傳真:周傳瓊 工作: 寶德流量開關是利用探測頭溫度變化的原理設計。在探頭內置發熱傳感器及感熱傳感器,并與介質接觸。測量時,發熱傳感器發出恒定的熱量,當管道內沒有介質流動,感熱傳感器接收到的熱量是一個恒定值,當有介質流動時,感熱傳感器所接收到的熱量將隨介質的流速變化而變化,感熱傳感器將這溫差信號轉化成電信號,再經過電路轉換為對應的接點信號或模擬量信號。寶德流量開關殼體內部的流體通道上裝有一個內部裝有*磁鐵的活塞。當活塞被液流所引起的壓力差推動時,磁性活塞便會使設備內部的密封簧片開關動作,活塞的直徑決定了啟動流量。當液流減少時,不銹鋼彈簧會推動活塞復位。簧片開關被開動后,可遠傳報警或指示。或者可以將其集成在自動控制系統里。磁翻板液位計的工作原理是根據恒浮力原理,浮子在測量管內隨液位的升降而上、下移動,浮子內的*磁鋼通過耦合作用,驅動紅、白色翻柱翻轉180度,液位上升時翻柱由白色轉為紅色,下降時由紅色轉為白色,從而實現液位指示。浮筒式液位計的工作原理是根據變浮力原理,浮筒在桶壁內隨液位的升降而上下移動,浮筒上上拉的彈簧力和液位成正比,通過檢測彈簧力引起的扭轉角度的大小,來檢測液位的高低。熱擴散流量開關原理,熱擴散技術是一種在苛刻條件下性能優良、可靠性高的技術,其典型原理是當兩個傳感元件被置于流體中時,其中一個被加熱,另一個用于感應過程溫度。兩個傳感元件之間的溫差與過程流速及過程介質的性質有關。兩個傳感元件之間的溫差在無流量狀態下zui大,但隨著流量的增加,被加熱的傳感元件冷卻,溫差減小。流體流速直接影響熱擴散的程度。
