Micro-Epsilon offers laser distance sensors for large measuring ranges.
The optoNCDT ILR2250 laser distance sensors are designed for large measuring ranges. They are used in industrial environments and offer different measuring modes for optimal exposure on demanding surfaces. These sensors provide precise measurement results with high signal quality independent of the surface, whether it is on metals, plastics, paper or textiles.
In factory and plant automation, large distances between the sensor and the measuring object must be monitored. Micro-Epsilon has developed the optoNCDT ILR2250 laser distance sensor for these measurement tasks. The sensor covers measuring ranges up to 100 m without a reflector. When using a reflector, the measuring range can be extended up to 150 metres. Their robust aluminum die-cast housing protects the sensor against harsh environmental conditions. The integrated optical interference filters provide the ILR2250 sensor with very good ambient light suppression. Therefore, measurements are also possible in outdoor areas, such as for monitoring the travel paths of crane axes or drone-based distance measurements. Their innovative technology enables demanding measurements on different surfaces, such as paper or plastics, as well as metals and textiles.These advantages make the optoNCDT ILR2250 ideally suited to many industries such as the steel industry, and transport, logistics and conveyor technology.
The measuring principle
The optoNCDT ILR2250 works with a red semiconductor laser of a wavelength of 655 nm and is assigned to laser class 2. Its measuring principle is based on the phase comparison measurement. The sensor emits high-frequency, modulated laser light. The light that is returned to the sensor is phase-shifted due to the reflection at the measuring target and is compared to the reference signal. The value of the phase displacement enables the determination of the distance with high accuracy. The measurement is triggered either by a control unit, a PC, a trigger signal or the auto start function.
Put in the right light
The laser distance sensor from Micro-Epsilon offers outstanding signal stability on numerous surfaces, which enables measurement results down to millimetre accuracy. This innovative sensor technology is almost independent of the material on objects with a reflectivity from 6 to 100 %. Therefore, it’s suitable for versatile applications on different surfaces.
The optoNCDT ILR2250 in practice:
- Filling level measurement in silos
- Precise acquisition of coil diameters
- Diameter monitoring on seamless rolled rings, etc.
Conclusion
The optoNCDT ILR2250 laser distance sensors use the phase comparison method and detect measuring objects at distances of 0.05 m up to 150 m with maximum signal stability. This is achieved with a linearity of ±1 mm and a resolution of 0.1 mm. Thanks to their high accuracy and robustness, the laser distance sensors from Micro-Epsilon are designed for precise distance measurements in industrial environments. Models with integrated heating are available for outdoor use. The innovative sensors detect the distance to remote objects. Depending on the distance and accuracy requirements, the measurements can be carried out with or without reflector film. The integrated AUTO measurement mode enables reliable measurements even on dark, partly reflecting and remote measuring objects. Therefore, the ILR2250 sensors can be used for distance measurements on numerous surfaces. Simple and fast alignment of the sensor is made possible by the integrated mounting plate with four threaded pins. Due to their properties, the sensors are used in logistics and automation technology, the metals industry and production monitoring.
