        德國寶德burkert8177型上海國與一級代理歡迎咨詢,burkert8177設(shè)備是一種無接觸式超聲波液位傳送器,用于在開放式或封閉式容器中連續(xù)測量液位。它適合液體和散料,幾乎適合所有的工業(yè)領(lǐng)域,特別是水和廢水管理。The Type 8177 is a non-contact ultrasonic level measuring device designed for continuous level measurement in open or closed vessels. The unit is suitable for liquids, but also for solids, in virtually all industries, particularly in water and waste water management.

超聲波液位測量儀特點如下:

1.      緊湊型傳感器,適合測量最高為 8 m 的液位

2.      4...20 mA/Hart - 雙線

3.      適合散料

4.      ATEX 許可

實圖如下
