The ABB LM200 is a long-range laser level transmitter that calculates distance using laser pulse time-of-flight technology. It is suitable for continuous measurement of bulk solids and opaque liquids, as well as distance and position monitoring of moving equipment. Its narrow beam helps target surfaces in tall vessels and areas with internal structures.

Key Features

  • Non-contact, continuous level measurement
  • Measuring range up to 190 m for level applications and 400 m for positioning
  • Narrow laser beam with a visible aiming laser for alignment
  • Automatic ranging and no routine calibration requirement
  • Last Pulse Detection for light to moderate dust conditions
  • Optional heated optics to help prevent condensation
  • 4–20 mA analog output and relay output
  • Rugged aluminum enclosure; CSA, ATEX and IECEx ratings available depending on configuration

Applications

Suitable for silos, storage tanks, hoppers, bunkers, feed chutes, and crushers handling grain, coffee, coal, plastic pellets, mineral ores, powders, and other bulk solids. It can also measure opaque liquids and monitor the position of tripper cars, stackers, reclaimers, and cranes.
