OEM laser module RF51A

Powerful laser distance measurement for integration in existing measuring systems

The RF51A is an OEM laser module to integrate laser distance measurement capabilities into existing measurement equipment. It consists of the laser measuring module and an interface board. Compared to the industrial laser distance measurement gauge LDM51, the housing and the control elements are omitted.
The OEM laser module RF51A measures contactless the distance between itself and nearly every surface and material. Up to a distance of 100 m no additional reflectors are required for measuring. The maximum distance exceeds the range of 200 m. Due to the high measuring frequency of 100 Hz also fast movements of the target can be captured.


Function

The OEM laser module RF51A operates with a modulated visible laser with low beam divergence. Newly developed algorithms and most modern technologies of the opto-electronic signal processing allow a save, highly precise and fast distance measurements that can be applied in almost all areas of machinery and plant engineering.
Other application examples are level measurement, detection of geometric dimensions like length, width or thickness and position measurement.
While developing the OEM laser module RF51A there was paid particular attention to the operation in outdoor areas with high influence of constant light by solar radiation and high temperatures.


Applications
  • Plant automation and process technology
  • Positioning applications in transportation and logistic
  • Distance measurement in mining, building, forestry and material-handling technology
  • Machine-observation and -positioning in metal industry e.g. rolling-mills, de-coiler
  • Long term observation of buildings and technical installations, e.g. churches, tide gates, docks
  • Position and height detection in crane applications
  • Level measurement in silos and heaps on materials like sand, earth, feed, cereals, cement
  • Thickness, length and width detection
