Ultrasonic measurement Time-of-Flight Prosonic FDU91F
Field of Application :
The FDU91F 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 measurement remains unaffected by dielectric constant, density, or humidity and benefits from a self-cleaning effect that prevents build-up.
This sensor is particularly suited for:
- Silos, belts, stockpiles, and crushers for bulk material level measurement
- Open channels and weirs for flow measurement
- Low structural height applications requiring compact sensing
- Hygienic applications with its fully welded 316L stainless steel design
- Explosion hazardous areas, ensuring safe operation
Key Specifications :
- Process connections: Thread, Tri-Clamp (hygienic)
- Temperature range: -40 to +105°C (-40 to +221°F)
- Pressure range: 0.7 to 4 bar (10 to 58 psi)
