Technical details and application highlights

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

The Vibranivo VN 1040 vibrating fork level switch is engineered for precise point level detection in dry and free-flowing bulk solids. Designed for industrial storage and processing environments, this device ensures consistent monitoring of material levels in silos, bins, and vessels. Its flexible probe extension design allows customization according to application needs, making it suitable for a wide range of industries handling powders, granules, and granular solids.

Key Features

  • Reliable vibrating fork measurement technology
  • Adjustable probe length using flexible tube extension
  • High sensitivity for low-density materials
  • Robust aluminium housing with IP66 protection
  • Wide temperature and pressure tolerance
  • Multiple output signal options for integration
  • Suitable for hazardous and regulated environments

Application

The VN 1040 is widely used in industries such as cement, food processing, chemicals, plastics, and agriculture. It is ideal for detecting full, empty, or demand levels in silos and vessels containing dry bulk materials like powders, grains, pellets, and granules. It helps prevent overflow conditions and ensures uninterrupted material flow.

Design & Functionality

This vibrating fork sensor operates on vibration-based detection, where the fork oscillates at a specific frequency. When bulk material comes into contact with the fork, the vibration changes, triggering a switching signal. The device supports both top and horizontal mounting positions, providing flexibility in installation.

Total Crossed Beams

The VN 1040 utilizes a robust fork structure designed to withstand mechanical stress and continuous operation in industrial environments, ensuring long-term reliability.

Beam Pitch Options

The adaptable probe extension system allows users to define the required immersion length using flexible tube extensions, available up to 4 meters. This enables precise positioning for accurate level detection.

Intrinsic Synchronism

The sensor maintains stable vibration frequency and consistent switching performance, ensuring reliable detection regardless of environmental variations or material properties.

Operational Advantages

  • Prevents overfilling and material loss
  • Reduces downtime and maintenance costs
  • Improves process efficiency and safety
  • Suitable for low-density bulk materials
  • Easy installation with customizable probe length
