คุณลักษณะทางเทคนิคและประสิทธิภาพ
-
High-Frequency 80 GHz Technology: The narrow beam focusing (as small as 3° depending on the antenna) allows the FMR60B to be installed in narrow nozzles and prevents the signal from reflecting off tank walls, baffles, or heating coils. This ensures a reliable level signal even in vessels with complex internal fittings.
-
Advanced Heartbeat Technology: Beyond basic diagnostics, Heartbeat Technology provides continuous process monitoring and on-demand verification. It can identify process anomalies, such as build-up or foam formation, and allows for documented verification of the device’s functionality without stopping the process.
-
Guided Operating Wizards: To simplify the entire lifecycle of the device, the FMR60B includes built-in wizards for commissioning, SIL-locking, and proof testing. These step-by-step guides reduce human error and ensure that safety-relevant parameters are set correctly.
-
Safety by Design: Developed according to IEC 61508, the FMR60B meets the highest safety standards for use in SIL2 and SIL3 (with homogeneous redundancy) applications. The device display even shows recommended actions during troubleshooting, speeding up recovery times.
-
Precision and Calibration: With an accuracy of ±1 mm, the FMR60B is suitable for inventory control. Each device can be supplied with a 5-point or 10-point factory calibration certificate to ensure traceability and compliance with quality management systems.
-
Versatile Installation: Despite its high precision, the device is robust enough for temperatures up to 200 °C and pressures up to 20 bar, supporting a wide variety of liquid applications from simple storage to complex process tanks.

การใช้งานหลัก
-
Process Tanks with Obstructions: Ideal for vessels containing agitators, baffles, or cooling coils where a focused beam is necessary to avoid false echoes.
-
Small Process Connections: The high frequency allows for high performance even when using 1-inch or 1.5-inch nozzles.
-
Inventory Management: Precise level tracking for high-value liquids in storage tanks where ±1 mm accuracy is required for custody transfer or mass balancing.
-
Corrosive and Aggressive Media: Suitable for a variety of chemicals due to the available range of antenna materials and process connections.
-
SIL-Rated Safety Loops: Used as a high-level alarm or continuous level monitor in safety-instrumented systems to prevent overfills.
