Description
Endress+Hauser FDU95: Advanced Ultrasonic Bulk Measurement
The Endress+Hauser FDU95: advanced ultrasonic bulk measurement device is specifically engineered for continuous, non-contact, and maintenance-free level monitoring of powdery to coarse bulk materials. This highly accurate sensor operates independently of the material’s dielectric constant, density, or humidity, ensuring reliable performance across a wide range of applications. A key benefit is its inherent self-cleaning effect, which significantly reduces material build-up on the sensor surface, thereby minimizing maintenance requirements and ensuring consistent, dependable readings. The FDU95 is also designed for safe operation in explosion-hazardous areas, providing a secure and efficient solution for challenging industrial environments.
Versatile Silo and Stockpile Bulk Material Monitoring
This sophisticated FDU95 sensor excels in versatile silo and stockpile bulk material monitoring, offering precise level detection for various materials, from fine powders to coarse aggregates. It is ideal for installations in silos, on conveyor belts, within stockpiles, and even in crushers, particularly where structural height is limited. The non-contact measurement principle ensures that the sensor remains free from wear and tear, and the self-cleaning feature actively combats adhesion of sticky or dusty materials. This robust functionality guarantees accurate inventory management and efficient process control, making the FDU95 a cornerstone for reliable bulk material handling operations.
Precise Flow Measurement In Open Channels
The Endress+Hauser FDU95 provides precise flow measurement in open channels, a critical function for effective water resource management, wastewater treatment, and industrial process control. Utilizing ultrasonic technology, it offers a non-contact method to accurately determine flow rates by measuring the material’s level. This eliminates the need for mechanical components that can wear out or become clogged, thus reducing maintenance and ensuring sustained accuracy. Its ability to function reliably in challenging environmental conditions, coupled with its weather-resistant and flood-proof design (IP 68), makes the FDU95 an outstanding choice for monitoring water bodies and industrial effluents.
Robust Sensor Design For Harsh Ambient Conditions
Engineered for robust sensor design for harsh ambient conditions, the FDU95 offers a separated installation option. This allows the sensor unit to be physically separated from the transmitter by up to 300 meters. This separation is highly advantageous, as it permits the sensitive transmitter electronics to be housed in a more controlled environment, such as a field housing or a top-hat rail enclosure within a control cabinet. This configuration protects the transmitter from extreme temperatures, corrosive atmospheres, dust, or excessive vibration, thereby enhancing the overall reliability and lifespan of the measurement system, especially in demanding industrial settings.
Seamless Operation In Explosion Hazardous Areas
The FDU95 guarantees seamless operation in explosion hazardous areas with its comprehensive suite of international explosion protection certificates. These include critical certifications such as ATEX, FM, CSA, IEC Ex, INMETRO, NEPSI, and UK Ex, ensuring the sensor meets the highest safety standards for use in environments where flammable gases or combustible dusts may be present. Its intrinsically safe design prevents the possibility of ignition, providing a secure solution for level measurement in potentially explosive atmospheres. This adherence to rigorous safety protocols underscores the FDU95’s suitability for high-risk applications, ensuring operational safety and compliance.

Extended Maximum Measurement Solids Range
The FDU95 boasts an extended maximum measurement solids range of up to 45 meters (148 feet). This impressive capability allows for precise level monitoring in very tall silos, large storage facilities, or extensive stockpiles, catering to a wide array of bulk material handling requirements. The sensor’s non-contact ultrasonic technology ensures that this extended range is achieved with high accuracy, unaffected by the material’s properties or environmental conditions. This robust performance makes the FDU95 an ideal solution for managing large inventories and optimizing operations in industries dealing with significant volumes of bulk materials.
Intelligent Features Enhance Measurement Accuracy
The FDU95 is packed with intelligent features that enhance measurement accuracy, including an integrated temperature sensor that enables precise Time-of-Flight correction. This critical compensation mechanism ensures that temperature variations do not affect the accuracy of the level readings, providing reliable data even in environments with fluctuating temperatures. Furthermore, the sensor’s integrated automatic detection simplifies commissioning when paired with FMU90 or FMU95 transmitters, reducing setup time and potential errors. Its weather-resistant and flood-proof IP 68 rating ensures durability and reliable performance in diverse and demanding ambient conditions, minimizing service needs.
