BR-7X料位開(kāi)關(guān)產(chǎn)品介紹（中文）
BR-7X耐高溫阻旋料位開(kāi)關(guān)是一種用于固態(tài)物料（包括粉狀、粒狀、塊狀、膠狀等）的物位控制設(shè)備。該產(chǎn)品采用永磁電機(jī)帶動(dòng)葉片旋轉(zhuǎn)的設(shè)計(jì)原理，當(dāng)被檢測(cè)物料上升至葉片位置時(shí)，葉片轉(zhuǎn)動(dòng)受阻，阻力通過(guò)傳動(dòng)軸傳遞到接線盒內(nèi)的檢測(cè)裝置，輸出開(kāi)關(guān)信號(hào)并切斷電機(jī)電源；當(dāng)物料下降時(shí)，葉片阻力消失，裝置依靠彈簧拉力恢復(fù)旋轉(zhuǎn)狀態(tài)。其特點(diǎn)是葉片過(guò)載時(shí)馬達(dá)自動(dòng)打滑保護(hù)，工作溫度范圍覆蓋-20℃至80℃（高溫型可達(dá)350℃），適用于化工、塑料、鋼鐵、電力、水泥、制藥等行業(yè)。產(chǎn)品采用不銹鋼材質(zhì)接觸物料部分，具有密封防塵設(shè)計(jì)，支持水平、垂直或傾斜安裝方式，且扭力大小可根據(jù)物料比重調(diào)節(jié)。1610
Introduction to BR-7X Level Switch (English)
The BR-7X high-temperature resistant rotary paddle level switch is designed for solid material detection, including powders, granules, lumps, and viscous substances. It operates by driving a rotating blade via a permanent magnet motor. When material contacts the blade, the rotation resistance triggers a switch signal and cuts off the motor power; when material level drops, the spring mechanism restores rotation. Key features include automatic motor slip protection under overload, operational temperature range from -20°C to 80°C (high-temperature version up to 350°C), and adaptability to industries like chemicals, plastics, cement, and food processing. The stainless-steel blade and sealed construction ensure durability, while adjustable torque accommodates varying material densities. Installation flexibility allows horizontal, vertical, or angled mounting in silos or hoppers.1622
產(chǎn)品結(jié)構(gòu)與功能細(xì)節(jié)（中文）
該設(shè)備采用機(jī)電分離式結(jié)構(gòu)，維護(hù)時(shí)無(wú)需整體拆卸，獨(dú)特油封設(shè)計(jì)防止粉塵滲入軸承。葉片規(guī)格和軸長(zhǎng)可定制，適用于不同容積的料倉(cāng)。其工作原理基于物料對(duì)旋轉(zhuǎn)葉片的機(jī)械阻力，通過(guò)微動(dòng)開(kāi)關(guān)轉(zhuǎn)換信號(hào)，觸點(diǎn)容量為10A/250VAC。針對(duì)低密度物料（≥0.5g/cm³）可調(diào)整彈簧至弱檔位提升靈敏度，高密度物料則調(diào)至強(qiáng)檔位避免誤觸發(fā)。防護(hù)等級(jí)達(dá)IP65，適合多粉塵環(huán)境，且特殊鐮刀型葉片設(shè)計(jì)能減少物料堆積影響。102023
Technical Specifications (English)
Structurally, the BR-7X features a motor-compartment separation design for easy maintenance, with dust-proof bearings via specialized oil seals. Customizable blade sizes and shaft lengths (up to 500mm optional) adapt to diverse bin configurations. The mechanism utilizes material-induced mechanical resistance to activate a microswitch (SPDT contact, 10A/250VAC). Sensitivity adjustment via 4-stage spring tension settings accommodates materials from 0.5g/cm³ density. The IP65-rated enclosure withstands harsh environments, while optional sickle-shaped blades minimize material adhesion. Standard power options include 110VAC/220VAC or 24VDC versions with ≤4W consumption.61622
應(yīng)用場(chǎng)景與優(yōu)勢(shì)（中文）
在水泥廠煤粉倉(cāng)、飼料廠原料倉(cāng)等場(chǎng)景中，BR-7X能穩(wěn)定檢測(cè)流動(dòng)性差異大的物料，如遇蓬松纖維類(lèi)物質(zhì)時(shí)可更換加長(zhǎng)葉片。相比電容式開(kāi)關(guān)，其機(jī)械式檢測(cè)不受介質(zhì)介電常數(shù)變化影響；相較于音叉開(kāi)關(guān)，阻旋設(shè)計(jì)對(duì)低密度物料更敏感。設(shè)備運(yùn)行功耗低（約3W），啟動(dòng)延時(shí)0.7秒，槳葉轉(zhuǎn)速1RPM，長(zhǎng)期連續(xù)運(yùn)轉(zhuǎn)穩(wěn)定性強(qiáng)，且過(guò)載保護(hù)機(jī)構(gòu)可避免外力損壞傳動(dòng)部件。102025
Applications & Advantages (English)
Ideal for coal bunkers in power plants or grain silos, the BR-7X reliably detects materials with varying flow properties, where extended blades are optional for fibrous substances. Compared to capacitive switches, its mechanical operation avoids dielectric constant interference; versus vibrating forks, it offers better sensitivity for lightweight powders. With low power consumption (3W), 0.7s start-up delay, and 1RPM blade speed, it ensures long-term stability. The overload clutch protects internal gears from damage during unexpected impacts or blockages.162225
