visible or invisible optical radiation and are classified in accordance with current regulations in class 1 or 2 (safe classes for operation even without protective glasses).

The compact construction allows easy installation of the LASER distance meter even where space is limited or in industrial applications. All devices offer standard interfaces, analog or digital data output and parameterizable switching outputs. The family of LASER LDM distance meters is particularly used for applications in the industrial sector with analog (4 - 20 mA) or digital (Ethernet, Profinet, Profibus, RS232, RS422, SSI).

Multisensor monitoring applications

With the REDAM-LDM family of remote displays it is also possible to monitor processes with multipoint sensors and with a multi sensory acquisition network.
