LDM51 Lumos Laser Distance Measurement

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 500 m. Due to the high measuring frequency of 100 Hz also fast movements of the target can be captured.

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 LDM51 Lumos is prepared for safe use in harsh surrounding conditions.
