RD-40 Rotary Paddle Level Switch Product Introduction (English)
The RD-40 rotary paddle level switch is an industrial control device designed for monitoring solid materials (including powders, granules, and bulk solids) in storage containers. Its working principle involves a micro-motor driving a rotating paddle through a transmission shaft connected to a clutch mechanism. When no material contacts the paddle, the motor operates continuously; upon material contact, the paddle stops rotating, triggering an electrical signal while cutting off power automatically. The adjustable shaft length accommodates varying installation depths in silos or hoppers, with SUS304 stainless steel paddle ensuring corrosion resistance. Featuring a specialized oil seal design, it effectively prevents dust infiltration along the shaft. The torque spring mechanism allows sensitivity adjustment based on material density (≥0.4g/cm³). This device finds applications in cement plants, chemical processing, food industries, and plastic manufacturing for open-container level control, helping minimize material waste from overfilling or empty runs. Its motor-gear separation structure simplifies maintenance, while overload protection automatically disengages the drive when excessive load is detected. With IP65 protection rating, it supports both horizontal and vertical mounting, equipped with M20×1.5 cable entry.51726
產(chǎn)品特點(diǎn)與優(yōu)勢(shì)（中文）
RD-40采用三軸承支撐結(jié)構(gòu)和雙層防塵設(shè)計(jì)，運(yùn)行穩(wěn)定性較高。葉片轉(zhuǎn)速為逆時(shí)針1rpm，旋轉(zhuǎn)力矩1N·m，適用于-20℃至80℃環(huán)境溫度。全密閉性外殼使其可在戶(hù)外使用，且無(wú)需整機(jī)拆卸即可進(jìn)行內(nèi)部檢修。安裝時(shí)建議避開(kāi)進(jìn)料口下方位置，側(cè)裝時(shí)需保持出線(xiàn)口垂直向下以防水滲入。對(duì)于高溫工況（最高200℃），可選用高溫型號(hào)。產(chǎn)品提供多種葉片規(guī)格可選，包括T型100×30mm、方型66×80mm等，用戶(hù)可根據(jù)物料特性選擇適配型號(hào)。機(jī)電聯(lián)動(dòng)部分采用潤(rùn)滑齒輪組件，減少運(yùn)動(dòng)部件磨損，延長(zhǎng)使用壽命。3911
Features and Advantages (English)
The RD-40 employs triple-bearing support and dual-layer dustproof construction for enhanced operational reliability. With a paddle rotation speed of 1rpm (counter-clockwise) and 1N·m torque, it operates within -20℃ to 80℃ ambient temperatures. The fully enclosed housing allows outdoor deployment, and internal components can be serviced without complete disassembly. Installation should avoid positions directly below feed inlets, with side-mounted units requiring downward-facing cable entries to prevent water ingress. High-temperature variants (up to 200℃) are available for extreme conditions. Multiple paddle configurations include T-type 100×30mm and square 66×80mm designs, allowing material-specific selection. Lubricated gear assemblies minimize wear on moving parts, extending service life. The simple mechanical design ensures minimal maintenance requirements while providing consistent performance across varying material densities and flow conditions.162328
