Endress+Hauser FDU91-RG2AA Ultrasonic measurement Time-of-Flight Prosonic

Endress+Hauser FDU91-RG2AA Ultrasonic measurement Time-of-Flight Prosonic

Description:

Ultrasonic sensor for level and flow measurement for connection to FMU9x (measuring range?up to 10m)

Product name : Prosonic S FDU91

Extended order code : FDU91-RG2AA

R-Approval : Non-hazardous area

G-Process Connection : Thread ISO228 G1, PVDF

2-Cable Length:10m/32ft

A-Heater:W/o

A- Additional Option : Basic version

Shipping Weight : 2 Kg

Additional Informaiton:

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).

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)

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