法國(guó)ATMI 浮動(dòng)液位開關(guān) SOBA EP |
--適合于測(cè)量飲用水的液位開關(guān)
法國(guó)ATMI公司是9001-2000認(rèn)證公司,是專業(yè)生產(chǎn)測(cè)量液體和固體浮動(dòng)開關(guān),傾斜開關(guān)的公司。在過(guò)去的34年里,ATMI已經(jīng)努力成為能生產(chǎn)出高質(zhì)量浮動(dòng)液位開關(guān)的公司,這些液位開關(guān)可以廣泛應(yīng)用于多領(lǐng)域中,它們外形簡(jiǎn)單;質(zhì)量;經(jīng)濟(jì)實(shí)惠,是針對(duì)那些對(duì)產(chǎn)品各方面要求非常嚴(yán)格的客戶和供應(yīng)商而制造的。ATMI公司至始至終堅(jiān)持對(duì)產(chǎn)品質(zhì)量的嚴(yán)格要求和不斷創(chuàng)新的原則。 20類產(chǎn)品可以測(cè)量很多液體和固體介質(zhì): / 純凈水;污水;廢水,海水等 /腐蝕性液體:酸性的;有溶解能力的;燃料;碳?xì)浠衔铮痪凭鹊?/div> /爆炸性環(huán)境:氣體(0,1,2 級(jí)),灰塵(20,21,22級(jí))有ATEX(認(rèn)證 /測(cè)量飲用水有ACS(Sanitary Conformity Certificate)認(rèn)證 /有3種類型液位開關(guān)用來(lái)測(cè)量?jī)A斜度液位,可以檢測(cè)填充物合適填滿 /谷類食品測(cè)量,如:燕麥,大米,小麥,大豆,玉米,面粉等的測(cè)量 /粉末測(cè)量,如:木屑,石灰,水泥等的測(cè)量 |
浮球材質(zhì):AISI 316SS,溫度:-10℃~150℃,開關(guān)指示:5A/250VAC,防護(hù):IP65
AT0系列限位開關(guān)為德國(guó)進(jìn)口產(chǎn)品,同時(shí)擁有高質(zhì)量和低價(jià)格的優(yōu)勢(shì),廣泛適用于多種用途,如電梯、立體停車庫(kù)、塑料機(jī)械、印刷機(jī)械等行業(yè)。其符合國(guó)際標(biāo)準(zhǔn)的安裝尺寸和多種操作頭,可以為不同應(yīng)用提供量體裁衣的產(chǎn)品和方案。技術(shù)說(shuō)明: §符合標(biāo)準(zhǔn):IEC/EN 60947; 認(rèn)證:CE,UL, CSA, GL,CCC等; §模塊化結(jié)構(gòu),防護(hù)等級(jí)IP65;§全絕緣; §符合DIN EN 61 131-2, 可用在電子電路中; §具備肯定斷開觸頭,符合IEC/EN 60 947-5-1標(biāo)準(zhǔn),保障人身和設(shè)備安全。
二、工作原理
音叉物位開關(guān)工作原理根據(jù)物料對(duì)振動(dòng)中的音叉有無(wú)阻力,探知料位是否到達(dá)或超過(guò)某高度,并發(fā)出通斷信號(hào)。音叉的傳感器以固有的頻率振動(dòng),當(dāng)音叉觸及液體或其他物料時(shí),其固有的振動(dòng)頻率降低,能量消耗在物料顆粒間的摩擦上,迫使振幅急劇衰減而停振,頻率的變化激活液位開關(guān),產(chǎn)生通斷信號(hào)。
三、典型應(yīng)用
★自來(lái)水、礦泉水 ★紙漿、膠水、染料 ★廢水、泥漿、酸堿溶液 ★可產(chǎn)生氣體的液體
★啤酒、啤酒發(fā)酵劑、飲料 ★柴油等危險(xiǎn)場(chǎng)所 ★流動(dòng)性好的固體粉料
四、技術(shù)參數(shù)
★ 供 電:24VDC(標(biāo)準(zhǔn)); 220VAC(可選) ★ 環(huán)境溫度:-20℃~70℃
★ 輸出方式:SPDT繼電器(單刀雙擲) ★ 介質(zhì)溫度:-40℃~150℃
★ 工作壓力:小于2MPa ★ 介質(zhì)密度:最低0.6g/cm3
★ 延 時(shí):1~60s(可選) ★ 高低位報(bào)警:現(xiàn)場(chǎng)可設(shè)置為高位或地位報(bào)警
★ 功 耗:0.5W ★ 外殼防護(hù):IP66
★ 電氣接口:M20*1.5 ★ 過(guò)程連接: NPT 1”螺紋安裝(標(biāo)準(zhǔn)螺紋)法蘭安裝(可選)
五、產(chǎn)品特點(diǎn)
★適應(yīng)性強(qiáng):
被測(cè)液體不同的電參數(shù)、密度對(duì)測(cè)量均不產(chǎn)生影響。結(jié)垢、攪動(dòng)、湍流、氣泡、振動(dòng)、中等粘度、高溫、高壓等惡劣條件對(duì)檢測(cè)也無(wú)影響。
★不需調(diào)校:
由于音叉限位開關(guān)的檢測(cè)不受被測(cè)介質(zhì)電參數(shù)及密度的影響,所以無(wú)論測(cè)量何種液體都不需現(xiàn)場(chǎng)調(diào)校。
★ 免于維護(hù):
由于音叉限位開關(guān)的檢測(cè)過(guò)程由電子電路完成,無(wú)活動(dòng)部件,所以一經(jīng)安裝投運(yùn)使用便不需要維護(hù)。
六、安裝說(shuō)明
音叉限位開關(guān)通常采用側(cè)裝(在倉(cāng)壁側(cè)面安裝)方式安裝與倉(cāng)體側(cè)壁對(duì)料位高度進(jìn)行上下限位置的檢測(cè);當(dāng)倉(cāng)體不便側(cè)面開孔時(shí)可采用頂裝(在倉(cāng)的頂部安裝)方式安裝,位置應(yīng)選擇能避開進(jìn)料時(shí)物料沖擊的位置;亦可安裝與管道上防止泵的無(wú)料運(yùn)行。 ★ 注意事項(xiàng):
安裝傳感器時(shí),將其插入罐體,用扳手卡住傳感器螺紋上部的六方形擰緊即可,注意不要用手?jǐn)Q動(dòng)殼體,因?yàn)樵跀Q緊的過(guò)程中會(huì)造成殼體與探桿間發(fā)生轉(zhuǎn)動(dòng)。在出廠時(shí)殼體內(nèi)部的電子單元與傳感器的連接電纜已接好,用力擰殼會(huì)使內(nèi)部的連接電纜拉斷。
a. 安裝施工時(shí)注意叉體不要受到強(qiáng)烈沖擊,以免損壞壓電晶體。
b. 儀表傳感器應(yīng)盡量避開物料的沖擊,水平安裝時(shí),叉體的兩個(gè)平行叉板應(yīng)取與地面垂直方式(此時(shí)叉體方向標(biāo)記沖上或者沖下),以保證物料能容易地從叉板之間流出。
七、產(chǎn)品調(diào)試
(一)檢查電源接線: 所有電源接線均接至電子單元頂部的端子板上(二)高低位報(bào)警選擇:
高低位報(bào)警可在現(xiàn)場(chǎng)由安裝在電子單元上的高低位報(bào)警選擇跳塊進(jìn)行設(shè)置。在右側(cè)時(shí)為高位報(bào)警,在左側(cè)時(shí)為低位報(bào)警(出廠時(shí)一般設(shè)為高位報(bào)警,也可以改變輸出接線)。
高位報(bào)警:當(dāng)物料淹沒(méi)傳感器中心端時(shí)(或儀表出現(xiàn)故障時(shí)),發(fā)出高位報(bào)警信號(hào)(跳塊位置如圖1所示)。
低位報(bào)警:當(dāng)物料低于傳感器中心端時(shí)(或儀表出現(xiàn)故障時(shí)),發(fā)出低位報(bào)警信號(hào)(跳塊位置如圖2所示)。
(三)繼電器的接線
每臺(tái)儀表帶有一組繼電器觸點(diǎn)(SPDT)單刀雙擲,繼電器僅作為一個(gè)開關(guān),不能直接帶動(dòng)報(bào)警器或其他較大功率設(shè)備動(dòng)作。所有控制信號(hào)均由電子單元頂部的端子排輸出。綠燈亮?xí)r表明繼電器工作正常(未報(bào)警,如圖3所示),燈滅時(shí)繼電器處于報(bào)警狀態(tài)(在斷電或儀表出現(xiàn)故障時(shí),繼電器也處于報(bào)警狀態(tài),如圖4所示)。
打開外殼上蓋,內(nèi)有接線端子、撥動(dòng)開關(guān)、發(fā)光二極管LED,靈敏度調(diào)節(jié)鈕。靈敏度調(diào)節(jié)鈕順時(shí)針旋轉(zhuǎn),靈敏度降低;逆時(shí)針旋轉(zhuǎn),靈敏度增高。通常出廠時(shí)已標(biāo)好無(wú)需調(diào)校,對(duì)于高粘度液體介質(zhì),一般調(diào)低靈敏度。
八、測(cè)試
出廠時(shí)一般調(diào)至高位報(bào)警,將音叉式物位開關(guān)接上電源,燈亮將其提起后垂直插入水中,插入深度應(yīng)大于25mm,此時(shí)輸出指示燈點(diǎn)滅;再將音叉提起離開水面,輸出指示燈變亮,說(shuō)明儀表工作正常。
