คุณลักษณะทางเทคนิคและการออกแบบ
-
80 GHz W-Band Technology: The high frequency allows for a very tight beam focus. This enables the radar to navigate through narrow nozzles and bypass internal fittings like agitators or heating coils without generating false echoes, which is a significant advantage over lower-frequency radars.
-
Innovative Drip-Off Antenna: The antenna is constructed from PTFE and features a specialized drip-off design. This prevents the accumulation of condensate or product buildup on the antenna face, ensuring maximum signal availability and reducing maintenance requirements in humid or steamy environments.
-
Heartbeat Technology: This smart sensor functionality provides continuous self-monitoring and on-demand verification. It allows for a documented “health check” of the device without process interruption, identifying anomalies before they lead to failure.
-
Safety by Design: As the first 80 GHz radar developed for SIL3 applications (in homogeneous redundancy), the FMR60 offers the highest level of functional safety. It includes a simplified proof test concept for SIL and WHG, significantly saving time during mandatory safety inspections.
-
Multi-Echo Tracking: Improved algorithms and evaluation software allow the FMR60 to track the true level echo with ±1 mm accuracy, even when obstacles are present in the vessel or when process conditions like vapors and gas blankets change.
-
HistoROM Data Management: This concept ensures that all device parameters are backed up. It facilitates fast commissioning and maintenance, as configuration data can be easily transferred if the transmitter electronics are replaced.

การใช้งานหลัก
-
Process Tanks with Internal Fittings: Perfect for vessels containing agitators, baffles, or cooling coils where a focused beam is required to avoid interference.
-
Narrow Nozzle Installations: The high frequency allows for high-performance measurement even when the sensor must be mounted on small-diameter nozzles.
-
Hygienic and Aggressive Liquids: Suitable for various chemical and utility applications where non-contact measurement is necessary to prevent sensor corrosion or product contamination.
-
Inventory Management: High accuracy of ±1 mm makes it suitable for precise tracking of high-value liquids in storage tanks.
-
Safety-Instrumented Systems (SIS): Used as a reliable high-level or low-level alarm in loops requiring SIL-rated instrumentation.
