? 快速簡(jiǎn)便的調(diào)試，更*的“現(xiàn)場(chǎng)智能"過程信號(hào)處理技術(shù)
? 采用高頻的雙核處理器技術(shù)，使回波信號(hào)處理更快速，更可靠
? *的信噪比
? 自導(dǎo)式的快速啟動(dòng)方式
? 24 GHz 提供了優(yōu)良的固體表面反射性能
? 100 米量程適用于大量程和苛刻工況
? 瞄準(zhǔn)器提高了傾斜的固體表面的信號(hào)質(zhì)量
? 使用紅外本安手持編程器或者通過 SIMATIC PDM 或者 HART 手操器
應(yīng)用
SITRANS LR 460 在有高濃度粉塵和介電常數(shù)極低的場(chǎng)合下均能提
供可靠測(cè)量。通過所有 SITRANS LR 460 固體型中集成的瞄準(zhǔn)器，
可實(shí)現(xiàn)*固體定位和測(cè)量。
SITRANS LR 460 *的過程信號(hào)處理可以適用于簡(jiǎn)單以及復(fù)雜的
固體測(cè)量應(yīng)用。
SITRANS LR 460 的特點(diǎn)為堅(jiān)固型外殼、法蘭與喇叭元件。它不受
容器中的大氣或溫度條件的影響。
對(duì)于粘濕的固體介質(zhì)可選防塵罩；
另外有吹掃裝置應(yīng)用于極度的粘性固體。
使用本安型紅外手操器，現(xiàn)場(chǎng)編程安全簡(jiǎn)便。SIMATIC PDM 能用
于簡(jiǎn)單的遠(yuǎn)地編程。通過 HART 或 PROFIBUS PA。
24GHz 的發(fā)射頻率和高信 / 噪比使其即使在測(cè)量低介電常數(shù)時(shí)，
仍有很好的反射信號(hào)。
