Application

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.
* 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

Benefits

* 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
