安裝與適用場(chǎng)景
該料位開(kāi)關(guān)推薦采用側(cè)裝方式，安裝時(shí)探頭需與水平向下成20°夾角以優(yōu)化檢測(cè)靈敏度，并需確保非感應(yīng)部分伸入容器內(nèi)部。對(duì)于高粘性物料或存在振動(dòng)的工況，建議加裝防護(hù)擋板并保持探頭與倉(cāng)壁300mm以上間距。產(chǎn)品廣泛應(yīng)用于飼料、塑料粒子、煤粉、水泥等物料的滿倉(cāng)/空倉(cāng)報(bào)警，以及在污水處理中監(jiān)測(cè)油水界面、沉淀物高度等場(chǎng)景。其緊湊的結(jié)構(gòu)設(shè)計(jì)和無(wú)機(jī)械傳動(dòng)部件特性，使其在粉塵大、腐蝕性強(qiáng)的環(huán)境中表現(xiàn)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(kāi)關(guān)
阻旋料位開(kāi)關(guān)產(chǎn)品原理：阻旋料位開(kāi)關(guān)是一種用于固態(tài)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(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，該阻力通過(guò)傳動(dòng)軸傳遞到接線盒內(nèi)的檢測(cè)裝置，檢測(cè)裝置則向外輸出一個(gè)開(kāi)關(guān)信號(hào)，并切斷電機(jī)電源使葉片停止轉(zhuǎn)動(dòng)。當(dāng)物料下降時(shí)，葉片阻力消失，檢測(cè)裝置便依靠彈簧的拉力恢復(fù)到原始狀態(tài)，葉片恢復(fù)旋轉(zhuǎn)狀態(tài)。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業(yè)得到了的應(yīng)用。
