Technical Characteristics and Performance
-
Immunity to Dust and Noise: In bulk solids handling, pneumatic filling often creates extreme dust and acoustic noise. Since the FMP56 guides its pulse along a physical probe, the measurement signal is unaffected by the atmosphere in the silo, providing a stable and reliable level reading where ultrasonic or non-contact radar might fail.
-
Multi-Echo Tracking Evaluation: The device utilizes advanced algorithms to distinguish between the actual material level and interference echoes caused by silo walls, internal bracing, or ladders. This ensures the sensor remains focused on the true product level even in narrow vessels with internal obstacles.
-
Rope Probe Design: The FMP56 typically utilizes a rope probe to accommodate the significant heights of storage silos (up to 12m). This design is also more resilient to the lateral forces and tensile loads often exerted by moving bulk solids compared to rigid rod probes.
-
Bluetooth Connectivity and SmartBlue App: For easier commissioning and maintenance, the FMP56 supports remote access via Bluetooth. Operators can configure the device and view diagnostic data from a safe distance using the SmartBlue app, which is particularly beneficial for sensors mounted atop tall, difficult-to-reach silos.
-
Data Integrity with HistoROM: An integrated memory module stores all device-specific parameters and event logs. If the transmitter electronics need to be replaced, the configuration can be restored instantly, minimizing downtime and the risk of setup errors.
-
Heartbeat Technology: This suite provides continuous self-monitoring and traceable verification of the device’s functionality. It can detect issues like probe wear or significant build-up, supporting predictive maintenance and ensuring long-term operational safety.
