Product Description
Comprehensive Technical Overview: Siemens SITRANS LR200 Radar Level Transmitter
1. Product Introduction
The SITRANS LR200 is a 2-wire, 6 GHz pulse radar transmitter designed for continuous level monitoring of liquids and slurries in storage and process vessels. It operates effectively at ranges up to 20 m (66 ft) and withstands extreme conditions, including high temperatures (up to 200°C) and pressures (up to 0.5 bar g) . Engineered for reliability in demanding industrial environments, it integrates advanced signal processing and user-centric design features. Key models include:
7ML5422: Polypropylene rod antenna (standard).
7ML5425: Horn antenna variant.
7ML5423: Rod antenna for specialized applications

3. Key Design Innovations
(a) Uni-Construction Antenna Technology
Constructed from chemically resistant polypropylene, hermetically sealed to prevent corrosion.
Integrated internal shield eliminates interference from vessel nozzles or obstructions .
(b) Rotatable Electronics Head
Allows ±340° rotation for easy alignment with conduit/wiring and optimal viewing angles.
Simplifies installation in confined spaces .
(c) Process Intelligence® Signal Processing
Patented algorithm enhances reliability by suppressing false echoes (e.g., agitators, ladders).
Adaptive to vapor, foam, and turbulent surfaces .
(d) Intrinsic Safety Compliance
Programming without opening the enclosure via infrared handheld programmer (IS-certified).
Reduces downtime in hazardous areas (ATEX/IECEx zones) .
4. User Interface & Configuration
Local User Interface (LUI)
Alphanumeric display supporting four languages (English, German, French, Spanish).
Graphical echo profiles for real-time diagnostics and troubleshooting .
Quick Start Wizard
Requires only two parameters (tank height, empty calibration) for basic operation.
Plug-and-play setup reduces commissioning time .
Remote Configuration Options
SIMATIC PDM or HART communicator for advanced parameterization.
Infrared handheld programmer (sold separately, e.g., 7ML5425-0DA20-2DA1) .
5. Application Versatility
The LR200 excels in challenging scenarios:
High-temperature liquids: Asphalt, hot oil (up to 200°C).
Vaporous environments: Condensate vessels, digesters.
Agitated vessels: Internal shield mitigates false echoes from mixers.
Corrosive media: Polypropylene antenna resists acids, alkalis, and slurries .
6. Installation and Maintenance
Mounting
Universal flat-faced flange compatible with ANSI/DIN/JIS 4" (100 mm) flanges.
Integrated aimer for precise antenna alignment .
Maintenance
Hermetic sealing prevents ingress; no routine recalibration needed.
Self-diagnostic functions alert to antenna buildup or signal loss
