產品概述
120GHz調頻連續波雷達物位計僅需要80ms就能完成一次100m距離范圍完整的測量計算過程。這使得系統可以有更多的時間和資源處理儀表物位應用上的各類事物，比如：概率評估/預測/可信度分析/輸入輸出/通訊等。
DCRD1000B 采用PTFE透鏡天線全密閉灌封設計，并很好地解決了天線近場輻射抑制的結構處理，這使得它有很好的方向性性能，波束角控制在1度以內（批量性產品制造工藝差異，可能會偏差±0.3度左右）。
The 120GHz FMCW Radar level transmitter just need 80ms to finished the distance measurement & calculation process for 100m ranges. This allows the system to have more time and resources to deal with various kinds of things on level application of the instrument, such as: echo signal probability assessment / level prediction / level reliability analysis / input&output/ communication, etc.
DCRD1000B using PTFE lens antenna with hermetic potting design, there is a perfect solution which resolved the antenna near field radiation suppression issues, that makes it has a good directional performance and less 1 degrees beam angle (the mass product manufacturing process differences, may be biased ±0.3 degrees).
應用特點
120GHz調頻雷達物位計，特別適用于高溫、高壓或高粉塵、多攪拌空間的工況環境使用，它滿足了很多需要大量程同時要高精度的測量需求。
120GHz FMCW radar level transmitter, especially be used in the high temperature & pressure, strong dust & multiple mixing environment, it can satisfy many applications for a large range measurement with high-precision requirements.
