Distance, position and level monitoring with LASER distance meters and visualization on giant displays

industrial laser distance meters for distance and position measurement with remote display on monitor

RODER presents the new series of REDAM LDM giant displays to create display and monitoring systems to be connected to LDM series LASER distance meters.

The REDAM LDM series has been specially developed for the connection with LASER LDM series distance meters allowing the real time display of the measurement made by the LASER distance meter.

The visualization takes place on a giant display or transmitted to remote terminals through Wi-Fi or ethernet networks.

The visualization takes place on a giant display visible even at high distances.

All the displayed measures can be compared with tolerance thresholds in order to generate alarms in case of out of tolerance upon exceeding certain thresholds or visual signals capable of guiding the operator to any adjustment operations (red value represents an out of tolerance, value yellow represents a warning attention signal, green value the measurement is acceptable).

Applications

Level measurement in tanks, silos or large containers with level display on remote monitors. The LASER sensor allows a precise and fast measurement even of liquid products where the surface reflection index is such as to allow the detection of the LASER spot. The LASER distance meter is a valid replacement for the contact distance meter or the ultrasonic wave detector.


Measurement of size, distance or position of large objects in the metallurgical and iron and steel industry. Real-time communication of position and distance to PLC, HMI or process control devices. With the LASER distance meters it is possible to check the coil diameter during winding for programming the acceleration or deceleration ramps. It is possible to detect the edge position for tracking the movement or the size, thickness, width and length of billets and slabs.


Measurement of length, diameter, ovality and position in the wood sector. With the LASER distance meters it is possible to measure the position of logs or blocks of material before processing. The position, thickness, length or diameter data can be transmitted in real time to PLC, HMI or SCADA systems. The irregularity of the wood surface is not a problem as the LDM series LASER distance meters constantly correct the operating parameters in order to guarantee a precise and reliable measurement.


Dimensional inspection in the paper and textile industry. Control of loop and position of the belt or carpet even in the presence of materials with a change of color or surface appearance. The distance measurement can be transmitted in real time to the line controller (PLC or SCADA) or displayed on a display or on a giant monitor.


Measurement and dimensional control in the metal industry. The characteristics of the LDM series LASER distance meters allow a precise and reliable measurement even in the presence of high temperatures, in the presence of fumes and vapors or on hot surfaces. The problems of heat or light emission by the target to be detected can be eliminated or greatly mitigated with the use of protective cases or with the installation of optical filters


Dimensional control in the metallurgical sector on both hot and cold applications. The LASER distance meter can provide in real time the position, distance and size (thickness, width, length) of slabs, blooms and billets both at room temperature and at high temperatures. The problems of heat or light emission by the target to be detected can be eliminated or greatly mitigated with the use of protective cases or with the installation of optical filters


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. The use of intelligent data loggers allows constant and continuous monitoring even over observation periods of weeks or months. Remote data transmission also allows the monitoring of multiple measurement points or multiple structures from a single observation and control point.

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.
