Ultrasonic measurement
Time-of-Flight
Prosonic FDU95

Ultrasonic sensor for level measurement for connection to FMU9x (measuring range up to 45m)

  • Prosonic FDU95 ©Endress+Hauser
  • Time-of-Flight measuring principle

The FDU95 ultrasonic sensor for continuous, non-contact and maintenance-free level measurement of powdery to coarse bulk materials. The measurement is unaffected by dielectric constant, density or humidity and also unaffected by build-up due to the self-cleaning effect of sensors. Suited for explosion hazardous areas. Maximum measuring range in solids 45m (148ft).

Benefits

  • Integrated temperature sensor for Time-of-Flight correction. Accurate measurements are possible, even if temperature changes are present

  • Suited for rough ambient conditions thanks to separate installation from the transmitter
    (up to 300m)

  • Reduced build-up formation because of the self-cleaning effect

  • Integrated automatic sensor detection for transmitters FMU90/FMU95 for simple commissioning

  • Weather resistant and flood-proof (IP 68)

  • Non-contact measurement method minimizes service requirements

  • International Dust-Ex and Gas-Ex certificates available

Field of application

Sensor for continuous, non-contact level measurement of bulk materials in silos, on belts, stockpiles and in crushers. Typically used in measurements in low structural heights.

  • Process connection: Thread

  • Temperature: -40 to +80°C or +150°C (-40 to +176°F or +302°F)

  • Pressure: +0.7 to +1.5bar (+10 to +22psi)

  • Maximum measuring range: Solids 45m (148ft)

  • Blocking distance: 0.7m / 80°C (2.3ft), 0.9m / 150°C (2.9ft)

  • International explosion protection certificates
