詳細(xì)介紹
橫河壓力變送器工作原理:當(dāng)壓力直接作用在測量膜片的表面,使膜片產(chǎn)生微小的形變,測量膜片上的高精度電路將這個(gè)微小的形變變換成為與壓力成正比的高度線性、與激勵(lì)電壓也成正比的電壓信號,然后采用芯片將這個(gè)電壓信號轉(zhuǎn)換為工業(yè)標(biāo)準(zhǔn)的4-2OmA電流信號或者1-5V電壓信號。由于測量膜片采用標(biāo)準(zhǔn)話集成電路,內(nèi)部包含線性及溫度補(bǔ)償電路,所以可以做到高精度和高穩(wěn)定性,變送電路采用的兩線制芯片,可以保證輸出兩線制4-2OmA電流信號,方便現(xiàn)場接線。

橫河壓力傳感器使用過程應(yīng)注意考慮下列情況:
1、防止變送器與腐蝕性或過熱的介質(zhì)接觸;
2、防止渣滓在導(dǎo)管內(nèi)沉積;
3、測量液體壓力時(shí),取壓口應(yīng)開在流程管道側(cè)面,以避免沉淀積渣;
4、測量氣體壓力時(shí),取壓口應(yīng)開在流程管道頂端,并且變送器也應(yīng)安裝在流程管道上部,以便積累的液體容易注入流程管道中;
5、導(dǎo)壓管應(yīng)安裝在溫度波動(dòng)小的地方;
6、測量蒸汽或其它高溫介質(zhì)時(shí),需接加緩沖管(盤管)等冷凝器,不應(yīng)使變送器的工作溫度超過極限;
7、冬季發(fā)生冰凍時(shí),安裝在室外的變送器必需采取防凍措施,避免引壓口內(nèi)的液體因結(jié)冰體積膨脹,導(dǎo)至傳感器損壞;
8、測量液體壓力時(shí),變送器的安裝位置應(yīng)避免液體的沖擊(水錘現(xiàn)象),以免傳感器過壓損壞;

日常維護(hù)
1、檢查安裝孔的尺寸:如果安裝孔的尺寸不合適,傳感器在安裝過程中,其螺紋部分就很容易受到磨損。這不僅會(huì)影響設(shè)備的密封性能,而且使壓力傳感器不能充分發(fā)揮作用,甚至還可能產(chǎn)生安全隱患。只有合適的安裝孔才能夠避免螺紋的磨損(螺紋工業(yè)標(biāo)準(zhǔn)1/2-20 UNF 2B),通常可以采用安裝孔測量儀對安裝孔進(jìn)行檢測,以做出適當(dāng)?shù)恼{(diào)整。
2、保持安裝孔的清潔:保持安裝孔的清潔并防止熔料堵塞對保證設(shè)備的正常運(yùn)行來說十分重要。在擠出機(jī)被清潔之前,所有的壓力傳感器都應(yīng)該從機(jī)筒上拆除以避免損壞。在拆除傳感器時(shí),熔料有可能流入到安裝孔中并硬化,如果這些殘余的熔料沒有被去除,當(dāng)再次安裝傳感器時(shí)就可能造成其頂部受損。清潔工具包能夠?qū)⑦@些熔料殘余物去除。然而,重復(fù)的清潔過程有可能加深安裝孔對傳感器造成的損壞。如果這種情況發(fā)生,就應(yīng)當(dāng)采取措施來升高傳感器在安裝孔中的位置。
3、選擇恰當(dāng)?shù)奈恢茫寒?dāng)壓力傳感器的安裝位置太靠近生產(chǎn)線的上游時(shí),未熔融的物料可能會(huì)磨損傳感器的頂部;如果傳感器被安裝在太靠后的位置,在傳感器和螺桿行程之間可能會(huì)產(chǎn)生熔融物料的停滯區(qū),熔料在那里有可能產(chǎn)生降解,壓力信號也可能傳遞失真;如果傳感器過于深入機(jī)筒,螺桿有可能在旋轉(zhuǎn)過程中觸碰到傳感器的頂部而造成其損壞。一般來說,傳感器可以位于濾網(wǎng)前面的機(jī)筒上、熔體泵的前后或者模具中。
4、仔細(xì)清潔;在使用鋼絲刷或者特殊化合物對擠出機(jī)機(jī)筒進(jìn)行清潔前,應(yīng)該將所有的傳感器都拆卸下來。因?yàn)檫@兩種清潔方式都可能會(huì)造成傳感器的震動(dòng)膜受損。當(dāng)機(jī)筒被加熱時(shí),也應(yīng)該將傳感器拆卸下來并使用不會(huì)產(chǎn)生磨損的軟布來擦拭其頂部,同時(shí)傳感器的孔洞也需要用清潔的鉆孔機(jī)和導(dǎo)套清理干凈。
5、保持干燥:盡管傳感器的電路設(shè)計(jì)能夠經(jīng)受苛刻的擠出加工環(huán)境,但是多數(shù)傳感器也不能防水,在潮濕的環(huán)境下也不利于正常運(yùn)行。因此,需要保證擠出機(jī)機(jī)筒的水冷裝置中的水不會(huì)滲漏,否則會(huì)對傳感器造成不利影響。如果傳感器不得不暴露在水中或潮濕的環(huán)境下,就要選擇具有*防水性的特殊傳感器。
6、避免低溫干擾:在擠出生產(chǎn)過程中,對于塑料原料而言,從固體到熔融狀態(tài)應(yīng)當(dāng)具有充足的“浸透時(shí)間”。如果擠出機(jī)在開始進(jìn)行生產(chǎn)前還沒有達(dá)到操作溫度,那么傳感器和擠出機(jī)都會(huì)受到一定程度的損壞。另外,如果傳感器從冷的擠出機(jī)上被拆除,材料就可能粘附在傳感器頂部引起震動(dòng)膜的損壞。因此,在拆除傳感器之前,應(yīng)確認(rèn)機(jī)筒的溫度足夠高,機(jī)筒內(nèi)部的物料處于軟化狀態(tài)下。
7、防止壓力過載:即使壓力傳感器測壓范圍的過載設(shè)計(jì)zui高能夠達(dá)到50%(超出zui大量程的比率),從設(shè)備運(yùn)行的安全角度考慮也應(yīng)該盡量避免冒險(xiǎn),選擇被測壓力處于量程范圍之內(nèi)的傳感器。在通常情況下,所選傳感器的*量程應(yīng)該是被測壓力的2倍,這樣即使擠出機(jī)在*的壓力下運(yùn)行,也能避免壓力傳感器受到損壞。 壓力變送器要求每周檢查一次,每個(gè)月檢驗(yàn)一次,主要是清除儀器內(nèi)的灰塵,對電器元件認(rèn)真檢查,對輸出的電流值要經(jīng)常校對,壓力變送器內(nèi)部是弱電,一定要同外界強(qiáng)電隔開。
