安裝與適用場景
該料位開關推薦采用側裝方式，安裝時探頭需與水平向下成20°夾角以優化檢測靈敏度，并需確保非感應部分伸入容器內部。對于高粘性物料或存在振動的工況，建議加裝防護擋板并保持探頭與倉壁300mm以上間距。產品廣泛應用于飼料、塑料粒子、煤粉、水泥等物料的滿倉/空倉報警，以及在污水處理中監測油水界面、沉淀物高度等場景。其緊湊的結構設計和無機械傳動部件特性，使其在粉塵大、腐蝕性強的環境中表現尤為突出。4717
SA120ADQ0420 Capacitance Level Switch Introduction
The SA120ADQ0420 is a high-performance capacitance-type level switch designed for detecting powders, granules and bulk solids in industrial applications. Utilizing advanced capacitive sensing principle, it accurately monitors material level by detecting dielectric constant changes, suitable for silos, tanks and conveyors in chemical, food, building material and environmental protection industries. The probe is constructed with stainless steel or PTFE coating, offering excellent corrosion and abrasion resistance for long-term operation within -20℃ to 80℃ range (extendable to 200℃ for special versions). With G1 or DN40 flange mounting options, it provides flexible installation compatibility. 21127
Technical Features
Featuring modular design, this switch incorporates adjustable sensitivity circuitry (10pF standard/20pF optional) to adapt various material densities. Its anti-coating technology effectively prevents false signals caused by material adhesion. The probe is available in rod-type (up to 2000mm) or cable-type configurations for different vessel depths. The aluminum alloy junction box (IP65 rated) supports both AC220V and DC24V power supply, with output options including relay contact (3A/250VAC) or NPN transistor signal for PLC integration. The built-in delay function (0-12s adjustable) filters transient interference to enhance operational reliability. 4719
Installation Guidelines
Recommended side-mount installation requires 20° downward tilt of the probe to optimize sensitivity, ensuring non-sensing section extends into the vessel. For viscous materials or vibrating environments, protective baffles and 300mm clearance from vessel walls are advised. Typical applications include overfill/empty alarm for feedstocks, plastic pellets, coal dust and cement, as well as interface detection like oil-water separation in wastewater treatment. Its compact, non-mechanical design demonstrates superior performance in dusty and corrosive conditions. 41726
SA120ADQ0420料位開關
阻旋料位開關產品原理：阻旋料位開關是一種用于固態物料（包括粉狀、粒狀、塊狀、膠狀等）的物位控制器。其利用永磁電機帶動葉片旋轉，當被檢測物料上升至葉片位置時，葉片轉動受阻，該阻力通過傳動軸傳遞到接線盒內的檢測裝置，檢測裝置則向外輸出一個開關信號，并切斷電機電源使葉片停止轉動。當物料下降時，葉片阻力消失，檢測裝置便依靠彈簧的拉力恢復到原始狀態，葉片恢復旋轉狀態。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業得到了的應用。
