High-Reliability Level Measurement: Endress+Hauser Prosonic FDU90 Ultrasonic Sensor

Key Benefits for Industrial Procurement
  • Zero Contact, Zero Maintenance
    The non-contact ultrasonic principle means no physical interaction with the medium. This eliminates coating issues, sensor fouling, and mechanical wear, leading to lower total cost of ownership (TCO).
  • Integrated Temperature Compensation
    The FDU90 features a built-in temperature sensor to measure the ambient air temperature. This allows the connected FMU90 transmitter to dynamically calibrate the sound velocity, ensuring accurate readings even with temperature fluctuations.
  • Self-Cleaning Sensor Face
    The advanced sensor face design minimizes condensation buildup and dust accumulation. The automatic acoustic self-cleaning effect ensures continuous, uninterrupted signal transmission.
  • Global Safety Certifications
    Available with extensive international explosion-protection certificates, including ATEX, FM, CSA, and IECEx, ensuring total compliance in hazardous areas.

Introduction
In demanding industrial processing, choosing a robust and wear-free sensor is critical to ensuring smooth automation. The Endress+Hauser Prosonic FDU90 Ultrasonic Sensor is a globally trusted solution for non-contact, continuous level measurement. Designed for both liquids and bulk solids, the FDU90 excels in challenging environments where contact-based measurement fails due to corrosion, clogging, or mechanical wear.
As an experienced industrial automation distributor, we provide 100% original, brand-new E+H FDU90 sensors with full factory certification. Whether you need to replace an existing field unit or source components for a new engineering project, we offer competitive B2B wholesale pricing and rapid global logistics.
Core Specifications & Operating Limits
The Prosonic FDU90 is engineered to operate seamlessly with the Prosonic S FMU90 transmitter, forming a highly advanced time-of-flight (ToF) measurement system.
  • Maximum Measuring Range: Up to 5 meters (16 ft) for liquids; up to 2 meters (6.5 ft) for bulk solids.
  • Blocking Distance: Ultra-short blocking distance of just 0.07 meters (0.23 ft), maximizing the usable volume in small tanks.
  • Process Connection: G 1″ or NPT 1″ thread, ceiling mounting, or slip-on flange options.
  • Operating Temperature: -40°C to +80°C (-40°F to +176°F).
  • Process Pressure: 0.7 bar to 4 bar (10 psi to 58 psi) absolute pressure.
  • Ingress Protection: IP68 rated (fully weatherproof and submersible), making it impervious to flooding.

 

Typical Application Scenarios
  • Water & Wastewater Treatment: Perfect for open-channel flow measurement in flumes and weirs, sewage pump control, grate/screen differential control, and sludge tank level tracking.
  • Chemical & Process Tanks: Ideal for aggressive acids, alkalis, and chemical additives where contact-less, corrosion-resistant measurement is mandatory.
  • Small Bulk Material Hoppers: Reliable level monitoring for powders, plastic granules, grains, and aggregates in small silos or conveyor transfer points.
Why Source E+H FDU90 From Us?
  • 100% Authenticity & Serial Tracking: Every FDU90 sensor we supply features an original Endress+Hauser serial number. You can verify the data sheet, manufacturing date, and authenticity directly with E+H.
  • Extremely Competitive Pricing: Our strong supply chain allows us to pass significant volume discounts directly to overseas engineering firms, system integrators, and B2B wholesalers.
  • Ready Stock & Fast Dispatch: We maintain stock of the most popular FDU90 configuration variations, drastically reducing your project lead times compared to standard factory production waiting periods.
  • Heavy-Duty Export Packaging: All instruments are packed with multi-layer anti-vibration foam and rigid export cartons to ensure safe arrival via DHL, FedEx, UPS, or sea freight.
