SITRANS LR530 is a radar level sensor for continuous measurement up to 120 m, featuring a sealed PTFE lens antenna with integrated gasket. It is ideal for corrosive liquids and hygienic applications in harsh environments.
Key Features
-
Continuous level measurement up to 120 m (393 ft) with ±1 mm accuracy (IEC 62828 compliant)
-
Fast commissioning via 4-button HMI, SITRANS mobile IQ app (Bluetooth), or SIMATIC PDM
-
Integrated graphical interface with echo profile display and backlight for on-site operation
-
Embedded IQ Guard for device health monitoring with NE107 diagnostics and quality inspection reporting
-
Advanced Process Intelligence ensures stable performance in noisy environments
-
Auto False Echo Suppression and Near Range Suppression to minimize interference from buildup or nozzle effects
-
Supports HART 7 digital communication
-
Low power consumption, with official Environmental Product Declaration (EPD)
-
Optional Second Line of Defense (SLOD) for enhanced safety in hazardous or toxic material applications
-
Built-in 100,000-point data logger for process optimization and analysis
-
Compliant with API 2350 for overfill prevention in dangerous liquid storage
Typical Applications
Designed for a wide range of industrial level measurement needs, including:
-
Liquids: chemical tanks, process vessels, water storage
-
Sludge: wastewater treatment and industrial processing
