Technical Characteristics and Superior Range
-
Maximum Measuring Reach: The FDU93 is engineered for scale, offering a reach of up to 25 m (85 ft) for liquids and 15 m (50 ft) for bulk materials. This makes it a preferred choice for large-scale mining operations, municipal water reservoirs, and industrial grain silos.
-
Time-of-Flight Accuracy: The distance to the product is calculated by measuring the travel time of ultrasonic pulses. To maintain precision across these long distances, the sensor features an integrated temperature sensor that compensates for variations in the speed of sound caused by environmental temperature shifts.
-
Self-Cleaning Membrane: The active vibration of the sensor face during measurement creates a self-cleaning effect. This prevents dust and moisture from accumulating on the transducer, which is critical in the dusty environments typical of long-range solids measurement.
-
Rugged Environmental Protection: With an IP 68 rating, the FDU93 is fully flood-proof and weather-resistant. Its robust construction allows it to operate in rough ambient conditions and process temperatures up to +95 °C.
-
Flexible System Architecture: The sensor is installed at the measurement point while the transmitter (FMU90/FMU95) can be located in a control room or safe area up to 300 meters away. The transmitter automatically recognizes the FDU93, significantly simplifying the commissioning process.
