Field of application

The FDU92 ultrasonic sensor for continuous, non-contact and maintenance-free level measurement of fluids, pastes, sludges and powdery to coarse bulk materials. But also 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. Suited for explosion hazardous areas. Maximum measuring range in liquids 20m (65ft), solids 10m (33ft).

Sensor for continuous, non-contact level measurement of fluids and bulk materials in silos, on belts, stockpiles and in crushers. Also for flow measurement in open channels and at weirs. Typically used in measurements in low structural heights.

  • Process connection: Thread

  • Temperature: -40 to +95°C (-40 to +203°F)

  • Pressure: +0.7 to +4bar (+10 to +58psi)

  • Maximum measuring range: Liquids 20m (65ft), solids 10m (33ft)

  • Blocking distance: 0.4m (1.3ft)

  • International explosion protection certificates

Benefits

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

  • Hermetically welded PVDF sensor for highest chemical resistance

  • 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)

  • International Dust-Ex and Gas-Ex certificates available
