LM80 Intermediate Range Laser Level Transmitter

Brand: ABB Group

Based on pulsed laser technology, the LM80 embodies speed and accuracy in a single, easy to use and install product.

Whether measuring a few meters into the confined space of a crusher, or to the bottom of the tallest silo, the LM80 with its laser pointer and long range is the plug-and-play solution to level measurement.

The LM80 features advanced timing and sophisticated signal processing for pinpoint accuracy at up to 100 m (330 ft.) for level applications and up to 150 m (500 ft.) for positioning applications.
Features
  • Maintenance free, non-contact continuous level sensor
  • Range up to 100 m (330 ft) for level applications
  • Range up to 150 m (500 ft) for positioning applications
  • Easy and intuitive setup
  • No calibration required
  • Continuous level monitoring for granular solid materials and opaque liquids
  • Measures solids and opaque liquids at any angle
  • Last Pulse Detection for Measurement with Light and Moderate Dust
  • Built-in laser pointer for accurate alignment in narrow or tall vessels
  • Auto-ranging to measure all levels
  • Available non condensing heated optics prevent condensation issues
  • No Beam Divergence = No False Echoes
  • Rugged and Robust Aluminum Enclosure
  • CSA, ATEX and IECEx potentially explosive atmosphere ratings
