SYC21料位開關
SYC21音叉物位開關產品概述
SYC21型音叉式物位開關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。該產品由發訊叉體和放大器組成，叉體根部壓有兩組壓電晶體，分別作為驅動器和檢測器。驅動器使叉體以固有頻率振動，檢測器將振動信號轉換為電壓信號。當物料接觸叉體時，振動頻率和振幅變化觸發繼電器輸出開關信號，實現高精度物位控制。傳感器采用316不銹鋼材質，具有良好的耐腐蝕性，可廣泛應用于自來水、廢水處理、化工溶液等多種工業場景。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
技術特點與優勢
該產品具有抗干擾能力強、不受介質電參數和密度影響的特性，在結垢、湍流、氣泡、振動等復雜工況下仍能穩定工作。獨特的壓電驅動技術無需機械傳動部件，減少了磨損風險。音叉部分經過精密調諧，確保200Hz左右的穩定振動頻率，配合智能電路設計的2-7秒可調延時功能，有效消除物料波動引起的誤報警。產品采用模塊化設計，維護簡便，可提供側裝或頂裝方式適應不同容器安裝需求。對于高溫高壓環境，特殊設計的叉體可承受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
典型應用場景
產品在食品飲料行業表現優異，特別適用于啤酒、飲料生產中的發酵罐和儲罐液位控制。化工領域可測量酸堿溶液、泥漿及易產生氣體的液體，造紙行業的紙漿和膠水監測同樣適用。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用方向。設備安裝靈活，既可通過螺紋連接直接安裝在倉壁側面，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。16
Typical Applications
The switch excels in food & beverage applications, particularly for啤酒發酵劑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

產品描述
阻旋料位開關也有的稱之為阻旋物位計或者阻旋料位開關、阻旋物位開關等，主要是根據它具體的不同用途的不同名稱。阻旋式料位開關是采用交流微電機經減速后，帶動檢測葉片慢速旋轉。當被測物料的料位上升使葉片的轉動受到阻擋時，檢測機構主軸產生旋轉位移。此位移先使一個微動開關動作，發出有料的信號。隨后另一個微動開關動作，切斷微電機的電源使其停止轉動。只要倉內的料位不變，此種狀態便將一直保持下去。
