Field of application

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
