ABB LM80 SL3 Laser Level Transmitter

The LM80 SL3 from ABB delivers non-contact level measurement for challenging industrial environments. This 30-meter range device with 4-20mA output specializes in maintaining accuracy where dust and interference would disrupt conventional sensors. We’ve seen it perform reliably in cement plants and bulk material handling facilities where optical clarity becomes problematic.

Real-World Applications

Engineers frequently specify this transmitter for dusty environments like mineral processing plants where traditional ultrasonic sensors fail. The integrated P801 dust tube proves particularly valuable in cement storage facilities where airborne particles would otherwise obstruct measurements. We’ve successfully deployed these units in:

• Coal-fired power plant ash silos
• Food processing grain storage tanks
• Chemical production reaction vessels
• Water treatment sludge thickening basins

Compatible with major DCS systems through its standard 4-20mA interface, this device works seamlessly with ABB’s AC10272001R0101 signal converters and PM866 controllers.
