Technical Characteristics and Chemical Resilience
-
PTFE-Filled Flush Antenna: For applications involving highly corrosive or aggressive media, the FMR62 features a completely PTFE-filled, flush-mounted horn antenna. This design ensures that no metal parts are exposed to the process, maximizing system availability and sensor lifespan in harsh chemical environments.
-
High Beam Focusing: The 80 GHz frequency produces a narrow beam angle that allows the sensor to navigate around internal vessel fittings such as heating coils, agitators, and baffles. This precision ensures a stable signal even in complex tank geometries.
-
Compact PEEK Antenna: The integrated PEEK antenna design allows the FMR62 to be used with very small process connections (e.g., 1.5″ threads), making it a versatile choice for skids and smaller vessels where space is limited.
-
Heartbeat Technology: This integrated suite provides continuous self-diagnostics and on-demand verification. It can detect process-related issues like antenna buildup or foam formation, allowing for predictive maintenance without process interruption.
-
Safety by Design: Developed for SIL3 applications (in homogeneous redundancy), the FMR62 simplifies safety management with the world’s easiest proof test concept for SIL and WHG, significantly reducing operational downtime and engineering effort.
-
Multi-Echo Tracking: Enhanced algorithms allow the device to accurately identify and track the liquid level with ±1 mm precision, regardless of changing media, temperature layers, or vapors within the tank.
