                                  東和料位開關是由磁簧開關和浮球組成,浮球內有磁性材料,在密閉的非導磁金屬管或塑料管內設置一個或多個磁簧開關,然后將導管穿過一個或多個帶有磁性材料的浮球,并利用固定雙環控制浮球與磁簧開關在相關位置上。
                                 
                                  浮球隨著液體上升或下降,利用球內磁鐵去吸引磁簧開頭的接點,產生開與關的動作,作液位控制或指示(當浮球靠近磁簧開關是導通;離開時開關斷開),常開和常閉是沒有注入液體時的狀態??刂凭€路與被測介質*隔離,可實現高溫、高壓下的液位控制;可根據需要實現多點、遠距離控制,多種連接方式;法蘭、螺紋等,可滿足不同環境的需求,應用范圍廣,水處理、化工、食品、醫藥、包裝、電子、船舶、紡織、液壓等行業均可使用。
                                 
                                  東和料位開關是一種結構簡單、使用方便、安全可靠的液位控制器,它比一般機械開關體積小、速度快、工作壽命長,與電子開關相比,它又有抗負載沖擊能力強的特點,其在造船、造紙、印刷、發電機設備、石油化工、食品工業、水處理、電工、染料工業、油壓機械等方面都得到了廣泛的應用。

                                東和料位開關

                                 


                                 
                                  東和料位開關調試:
                                 
                                  (1)浮球上下浮動經過調定的上下液位時,繼電器動作特點是:浮球上浮經下液位時,繼電器不動作,直至上浮到上液位,繼電器斷開。浮球下降經上液位時,繼電器不動作,直至下降到下液位,繼電器閉合。
                                 
                                  (2)在浮球沉到距底部1cm高度左右;發出上液位信號的位置,約在浮球升到距頂部1cm高度左右。
                                 
                                  (3)控制器電氣盒內,帶有刻度1—6的旋鈕是高度旋鈕,用于調整上下液位間的相對高度,左上角帶鎖緊螺母的小旋鈕是調零旋鈕,用于在低溫下調定起始下液位。
                                 
                                  (4)可調液位范圍的確定原則是:在正常運轉情況下,以供液電磁閥不頻繁動作為準。
                                 
                                  (5)在制冷工藝中,只要求在桶內垂直高度的1/3左右有下液位信號發出,能使主閥供液即可。
                                 
                                  (6)當線包處于-30℃以下低溫條件時,因電阻值改變很大,以至發不出信號,這時可轉動調零旋鈕,將下液位信號調出,調好后將鎖緊螺母擰緊。
