9.8’(3 m)測量范圍,非接觸式變送器,4個SPST可編程繼電器
ULSM型超聲波液位傳感器為中等范圍應用提供非接觸、連續超聲波液位測量。超聲波技術與自動溫度補償相結合,可在幾乎所有條件下提供準確可靠的測量。模型ULSM具有故障保護邏輯,可通過自由軟件輕松配置為自定義應用,無需校準目標。使用自由軟件,模型ULSM可以編程傳輸一個輸出信號,以及設置四個繼電器用于控制應用。這種堅固耐用的設計帶有NEMA 6P潛水外殼,確保裝置耐用。
產品應用
水和廢水紙漿和紙張加工泵和工藝槽
功能
具有9.8´(3 m)的測量范圍,范圍精度為±0.2%
通過免費軟件,裝置可編程為傳輸輸出信號并操作四個繼電器用于控制應用
提供可靠、準確和非接觸式的兼容液體液位測量
非接觸技術提供無運動部件磨損、堵塞、腐蝕,或者像接觸技術一樣涂上涂層
繪圖軟件使有效測量表面僅為直徑為3英寸(76.2毫米)的柱體,不涉及梯子、管道,或其他坦克侵入剩余的聲音錐
超聲波技術與自動溫度補償相結合,可在幾乎所有條件下提供準確可靠的測量
故障安全邏輯可通過自由軟件輕松配置為定制應用,無需目標校準
