技術的特徴と設計
-
Extreme Temperature and Pressure: The FMR62B is built for the “heavy-duty” category. Its mechanical design allows for operation in conditions as low as -196 °C and as high as +450 °C, ensuring reliability in everything from LNG storage to high-temperature chemical reactors.
-
Unmatched 80m Range and Precision: By combining a long-range capability of 80 meters with an accuracy of ±1 mm, this sensor is ideal for tall inventory tanks. The 80 GHz signal remains focused over long distances, minimizing signal loss and interference.
-
Advanced Safety and SIL Management: Developed according to IEC 61508, the FMR62B is designed for SIL 2 and SIL 3 applications. It features unique guided wizards for SIL-locking and proof testing, which significantly reduces the risk of human error during safety-critical configurations.
-
Heartbeat Technology: This suite provides a “pulse check” of the process and the instrument. It offers continuous monitoring and can identify anomalies such as foam formation or antenna buildup in real-time. The on-demand verification feature creates a documented report for regulatory compliance without interrupting the process.
-
Intuitive Troubleshooting: The local display doesn’t just show error codes; it provides clear, text-based recommended actions. This “easy handling” philosophy speeds up maintenance and reduces the need for extensive technical manuals on-site.
-
High Beam Focusing: Even in vessels filled with internal heating coils, agitators, or baffles, the narrow beam of the 80 GHz signal navigates through obstacles to find the true liquid surface, ensuring a stable measurement in turbulent conditions.
