Endress Hauser Prosonic FDU91 Ultrasonic Level Sensor ATEX Certified

The FDU91 ultrasonic sensor provides 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 measuring weirs. The measurement is unaffected by dielectric constant, density or humidity and also unaffected by build-up due to the self-cleaning effect of sensors. Designed for explosion hazardous areas with maximum measuring range of 10m (33ft) for liquids and 5m (16ft) for solids.

Typical applications include:

• Continuous level measurement in silos, on belts, stockpiles and in crushers
• Flow measurement in open channels and at weirs
• Measurements in low structural heights

• Integrated temperature sensor for Time-of-Flight correction ensures accurate measurements even with temperature changes
• Hermetically welded PVDF sensor for highest chemical resistance
• Separate installation from transmitter (up to 300m) for rough ambient conditions
• Reduced build-up formation due to self-cleaning effect
• Integrated automatic sensor detection for simple commissioning
• Weather resistant and flood-proof (IP 68)
• Optional integrated heating prevents ice build-up on sensor
