Ultrasonic Measurement Time-of-Flight Prosonic FDU95
Brand: Endress+Hauser
Extended The FDU95 ultrasonic sensor is 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 buildup due to the self-cleaning effect of sensors. Suited for explosion-hazardous areas. Maximum measuring range in solids is 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.
- Process connection: Thread
- Temperature: -40 to +80°C or +150°C (-40 to +176°F or +302°F)
- Pressure: +0.7 to +1.5bar (+10 to +22psi)
- Maximum measuring range: Solids 45m (148ft)
- Blocking distance: 0.7m / 80°C (2.3ft), 0.9m / 150°C (2.9ft)
- International explosion protection certificates
- 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
