With ETFE or PVDF transducers for chemical compatibility and IP66/IP68 protection,

  SITRANS LR100 Radar Level Transmitter 

Key Advantages:
• High accuracy: ±5 mm measurement precision
• Loop powered: 4–20 mA, 2-wire transmitter for easy integration
• Bluetooth configuration: Quick setup via SITRANS mobile IQ smartphone app
• Rugged design: Chemically resistant PVDF enclosure with IP66/IP68 protection
• Flexible installation: Can measure through plastic tank tops and in open-air applications
This makes the LR100 an ideal solution for chemical tanks, water & wastewater treatment units, small process vessels, and slurry storage systems 

Accurate level measurement becomes critical in large storage tanks, chemical vessels, and bulk material silos, especially where dust, vapors, or internal obstructions can affect measurement reliability.

The Siemens SITRANS LR530 Radar Level Transmitter delivers high-precision, non-contact level measurement using advanced 80 GHz FMCW radar technology, enabling reliable monitoring of liquids and solids over long measuring distances.

With a very narrow beam angle (as low as 3°) and measurement range up to 30 m, the LR1530 can accurately focus on the product surface while minimizing interference from tank internals.

Product Overview
The LSVR is a vibrating rod point level switch designed for solids and powders. It is widely used across industries such as cement, PVC, coal, steel, food grains, fly ash, and chemicals. The device is a single-element, mechanically tuned sensor that provides reliable level detection without requiring calibration.

Operating Principle

• A piezoelectric crystal excites the vibrating rod at its natural resonance.
   
• In free air, the rod vibrates at full amplitude.
   
• When in contact with bulk material, resonance is disturbed, causing amplitude drop.
   
• The electronics detect this change, triggering a switching output to indicate material presence.
   

✅ In short: The Trumen LSVR is a rugged, reliable, and calibration-free vibrating rod switch for bulk solid level detection, offering wide industry applicability, high safety certifications, and flexible mounting/electrical options, making it a strong solution for demanding process environments.
