LDM51A-x Lumos

Advanced Laser Distance Meters for harsh environments

The brand new measurement gauge LDM51 Lumos 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 LDM51 Lumos 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 LDM51 Lumos there was paid particular attention to the operation in outdoor areas with high influence of constant light by solar radiation and high temperatures. By its robust aluminum housing and the optional heating the LDM51A Lumos is prepared for safe use in harsh surrounding conditions.


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
  • Volume and area calculation
  • Diameter of steel coils
  • Distance measurement on hot glowing steel with temperatures over 1300 °C

Features

  • Contactless laser distance measurement on nearly every type of surface
  • Reliable operation in outdoor applications under high common light influence
  • Measuring even on extremely bad reflecting targets (coal, rubber, rust)
  • Riskless usage due to eye-safe visible laser beam (Laser class 2, EN 60825-1:2014)
  • 3 programmable digital output lines
  • Freely programmable and scalable analogue interface (4 ... 20 mA)
