Технические характеристики и производительность
-
Extended Measuring Range: The FDU91 provides a reliable measuring range of up to 10 m in liquids and 5 m in bulk solids. This makes it ideal for medium-sized silos, wastewater basins, and large-scale industrial sumps.
-
Time-of-Flight Precision: By emitting ultrasonic pulses and measuring the return time, the sensor determines the distance to the product surface. An integrated temperature sensor provides real-time compensation for the speed of sound, ensuring accuracy even in outdoor installations with fluctuating temperatures.
-
Extreme Chemical Resistance: The sensor is hermetically welded and made of PVDF, making it highly resistant to aggressive chemicals, acidic vapors, and corrosive industrial environments.
-
Self-Cleaning Membrane: The ultrasonic transducer vibrates during operation, which creates a self-cleaning effect that prevents the accumulation of dust, moisture, or light build-up on the sensor face.
-
Robust IP 68 Protection: The FDU91 is completely flood-proof and weather-resistant. This durability allows for reliable performance in wastewater treatment plants, outdoor flumes, and heavy industrial sites.
-
Seamless Integration: The sensor is automatically detected by the Prosonic FMU90 or FMU95 transmitters, allowing for “plug-and-play” setup and simplified commissioning.

Основные приложения
-
Medium-Sized Liquid Storage: Monitoring levels in chemical tanks, oil-water separators, and wastewater wet wells.
-
Open Channel Flow: Measuring high-volume flow in large flumes and weirs for municipal water management.
-
Bulk Solid Monitoring: Level detection for sand, plastic pellets, or grain in medium-height silos or on conveyor discharge points.
-
Flood-Prone Areas: Due to its IP 68 rating, it is perfect for level monitoring in storm-water overflow basins.
