Product Overview:
The ABB LM80.A is a high-performance laser level transmitter engineered for continuous, non-contact measurement in demanding industrial environments where precision and repeatability are required. ABB LM80.A employs pulsed laser time-of-flight technology combined with a narrow optical beam to concentrate measurements on specific targets inside silos, tanks and vessels, thereby reducing false echoes caused by internal structures, ladders, or agitators. The device is optimized for both granular solids and opaque liquids and provides rapid update rates and stable distance readings suitable for inventory control, batch management and safety interlocks. In ABB’s product family, ABB LM80.A complements radar and ultrasonic sensors by offering a targeted optical solution when beam focus and fine angular resolution are essential. Configurable outputs, rugged housings and options for hazardous-area approvals make ABB LM80.A a practical spare and replacement option for plants upgrading instrumentation or maintaining legacy systems. Field setup is streamlined by alignment aids and accessible configuration interfaces, minimizing commissioning time and reducing the need for frequent recalibration.

Main features and advantages:
ABB LM80.A provides high target discrimination by combining a focused laser beam with precise time-of-flight measurement, which reduces multiple-echo issues and improves accuracy on uneven solids or foamy liquid surfaces. This optical precision enables ABB LM80.A to deliver repeatable readings in dusty atmospheres, supporting reliable inventory control and process regulation. The transmitter’s signal processing highlights valid echoes while suppressing spurious returns, which reduces false alarms and minimizes operator intervention. ABB LM80.A supports industry-standard outputs such as 4–20 mA and relay alarms for direct integration into PLC and DCS loops; RS-232 and optional Modbus enable configuration and diagnostics during commissioning and service.

Application fields:
ABB LM80.A is suitable across a wide range of industries that require accurate non-contact level and distance measurement. In bulk materials handling sectors such as cement, aggregates and mining, ABB LM80.A monitors solids in silos and hoppers to prevent overfill, optimize batch feeds and control reclaim processes. In water and wastewater treatment, the transmitter measures sludge and settled solids where opaque layers confound contact probes and ultrasonic sensors. In biomass and power generation facilities, ABB LM80.A provides consistent level data in dusty feedstock bunkers, supporting automated fuel handling. Chemical and petrochemical plants deploy ABB LM80.A in hazardous-area storage and processing vessels where narrow-beam discrimination avoids false readings from internal scaffolding. ABB LM80.A is also used in manufacturing and material-handling contexts for positioning tasks such as crane height sensing and conveyor alignment, where its rapid response and targeted beam enhance automation precision. By addressing narrow sightlines, internal obstructions and abrasive atmospheres, ABB LM80.A supports reliable process control and inventory management across diverse operational environments.
