Technical Characteristics and Enhanced Safety
-
Dual Containment Design: For processes involving hazardous or high-pressure media, the FMR51 features a double ceramic coupling and a gas-tight feedthrough (second line of defense). This ensures that even in the unlikely event of a primary seal failure, the process remains contained within the vessel.
-
Extreme Temperature and Pressure: The device is built to handle the most demanding environments, operating in temperatures from cryogenic levels (-196 °C) up to +450 °C, and pressures as high as 160 bar.
-
Multi-Echo Tracking Evaluation: Advanced software algorithms allow the FMR51 to filter out interference from internal tank structures such as heating coils, baffles, or agitators. This ensures a stable and accurate level signal even in turbulent or cluttered vessels.
-
Heartbeat Technology: This diagnostic suite provides continuous monitoring of the device’s health and the process conditions. It allows for traceable verification of the radar’s performance on-demand without interrupting the process, significantly reducing the cost of manual maintenance.
-
Bluetooth Connectivity: With the SmartBlue app, operators can securely access the device from up to 25 meters away. This allows for commissioning, troubleshooting, and data visualization in hazardous areas or hard-to-reach locations without the need for a physical connection.
-
HistoROM Data Management: All configuration parameters and event logs are stored on an integrated memory module. This facilitates rapid commissioning and ensures that device settings are automatically restored if the electronics are ever replaced.
