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(chǎn)品描述
阻旋料位開關(guān)也有的稱之為阻旋物位計(jì)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(jī)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(shí)，檢測機(jī)構(gòu)主軸產(chǎn)生旋轉(zhuǎn)位移。此位移先使一個(gè)微動開關(guān)動作，發(fā)出有料的信號。隨后另一個(gè)微動開關(guān)動作，切斷微電機(jī)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。
