PRL-501料位開關產品概述
PRL-501阻旋料位開關是一款專為粉粒體物料設計的工業級物位檢測設備,采用機械式接觸測量原理,適用于化工、水泥、食品、制藥等行業的料倉料位監測。該產品通過微型電機驅動不銹鋼葉片旋轉,當物料觸及葉片時觸發內部機構輸出開關信號,實現料位報警或控制功能。其結構設計注重耐負荷性能,可承受0-49kPa的罐內工作壓力,并支持500mm至2000mm多種桿長定制,滿足不同安裝場景需求。1915
核心功能與特點
PRL-501采用SUS304不銹鋼軸和葉片,配合丁腈橡膠密封件,具有良好的耐腐蝕性和密封性。獨特設計的扭力彈簧機構可根據物料比重(≥0.5g/cm³)調節靈敏度,確保檢測準確性。產品配備雙重保護機制:過載時離合器自動打滑保護電機,物料阻擋時自動切斷電源延長使用壽命。支持AC100-220V或DC24V多種電源輸入,輸出為1C接點(AC250V/5A),防護等級達IP65,適應-10℃至80℃的工作環境。葉片標準轉速為1RPM,檢測力矩約10N·cm,功耗僅2.5W。3812
安裝與應用優勢
該料位開關提供JIS5K65A鋁制法蘭安裝方式(可定制其他法蘭規格),建議安裝時避開進料口直沖位置并加裝防護板。水平或垂直安裝均可,特別適合粉體、顆粒等固態物料的滿倉/空倉檢測。其機械式結構無需復雜調試,抗粉塵干擾能力強,在物料流動工況下仍能穩定工作。油封設計有效防止粉塵沿軸滲入,維護時無需拆卸整機即可檢修內部組件。廣泛應用于飼料加工、塑料顆粒存儲、電廠煤倉等場景的料位控制。41324
PRL-501 Rotary Paddle Level Switch Introduction
The PRL-501 is a robust rotary paddle level switch designed for point level detection of powders and granular materials in industrial silos or hoppers. Its working mechanism utilizes a slowly rotating paddle (1 RPM) driven by a synchronous micro motor, which stops upon encountering material, triggering a SPDT switch signal. The device features customizable probe lengths from 500mm to 2000mm and withstands internal vessel pressures up to 49kPa, making it suitable for demanding applications in bulk material handling.11620
Key Technical Attributes
Constructed with SUS304 stainless steel shaft/paddle and aluminum alloy housing, the switch offers excellent corrosion resistance. The torque-adjustable spring mechanism accommodates materials with different bulk densities (≥0.5g/cm³). Standard models operate at 220VAC/50Hz (optional 110VAC/24VDC) with 2.5W power consumption, while the IP65-rated enclosure ensures reliable performance in dusty environments. The mechanical clutch protects the motor from overload, and the unique oil seal prevents material ingress along the rotating shaft. The switch maintains stable detection accuracy across temperature ranges from -10°C to 80°C.31519
Operational Benefits
Installation flexibility is provided through flange mounting (JIS5K65A standard), with optional custom flanges available. The contact-type measurement delivers real-time material presence feedback without being affected by material dielectric properties or humidity. Maintenance-friendly design allows internal component inspection without full disassembly. Typical applications include inventory control in cement silos, overfill prevention in plastic pellet storage, and process automation in food processing lines. The simple electromechanical design ensures long service life with minimal maintenance requirements.91224

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。
