Ultrasonic measurement Time-of-Flight Prosonic FDU95

Field of Application :

The FDU95 ultrasonic sensor is designed for continuous, non-contact, and maintenance-free level measurement of bulk materials, from powdery to coarse textures. The sensor operates reliably without being affected by dielectric constant, density, or humidity. Its self-cleaning effect prevents material build-up, ensuring long-term accuracy. It is well-suited for explosion-hazardous areas.

This sensor is ideal for:

• Bulk material level measurement in silos, stockpiles, crushers, and conveyor belts
• Low structural height applications
• Harsh industrial environments, including explosion-hazardous zones
