詳細(xì)介紹
BURKERT流量傳送177460子設(shè)備模塊可被作用流量傳送器（僅帶有“Low Power”式脈沖傳感器，型號為 8020、8030 和 8070）或脈沖分配器（帶有所有樣式的傳感器，型號 8020、8030 和 8070）。模塊會處理傳感器的輸出信號，顯示測得的流量并以 mA 為單位或以脈沖的形式將其發(fā)送到信號輸出端上。作為流量傳送器運(yùn)行時，傳感器的頻率信號會被轉(zhuǎn)換成一個 4 - 20 mA 信號（雙線運(yùn)行）。作為脈沖分配器運(yùn)行時，輸入頻率會被轉(zhuǎn)換成一個可調(diào)節(jié)的輸出頻率。通過操作單元，可在兩種運(yùn)行模式之間進(jìn)行切換。
