Karakteristik Teknis dan Desain
-
Extended 30m Measuring Range: The FMR20B provides the power needed for larger storage tanks, tall silos, and deep lift stations. Its 80 GHz technology maintains a narrow beam angle across this entire range, preventing interference from narrow vessel walls or internal obstructions.
-
Heartbeat Technology: A significant upgrade for the basic segment, Heartbeat Technology enables on-demand device verification and advanced diagnostics. Operators can verify the sensor’s accuracy and health according to quality standards without interrupting the process, significantly reducing maintenance downtime.
-
Bluetooth Remote Access: With an encrypted Bluetooth connection, the device can be configured and monitored from a smartphone or tablet via the SmartBlue app. This is particularly valuable for sensors installed in hazardous areas or hard-to-reach locations like sewer shafts or atop tall silos.
-
It’s Me-Function: To ensure the correct device is being configured in a plant with multiple sensors, the “It’s me-function” triggers a flashing LED on the connected device. The integrated LED also provides immediate visual feedback on the device status (e.g., normal operation, maintenance required, or error).
-
Guided Setup Wizards: Complexity is minimized through step-by-step setup sequences. These wizards guide the user through commissioning and even the Heartbeat verification process, ensuring high-quality installation without the need for extensive manual study.
-
Versatile Solids and Liquids Handling: Beyond standard liquids, the FMR20B is capable of measuring powdery and granular bulk solids, even in pneumatic conveying systems where dust and air movement are present.
