KOBOLD流量計DZR-6技術(shù)參數(shù)

KOBOLD數(shù)字流量計/監(jiān)測器DVK用于測量和監(jiān)測管道和軟管中的空氣的小流量和平均流量。該裝置是不需要維護(hù)的,它是熱式流量計原理。當(dāng)操作電壓被啟動時,傳感器的熱敏電阻會被加熱到高于介質(zhì)溫度的固定值。當(dāng)空氣(或氣體)流經(jīng)傳感器時,傳感器所產(chǎn)生的熱量被介質(zhì)吸收。

這意味著傳感器被冷卻到中間溫度。根據(jù)流速和流量的不同,溫度被均衡,傳感器的電阻按比例降低。流速可以通過測量電阻來確定。介質(zhì)溫度由第二個傳感器測量。兩個傳感器的電阻值通過惠特斯通電橋進(jìn)行比較,當(dāng)達(dá)到開關(guān)點時輸出繼電器觸發(fā)。

開關(guān)狀態(tài)由兩個LED發(fā)出信號(ON:LED);1*:綠色,2*:紅色)。KOBOLD數(shù)字式流量計DVK在實際工作中沒有壓力損失。通常情況下,改設(shè)備提供兩種版本(顯示器和傳感器在一起的緊湊型,顯示器和傳感器由電纜連接的分體式)。
