Main wetted parts PVDF (fully welded IP68 / NEMA 6P)

应用领域

The FDU91 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 10m (33ft), solids 5m (16ft).

好处

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
