  • Robust construction with high mechanical load resistance
  • Suitable for harsh industrial conditions with IP66 protection

Application

This capacitive level sensor is widely used in industries handling bulk solids such as cement, food processing, chemicals, and agriculture. It is ideal for detecting full levels in silos, hoppers, and storage vessels. The adjustable probe length allows precise positioning, ensuring accurate detection even in tall or irregular containers.

Design & Functionality

The CN 4050 operates on a capacitive measurement principle, detecting changes in capacitance when material comes into contact with the probe. Its cable extension design allows flexible installation, while the robust structure ensures durability under lateral forces. The sensor offers reliable switching output through relay or transistor signals, ensuring seamless integration into industrial control systems.

Total Crossed Beams

The sensor’s flexible cable probe ensures stable performance even in dynamic environments where material flow or movement may impact measurement consistency.

Beam Pitch Options

The adjustable probe length enables users to position the switching point precisely, improving accuracy in different vessel sizes and configurations.

Intrinsic Synchronism

The sensor provides consistent detection performance without signal interference, ensuring reliable operation across varying material densities.

Operational Advantages

The Capanivo® CN 4050 enhances process efficiency by preventing overfilling and ensuring accurate level detection. Its adaptability reduces installation constraints, while its robust design minimizes maintenance needs. This results in improved safety, reduced downtime, and optimized material handling operations.
