XLR30 – Laser sensors with long measurement range

XLR 30 is a laser based sensor that has a long measurement range, >30m, with mm-accuracy. It can be used for level measurement in silos, mat height before presses, head control/slurry height in gypsum line mixers and positioning applications e. g. of carriers, cranes and panels.

The sensor has a high protection class (IP65) for use in tough environments, is easy to install and comes with various data interfaces for easy connection to different production control systems. It has a 4-20mA scalable analog output and digital alarm output signals, easily configurated using the PC setup and display software, included in delivery.

Operating Principle
XLR 30 is a laser based sensor working with phase shift technology. This means that the measurement accuracy is the same regardless of measurement distance.
