Description
ABB LM80 Laser Level Transmitter Product Documentation
The
ABB LM80 is a high-performance
laser level transmitter designed for non-contact measurement of granular solids and opaque liquids in industrial and utility applications. Built on pulsed laser technology, the
LM80 delivers accurate level, distance, and position measurements up to
100 meters (330 ft) for level applications and
150 meters (500 ft) for positioning. Its robust design and advanced signal processing make it ideal for extreme environments, including dusty, high-temperature, or corrosive conditions. The
LM80 supports seamless integration with process control systems via
4-20 mA analog output and
HART protocol, ensuring compatibility with legacy and modern automation setups.

ABB LM80
The ABB LM80 excels in:
- Power Generation: Monitoring coal silos and ash bunkers.
- Mining & Minerals: Measuring ore stockpiles and conveyor belts.
- Food & Beverage: Tracking grain, flour, or sugar in silos.
- Chemical & Petrochemical: Monitoring bulk solids and opaque liquids.
Case Study:
A European cement plant deployed the LM80 to measure limestone in a 50-meter silo with moderate dust. The HART protocol enabled real-time data integration with the plant’s DCS, while the heated optics prevented condensation during temperature fluctuations. The system reduced manual inspections by 80% and improved inventory accuracy by 95%.

ABB LM80
- Environment: Choose the LM80 for dusty, humid, or high-temperature environments.
- Integration: Opt for the HART version if compatibility with existing automation systems is critical.
- Safety: Select models with ATEX/IECEx certifications for hazardous areas.
- Mounting: Use ANSI/DIN flanges or tri-clover fittings for secure installation.
- Alignment: Use the built-in laser pointer to aim the sensor directly at the material surface.
- Calibration: Perform periodic checks using the HART protocol or ABB’s LCD2 handheld configurator.
- Safety: Power off the system before cleaning or replacing components.
