LS-YC-P-0料位開(kāi)關(guān)
產(chǎn)品概述
LS-YC-P-0音叉式物位開(kāi)關(guān)是一種通用型料位檢測(cè)設(shè)備，采用壓電晶體激勵(lì)原理實(shí)現(xiàn)非接觸式測(cè)量。該產(chǎn)品通過(guò)音叉振動(dòng)頻率變化檢測(cè)物料位置，適用于液體、粉料及顆粒狀介質(zhì)的限位報(bào)警與控制。其獨(dú)特設(shè)計(jì)使測(cè)量不受介質(zhì)電參數(shù)、密度、結(jié)垢或攪拌等因素影響，在石化、冶金、食品、建材等行業(yè)中表現(xiàn)穩(wěn)定可靠。134
工作原理
產(chǎn)品由發(fā)訊叉體和放大器組成，叉體根部壓裝兩組壓電晶體：一組作為驅(qū)動(dòng)器激發(fā)音叉振動(dòng)，另一組作為檢測(cè)器轉(zhuǎn)換振動(dòng)信號(hào)。當(dāng)物料接觸音叉時(shí)，振動(dòng)頻率發(fā)生突變，電子線路捕捉該變化并輸出開(kāi)關(guān)信號(hào)。整個(gè)過(guò)程無(wú)需機(jī)械傳動(dòng)部件，避免了傳統(tǒng)浮球或阻旋開(kāi)關(guān)的磨損問(wèn)題，實(shí)現(xiàn)免維護(hù)運(yùn)行。257
技術(shù)特點(diǎn)
該料位開(kāi)關(guān)具備優(yōu)異的工況適應(yīng)性，可在-30℃~150℃介質(zhì)溫度范圍內(nèi)穩(wěn)定工作，耐受2MPa壓力環(huán)境。316不銹鋼材質(zhì)的叉體設(shè)計(jì)能抵抗輕度腐蝕，且振動(dòng)特性具有自清潔功能，有效防止物料掛料。產(chǎn)品提供1~20秒可調(diào)輸出延時(shí)功能，支持AC220V或DC24V供電，繼電器輸出可直接控制設(shè)備啟停。安裝方式靈活，支持側(cè)裝、頂裝及管道安裝，特別適合不便開(kāi)孔的容器。468
典型應(yīng)用
廣泛應(yīng)用于自來(lái)水廠監(jiān)測(cè)水位、啤酒發(fā)酵罐液位控制、化工酸堿溶液報(bào)警、糧食倉(cāng)儲(chǔ)粉料檢測(cè)等場(chǎng)景。在紙漿、膠水、染料等高粘度介質(zhì)，以及柴油等危險(xiǎn)場(chǎng)所中同樣表現(xiàn)優(yōu)異。其緊湊結(jié)構(gòu)可替代傳統(tǒng)浮球開(kāi)關(guān)，尤其適用于存在湍流、氣泡或振動(dòng)干擾的復(fù)雜工況。2922
Product Overview
The LS-YC-P-0 tuning fork level switch is a versatile material detection device utilizing piezoelectric excitation technology for non-contact measurement. Designed to monitor liquid, powder and granular materials, it detects level positions through vibration frequency shifts, offering reliable performance in petrochemical, metallurgy, food processing and building material industries without being affected by dielectric properties or density variations. 357
Operating Principle
Featuring a vibration fork and amplifier assembly, the device employs two piezoelectric crystal sets: one as driver to generate vibrations and another as sensor to convert mechanical signals. Upon material contact, the frequency change triggers electronic circuitry to output switching signals. The all-electronic design eliminates moving parts, ensuring maintenance-free operation compared to mechanical float or paddle switches. 168
Key Features
This level switch demonstrates remarkable environmental adaptability, operating within -30℃~150℃ medium temperature range and 2MPa pressure conditions. The 316 stainless steel fork resists mild corrosion while its vibration characteristics prevent material buildup. Adjustable delay output (1-20s) and dual power options (AC220V/DC24V) with relay outputs facilitate direct equipment control. Flexible side/top/pipeline mounting suits various vessel configurations. 4922
Typical Applications
Ideal for water plant level monitoring, brewery fermentation control, chemical acid/alkali alarms and grain silo powder detection. Performs consistently with viscous media like pulp, glue, dyes, and hazardous areas including diesel storage. Its compact design replaces traditional float switches, particularly effective in turbulent, bubbly or vibrating environments. 257
LS-YC-P-0料位開(kāi)關(guān)
阻旋料位開(kāi)關(guān)產(chǎn)品原理：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）的物位控制器。其利用永磁電機(jī)帶動(dòng)葉片旋轉(zhuǎn)，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，該阻力通過(guò)傳動(dòng)軸傳遞到接線盒內(nèi)的檢測(cè)裝置，檢測(cè)裝置則向外輸出一個(gè)開(kāi)關(guān)信號(hào)，并切斷電機(jī)電源使葉片停止轉(zhuǎn)動(dòng)。當(dāng)物料下降時(shí)，葉片阻力消失，檢測(cè)裝置便依靠彈簧的拉力恢復(fù)到原始狀態(tài)，葉片恢復(fù)旋轉(zhuǎn)狀態(tài)。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業(yè)得到了的應(yīng)用。
