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(guān) 采用磁力驅(qū)動(dòng)，這個(gè)傳承了我們的Mark系列閥位指示系列產(chǎn)品幾十年的制造經(jīng)驗(yàn)。每分鐘一轉(zhuǎn)轉(zhuǎn)速的電機(jī)采用磁力驅(qū)動(dòng)旋葉。當(dāng)物料料位升高阻擋旋葉而產(chǎn)生的力矩使得開關(guān)動(dòng)作，并切斷電機(jī)電源。當(dāng)物料料位下降，不阻擋旋葉，彈簧的回力使得開關(guān)回位，電機(jī)也開始帶動(dòng)旋葉旋轉(zhuǎn)。標(biāo)準(zhǔn)配置是全天候防護(hù)，可選防爆型的，它可側(cè)面安裝或頂部安裝。PLS型料位開關(guān)的工藝連接采用工業(yè)標(biāo)準(zhǔn)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(guān)可靠耐用，用于干物料的料位監(jiān)測(cè)，特別適用于安裝空間受到限制的場(chǎng)合，這款小型的料位開關(guān)監(jiān)測(cè)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(zhuǎn)的速度由電機(jī)帶動(dòng)四個(gè)塑料葉片旋轉(zhuǎn)，當(dāng)物料阻止它旋轉(zhuǎn)時(shí)，它切斷電機(jī)電源，觸發(fā)開關(guān)動(dòng)作。DBLM可選擇1-1/4" 到 3/4"異徑接頭來取代標(biāo)準(zhǔn)的接頭。
