Field of application Ultrasonic measurement Time-of-Flight Prosonic FDU95

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).

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.

Benefits Ultrasonic measurement Time-of-Flight Prosonic FDU95

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)

Integrated heating against a build-up of ice at the sensor (optional) ensures reliable measurement
