Đặc tính kỹ thuật và thiết kế
-
Performance in High Silos: The FMP57 is the heavy-duty specialist for bulk solids, offering rope probes up to 45 meters (148 ft). The physical probe ensures that the radar pulse reaches the material surface without being scattered by the dusty atmosphere or absorbed by the geometry of a tall, narrow silo.
-
High Tensile Load Resistance: In large silos, the downward pull of moving solids can exert massive forces on a probe. The FMP57 is built to withstand these tensile loads, ensuring the rope and process connection remain intact during heavy discharge cycles.
-
Multi-Echo Tracking Evaluation: Using sophisticated software algorithms, the FMP57 filters out interference from silo internal structures, such as cross-braces or ladders. This Multi-Echo Tracking ensures the device maintains a lock on the true level signal even in vessels with complex internal geometries.
-
Heartbeat Technology: This diagnostic suite allows for continuous self-monitoring and traceable verification of the device. It can identify issues like probe abrasion or abnormal signal attenuation, enabling maintenance teams to intervene before a failure occurs.
-
Data Security (HistoROM): All device parameters and historical event logs are stored on an integrated memory module. This allows for rapid commissioning and ensures that all settings are automatically transferred if the transmitter electronics are replaced.
-
SIL3 Safety Integrity: The FMP57 is developed according to IEC 61508 for use in safety-instrumented systems. Its simplified proof-testing procedure allows for functional verification without the need to empty the silo or remove the sensor.
