  • Process temperature -40 °C … 95 °C (-40 °F … 203 °F)
  • Process pressure / max. overpressure limit 0.7 bar … 4 bar abs (10 psi … 58 psi)
  • Max. measurement distance Liquids: 20 m (65 ft), Solids: 10 m (33 ft)
  • Main wetted parts PVDF (fully welded IP68 / NEMA 6P)

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

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
