The Series PLS2 is an electromechanical level switch designed for level monitoring of bulk materials. The rotating measuring vane is driven by a brushless synchronous motor at one revolution per minute. As product builds up, the paddle rotation is impeded and the resulting motor torque activates the output switch and stops the motor. A spring mechanism reactivates the motor and returns the switch to normal state when the material no longer impedes the paddle rotation. A torque adjusting mechanism eliminates the need for different sized paddles. The PLS2 is designed with the industry standard 1-1/4" male NPT connection and unit can be side or top mounted.

PLS系列 旋葉式料位開關 采用磁力驅動,這個傳承了我們的Mark系列閥位指示系列產品幾十年的制造經驗。每分鐘一轉轉速的電機采用磁力驅動旋葉。當物料料位升高阻擋旋葉而產生的力矩使得開關動作,并切斷電機電源。當物料料位下降,不阻擋旋葉,彈簧的回力使得開關回位,電機也開始帶動旋葉旋轉。標準配置是全天候防護,可選防爆型的,它可側面安裝或頂部安裝。PLS型料位開關的工藝連接采用工業標準的1-1/4" NPT 外螺紋連接,可選法蘭連接方式。

DBLM系列 小型旋葉式料位開關可靠耐用,用于干物料的料位監測,特別適用于安裝空間受到限制的場合,這款小型的料位開關監測物料的高,中和低位,避免溢出,堵塞或空罐等。它以每分鐘一轉的速度由電機帶動四個塑料葉片旋轉,當物料阻止它旋轉時,它切斷電機電源,觸發開關動作。DBLM可選擇1-1/4" 到 3/4"異徑接頭來取代標準的接頭。
