SIStec SL3 ABB LM80 Laser Level Transmitter 30M Range 4-20mA with P801 Dust Tube
The SIStec SL3 ABB LM80 Laser Level Transmitter is a non-contact measurement solution engineered for industrial environments where dust and harsh conditions challenge conventional sensors. Designed for continuous level monitoring of solids and opaque liquids, this device maintains accuracy in applications like silo inventory management, tank level control, and bulk material handling. Its pulsed laser technology minimizes interference from airborne particles, making it particularly effective in cement plants, mining operations, and food processing facilities.

Application Scenarios
In cement production facilities, the LM80 reliably monitors clinker levels in large storage silos despite heavy dust accumulation. Mining operations use it for continuous coal pile measurement where traditional sensors struggle with falling material interference. For example, a food processing plant in Brazil successfully integrated this transmitter with their existing ABB AC800M PLC system to automate grain silo inventory tracking. The narrow beam divergence (3 mrad) allows precise measurements in tight spaces like chemical reactor vessels, while the rugged aluminum housing withstands temperature extremes from -40°C to +60°C.
Our inventory includes compatible control components like ABB’s PM866 PLC modules, 3BHB013088R0001 DCS cards, and 2711-B6C20 HMI panels for seamless system integration. We’ve also supplied this transmitter alongside GE’s VMIVME-7807 interface modules for power plant ash handling systems.
