Ultrasonic measurement Time-of-Flight Prosonic FDU92
Field of Application :
The FDU92 ultrasonic sensor is designed for continuous, non-contact, and maintenance-free level measurement of fluids, pastes, sludges, and powdery to coarse bulk materials. It is also suitable for flow measurement in open channels and weirs. The sensor provides highly reliable measurements that are unaffected by dielectric constant, density, or humidity. Additionally, the self-cleaning effect prevents material build-up, ensuring long-term performance.
This sensor is ideal for:
- Bulk material level measurement in silos, stockpiles, crushers, and on conveyor belts
- Flow measurement in open channels and at weirs
- Low structural height applications
- Explosion hazardous areas, certified for safe operation
