The NivoRadar NR 3300 is an advanced radar-based level measurement solution engineered for continuous monitoring of bulk solids in industrial environments. Designed to perform reliably under extreme process conditions, it delivers precise level readings even in high temperatures and dusty atmospheres. Its innovative lens antenna technology ensures focused signal transmission, making it ideal for challenging silo and storage applications.

Key Features

  • Narrow 3° beam angle for precise targeting
  • Reliable measurement in dusty and high-temperature conditions
  • Continuous level monitoring for bulk solids
  • Adjustable flange for flexible installation
  • Integrated air purge system for lens cleaning
  • High accuracy measurement performance

Application

The NR 3300 is widely used in industries handling bulk materials such as cement, grains, chemicals, minerals, and powders. It is especially effective in silos, hoppers, and storage vessels where traditional sensors struggle due to dust buildup, uneven surfaces, or extreme temperatures. It helps maintain consistent inventory levels and prevents overfilling or material shortages.

Design & Functionality

This radar sensor operates using non-contact measurement technology, ensuring minimal maintenance and long-term reliability. The lens antenna design concentrates the radar beam, allowing precise detection even in narrow or conical silo structures. The adjustable flange simplifies installation and alignment, ensuring optimal positioning for accurate readings.

Total Crossed Beams

The focused radar beam minimizes interference from internal structures, reducing signal noise and improving measurement consistency across the entire vessel.

Beam Pitch Options

The narrow beam angle ensures accurate targeting of bulk material surfaces, even in uneven or sloped conditions, enhancing measurement reliability.

Intrinsic Synchronism

The sensor maintains stable signal processing, ensuring consistent performance even under fluctuating process conditions such as dust turbulence or temperature variations.

Operational Advantages

The NR 3300 enhances operational efficiency by delivering reliable, real-time level data. Its robust design reduces maintenance needs, while the integrated cleaning system ensures uninterrupted performance in dusty environments. This results in improved process control, reduced downtime, and optimized material handling across industrial operations.
