SYC21料位開關(guān)
SYC21音叉物位開關(guān)產(chǎn)品概述
SYC21型音叉式物位開關(guān)是一種先進的物位檢測儀表，采用振動式測量原理，適用于液體和流動性良好的固體粉料限位檢測。該產(chǎn)品由發(fā)訊叉體和放大器組成，叉體根部壓有兩組壓電晶體，分別作為驅(qū)動器和檢測器。驅(qū)動器使叉體以固有頻率振動，檢測器將振動信號轉(zhuǎn)換為電壓信號。當(dāng)物料接觸叉體時，振動頻率和振幅變化觸發(fā)繼電器輸出開關(guān)信號，實現(xiàn)高精度物位控制。傳感器采用316不銹鋼材質(zhì)，具有良好的耐腐蝕性，可廣泛應(yīng)用于自來水、廢水處理、化工溶液等多種工業(yè)場景。1
SYC21 Fork Level Switch Product Description
The SYC21 fork level switch is an innovative vibration-based level detection device designed for both liquid and free-flowing solid materials. Its working principle relies on the change in resonant frequency when the fork tines contact the material. The sensor consists of a vibrating fork and an amplifier, with two sets of piezoelectric crystals at the fork base - one for driving vibration and another for signal detection. When material impedes fork movement, the vibration amplitude decreases and frequency shifts, triggering relay output. The 316 stainless steel construction ensures reliable performance in mildly corrosive environments. Typical applications include monitoring levels in礦泉水, paper pulp, dyes,啤酒發(fā)酵罐, and柴油 storage tanks. The compact design and simple installation make it suitable for various industrial process control systems.1
技術(shù)特點與優(yōu)勢
該產(chǎn)品具有抗干擾能力強、不受介質(zhì)電參數(shù)和密度影響的特性，在結(jié)垢、湍流、氣泡、振動等復(fù)雜工況下仍能穩(wěn)定工作。獨特的壓電驅(qū)動技術(shù)無需機械傳動部件，減少了磨損風(fēng)險。音叉部分經(jīng)過精密調(diào)諧，確保200Hz左右的穩(wěn)定振動頻率，配合智能電路設(shè)計的2-7秒可調(diào)延時功能，有效消除物料波動引起的誤報警。產(chǎn)品采用模塊化設(shè)計，維護簡便，可提供側(cè)裝或頂裝方式適應(yīng)不同容器安裝需求。對于高溫高壓環(huán)境，特殊設(shè)計的叉體可承受300℃過程溫度和4.0MPa壓力。611
Technical Features and Benefits
This level switch demonstrates exceptional resistance to process disturbances including scaling, agitation, bubbles and medium viscosity changes. The all-solid-state design with piezoelectric excitation eliminates mechanical wear points, ensuring long service life. Precision-tuned forks maintain stable 200Hz oscillation, while adjustable 2-7 second delay prevents false signals from material surges. The modular construction simplifies maintenance, with side-mounted or top-mounted installation options for different vessel configurations. Special fork variants withstand extreme conditions up to 300°C process temperature and 4.0MPa pressure. The measurement remains unaffected by variations in dielectric constant or material density, providing reliable switching for diverse industrial applications from粘稠膠水to粉狀原料.621
典型應(yīng)用場景
產(chǎn)品在食品飲料行業(yè)表現(xiàn)優(yōu)異，特別適用于啤酒、飲料生產(chǎn)中的發(fā)酵罐和儲罐液位控制。化工領(lǐng)域可測量酸堿溶液、泥漿及易產(chǎn)生氣體的液體，造紙行業(yè)的紙漿和膠水監(jiān)測同樣適用。對于固體物料，能夠可靠檢測流動性良好的粉料如水泥、面粉等。危險場所如柴油儲罐的物位報警也是其重要應(yīng)用方向。設(shè)備安裝靈活，既可通過螺紋連接直接安裝在倉壁側(cè)面，也可采用法蘭方式固定在頂部避開進料沖擊位置，管道安裝則可防止泵的空轉(zhuǎn)。16
Typical Applications
The switch excels in food & beverage applications, particularly for啤酒發(fā)酵劑and beverage storage tank level control. In chemical processing, it reliably monitors酸堿溶液, slurry and gas-evolving liquids. Paper industry applications include紙漿and adhesive level detection. For solid materials, it effectively measures free-flowing powders like水泥原料and面粉. Hazardous area installations such as柴油tank alarms represent another key application. Flexible mounting options include threaded side-wall installation, flanged top-mounting to avoid material impact, and pipeline mounting to prevent pump dry-running. The vibration principle ensures reliable operation regardless of material conductivity or dielectric properties.122

產(chǎn)品描述
阻旋料位開關(guān)也有的稱之為阻旋物位計或者阻旋料位開關(guān)、阻旋物位開關(guān)等，主要是根據(jù)它具體的不同用途的不同名稱。阻旋式料位開關(guān)是采用交流微電機經(jīng)減速后，帶動檢測葉片慢速旋轉(zhuǎn)。當(dāng)被測物料的料位上升使葉片的轉(zhuǎn)動受到阻擋時，檢測機構(gòu)主軸產(chǎn)生旋轉(zhuǎn)位移。此位移先使一個微動開關(guān)動作，發(fā)出有料的信號。隨后另一個微動開關(guān)動作，切斷微電機的電源使其停止轉(zhuǎn)動。只要倉內(nèi)的料位不變，此種狀態(tài)便將一直保持下去。
