Bruksområde
The FDU91F ultrasonic sensor for continuous, non-contact and maintenance-free level measurement of fluids, pastes, sludges and powdery to coarse bulk materials. Also for flow measurement in open channels and at weirs. Measurement is unaffected by dielectric constant, density or humidity and also unaffected by build-up due to the self-cleaning effect of sensors. Fully welded 316L with hygienic process connection available. Maximum measuring range in liquids 10m (33ft), solids 5m (16ft).
Continuous, non-contact level measurement of fluids and bulk materials in silos, on belts, stockpiles or in crushers. Also for flow measurement in open channels and at weirs. Used in measurements in low structural heights.
Process connections: Thread, Tri-Clamp
Temperature: -40 to +105°C (-40 to +221°F)
Pressure: 0.7 to 4bar (10 to 58psi)
Max. measuring range: Liquids 10m (33ft), solids 5m (16ft)
Blocking distance: 0.3m (1ft)
International explosion protection certificates, hygienic certificates
Fordeler
Integrated temperature sensor for Time-of-Flight correction. Accurate measurements are possible, even if temperature changes are present
Hermetically welded sensors (316L, 1.4404, 1.4435) 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)
Hygienic process connections available
