DMK-GF150A料位開(kāi)關(guān)
產(chǎn)品概述
DMK-GF150A阻旋式料位開(kāi)關(guān)是一種用于固態(tài)物料（包括粉狀、粒狀、塊狀等）的工業(yè)自動(dòng)化控制儀表。該產(chǎn)品采用螺紋安裝方式，扭力可調(diào)設(shè)計(jì)，能夠適應(yīng)不同比重物料的檢測(cè)需求。其接觸物料部分采用不銹鋼材質(zhì)，具有良好的耐腐蝕性和耐磨性，廣泛應(yīng)用于石油、化工、冶金、電力、醫(yī)藥、食品、造紙、建材等多個(gè)工業(yè)領(lǐng)域。14
工作原理
該料位開(kāi)關(guān)利用永磁電機(jī)帶動(dòng)葉片旋轉(zhuǎn)，當(dāng)被檢測(cè)物料上升至葉片位置時(shí)，葉片轉(zhuǎn)動(dòng)受阻，阻力通過(guò)傳動(dòng)軸傳遞到檢測(cè)裝置，輸出開(kāi)關(guān)信號(hào)并切斷電機(jī)電源；當(dāng)物料下降時(shí)，葉片阻力消失，檢測(cè)裝置依靠彈簧拉力恢復(fù)原始狀態(tài)，葉片重新旋轉(zhuǎn)。針對(duì)不同比重的物料，可通過(guò)調(diào)整彈簧拉力實(shí)現(xiàn)精準(zhǔn)檢測(cè)，比重大時(shí)調(diào)至較強(qiáng)，反之調(diào)至較弱。412

Product Overview
The DMK-GF150A rotary paddle level switch is an industrial automation control instrument designed for solid materials including powders, granules, and bulk solids. Featuring threaded installation and adjustable torque, it can accommodate materials with different specific gravities. The material-contact parts are made of stainless steel for excellent corrosion and wear resistance, making it suitable for petroleum, chemical, metallurgical, power, pharmaceutical, food, paper, and building materials industries.14
Working Principle
This level switch operates by using a permanent magnet motor to rotate the paddle. When rising material obstructs the paddle s rotation, the resistance is transmitted through the drive shaft to the detection unit, triggering a switch signal and cutting off motor power. As material level drops and resistance disappears, the detection unit resets via spring tension and the paddle resumes rotation. The spring tension can be adjusted according to material density for precise detection - stronger for heavier materials and weaker for lighter ones.412
Key Features
The DMK-GF150A boasts simple structure, easy installation and maintenance. Its unique oil seal design prevents dust ingress along the shaft, while the reliable motor ensures continuous operation. Multiple connection options include 1" pipe thread and optional flange connections, with both top-mounted and side-mounted installation available. It operates in temperatures from -40℃ to +60℃ with media temperature tolerance up to 200℃, and IP67 protection rating suits various industrial environments.148
Applications
This product is particularly suitable for detecting adhesive liquids, solid particles, dust and other materials in silos, chutes or containers. It can measure oil-water interfaces in petrochemical applications, monitor powdered materials in food/pharmaceutical industries, and detect cement/lime in construction materials. It can integrate with PLC or DCS systems for automated process monitoring and control.1410
