                                日本東和PRL-100防水防油阻旋式料位控制器AC220V

                                技術參數:

                                電源: 110VAC 220VAC DC24V

                                接點容量: 250VAC 5A

                                葉片轉速:1RPM

                                防護等級: IP65

                                導線入口規格:G1/2"

                                適用于比重:0.6g/cm3

                                溫度范圍::-20~70(高溫型耐400)

                                比重小于0.6g/cm3,選用HL-400

                                工作原理:

                                采用交流微電機經減速后,帶動監測葉片慢速旋轉,當物料的料位上升使葉片的轉動受到阻擋時,檢測機構便圍繞主軸產生旋轉位移。此位移首先使一個微動開關動作,發出有料的信號。隨后另一個微動開關動作,切斷微電機的電源使其停止轉動。只要倉內的料位不變,此種狀態便將一直保持下去。

                                  當料位下降檢測葉片不再受到阻擋時,檢測機構便依靠彈簧拉力恢復原態。首先一個微動開關動作,接通電機電源使其旋轉。隨后另一個微動開關動作發出無料信號,只要沒有物料阻擋監測葉片的轉動,此種狀態將一直保持下去

                                  測量工藝:

                                  1.物料自然堆積會產生堆積傾斜,所以固體物料的料面是不平整的,很難明確料位的準確高度;物料進出時,存在滯留區,影響料位*低位置點的測量。

                                  2.料斗或儲倉中,固體物料內部易存在大的孔隙,形成拱橋。粉料內部易存在小的間隙。前者影響對物料儲量的計算,而后者則在振動或溫度、壓力變化時使物位也隨之變化。

                                  界面測量中常出現的問題是界面不明確,渾濁或泡沫的存在會影響測量結果。此外,容器內攪拌、管道和加熱等設備的存在也會對物位檢測帶來一定的影響,特別是像雷達波、超聲波這些依賴回波信號測量的物位儀表。

                                  應用:

                                  阻旋式料位控制器用于檢測固態物料(粉裝、顆粒)的料位高度,多用于工業的現場,屬于物位控制設備。其優秀的密封設計、過載保護能力以及簡易的安裝方式,使其廣泛用于飼料、食品、制藥、化工、塑料、建筑、肥料等行業。
