Description
ABB LC300S/SP11: Product Overview
The ABB LC300S/SP11 is a high-precision level controller/transmitter designed for industrial process automation, focusing on liquid level measurement in tanks, vessels, and open channels. As part of ABB’s LC Series, it addresses the need for reliable, accurate, and durable level monitoring in harsh environments (e.g., chemical plants, water treatment facilities, oil/gas terminals).
The device supports multiple measurement principles (configurable per model variant SP11), including non-contact radar/ultrasonic (for corrosive or sticky liquids) and submersible hydrostatic (for deep tanks or underground storage). It outputs a continuous 4-20mA analog signal (standard) or digital HART protocol, enabling seamless integration with ABB’s AC500 PLC, DCS systems, or third-party control platforms.
Engineered for industrial robustness, the LC300S/SP11 features a rugged housing (stainless steel or PVDF, depending on variant) and wide operating temperature range (-40°C to +85°C), making it suitable for outdoor or unconditioned environments. Its compact design simplifies installation, while built-in diagnostics (e.g., signal strength monitoring, fault alerts) reduce maintenance effort.

Core Features & Customer Value
-
High Accuracy & Stability: ±0.5% FS accuracy ensures reliable level readings, critical for inventory management (e.g., chemical storage) and process control (e.g., avoiding tank overflow/run-dry).
-
Flexible Measurement Principles: Non-contact radar/ultrasonic variants eliminate direct contact with corrosive/sticky liquids, reducing maintenance; submersible hydrostatic variants suit deep tanks or sludge applications.
-
Robust Design: IP67/IP68 protection and wide temperature range (-40°C to +85°C) enable deployment in harsh environments (e.g., outdoor oil tanks, chemical plants with steam).
-
Easy Integration: 4-20mA/HART output works with ABB AC500 PLC, DCS, or third-party systems; HART protocol allows remote configuration and diagnostics.
-
Low Maintenance: Self-diagnostics (signal strength, sensor fouling alerts) and non-contact options minimize cleaning/replacement needs.
