Technical details and application highlights

Review the complete description, feature set, and specification details before sending your inquiry.

The Mononivo MN 4030 vibration rod is engineered for accurate and dependable point level measurement in bulk solids handling systems. Designed for industrial storage and process vessels, this device ensures reliable detection of full, empty, or demand levels. Its adaptable probe length and rugged construction make it suitable for a wide range of material types, including powders, granules, and coarse solids.

Key Features

  • Adjustable probe length up to 4 meters for flexible installation
  • Robust stainless steel construction for harsh environments
  • High sensitivity detection for low-density materials
  • Fail-safe switching logic for enhanced safety
  • Compact housing with strong ingress protection

Application

The MN 4030 is widely used in industries such as cement, food processing, chemicals, plastics, and mining. It is ideal for silos, hoppers, bins, and process vessels where accurate level monitoring is critical. It helps prevent overflow, material shortage, and process interruptions by delivering consistent switching performance.

Design & Functionality

This vibration rod operates on a vibration-based measurement principle. When the probe comes into contact with bulk material, the vibration frequency changes, triggering a switching signal. The sliding sleeve design allows variable immersion depth, ensuring precise positioning of the detection point.

Total Crossed Beams

The sensor structure ensures stable vibration transmission across the rod, enabling consistent detection even in uneven material distribution. This improves measurement reliability in dynamic bulk solid environments.

Beam Pitch Options

The flexible probe extension allows optimized positioning within vessels of varying sizes. This ensures accurate detection regardless of installation angle or mounting configuration.

Intrinsic Synchronism

The vibration system is internally synchronized to maintain stable oscillation, minimizing false triggering caused by external disturbances or material inconsistencies.

Operational Advantages

  • Prevents costly overflow and downtime
  • Reduces maintenance with durable design
  • Ensures reliable operation in aggressive conditions
  • Suitable for both light and heavy bulk materials
  • Enhances process efficiency and safety
