SF301音叉料位開關(guān)產(chǎn)品介紹（中英文）
SF301音叉料位開關(guān)是一種基于振動(dòng)短音叉技術(shù)的緊湊型物位檢測(cè)裝置，適用于液體、粉末及顆粒狀固體的料位監(jiān)測(cè)。該設(shè)備采用不銹鋼材質(zhì)音叉和本體，通過壓電晶體激發(fā)音叉固有頻率振動(dòng)，當(dāng)物料接觸音叉時(shí)振動(dòng)特性改變并觸發(fā)開關(guān)信號(hào)。其獨(dú)特設(shè)計(jì)可有效避免流動(dòng)、湍流、氣泡等因素干擾，安裝簡便無需校準(zhǔn)，且具備短路保護(hù)和免維護(hù)特性。產(chǎn)品提供螺紋或衛(wèi)生級(jí)連接方式，支持DC24V/AC220V供電和繼電器/PNP輸出，適用于食品、化工、制藥等行業(yè)，工作溫度范圍-20℃至80℃，壓力承受力達(dá)1MPa。緊湊型結(jié)構(gòu)和"快速低落"音叉設(shè)計(jì)使其對(duì)高粘度液體響應(yīng)更靈敏，磁性測(cè)試點(diǎn)便于現(xiàn)場功能驗(yàn)證。1619
The SF301 tuning fork level switch is a compact device utilizing short-fork vibration technology for reliable detection of liquids, powders and granular solids. Its stainless steel fork and housing are excited by piezoelectric crystals to maintain resonant frequency, which shifts upon material contact to generate switching signals. The innovative design ensures immunity to flow turbulence, bubbles and coating effects while requiring no calibration. Featuring plug-and-play installation with threaded or sanitary connections, it supports DC24V/AC220V power supply and offers relay/PNP outputs for PLC integration. Ideal for food processing, chemical and pharmaceutical applications, the switch operates at -20℃ to 80℃ with 1MPa pressure tolerance. The "fast-drain" fork design enhances response for viscous media, and integrated magnetic test point simplifies functional verification. 81121
核心功能特點(diǎn)
SF301采用機(jī)電一體化設(shè)計(jì)，無活動(dòng)部件避免機(jī)械磨損，電子元件具備自診斷功能并通過LED顯示狀態(tài)。音叉長度僅50mm（視連接方式），最小檢測(cè)密度液體≥0.7g/cm³、固體≥0.1g/cm³，安息角要求≥20°。衛(wèi)生級(jí)版本表面粗糙度Ra<0.8μm，可耐受150℃蒸汽清洗。產(chǎn)品提供三種靈敏度模式，響應(yīng)時(shí)間1-60秒可調(diào)，防護(hù)等級(jí)滿足IP65要求，特別適合料倉溢流保護(hù)、泵控系統(tǒng)和泄漏檢測(cè)等場景。6819
The SF301 employs monolithic construction with no moving parts to eliminate mechanical wear. Self-monitoring electronics with LED status indication ensure operational reliability. With mere 50mm fork immersion (connection-dependent), it detects media as light as 0.7g/cm³(liquid)/0.1g/cm³(solid) at repose angles ≥20°. Sanitary models feature Ra<0.8μm finish for CIP cleaning at 150℃. Three sensitivity modes and 1-60s adjustable response time accommodate diverse applications including overfill prevention, pump control and leak detection, while IP65 protection guarantees durability. 112123
應(yīng)用場景說明
該設(shè)備廣泛應(yīng)用于石化儲(chǔ)罐液位報(bào)警、飲料灌裝線控制、污水處理廠泵保護(hù)等場合。在面粉廠可監(jiān)測(cè)筒倉料位，制藥行業(yè)能檢測(cè)粘稠藥液，其抗粘附特性適用于瀝青等易掛壁介質(zhì)。安裝時(shí)需避開物料直接沖擊位置，建議與入料口保持1米以上距離。典型應(yīng)用包括：防止儲(chǔ)罐溢流、檢測(cè)管道泄漏、批量處理控制等，通過不同安裝角度適應(yīng)立式/臥式容器。11421
Typical applications include level alarms in petrochemical tanks, filling line control in beverage plants, and pump protection in wastewater treatment. Flour silos monitoring, viscous pharmaceutical liquid detection, and asphalt level measurement benefit from its anti-coating performance. Installation should avoid direct material impact zones with ≥1m distance from feed inlets. Common uses encompass overflow prevention, pipeline leak detection, and batch processing control through versatile mounting orientations for vertical/horizontal vessels. 61519
SF301料位開關(guān)
阻旋料位開關(guān)產(chǎn)品原理：阻旋料位開關(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。
