高溫熔體壓力傳感器主要在高溫流體介質中的壓力測量和控製，主要應用於橡塑機械、聚酯等設備，可見在其中的重要作用。因此正確的使用和維護便成了工作人員熟知的操作。

　　檢查安裝孔的尺寸

　　如(ru)果(guo)安(an)裝(zhuang)孔(kong)的(de)尺(chi)寸(cun)不(bu)合(he)適(shi)
，高(gao)溫(wen)熔(rong)體(ti)壓(ya)力(li)傳(chuan)感(gan)器(qi)在(zai)安(an)裝(zhuang)過(guo)程(cheng)中(zhong)，其(qi)螺(luo)紋(wen)部(bu)分(fen)就(jiu)很(hen)容(rong)易(yi)受(shou)到(dao)磨(mo)損(sun)。這(zhe)不(bu)僅(jin)會(hui)影(ying)響(xiang)設(she)備(bei)的(de)密(mi)封(feng)性(xing)能(neng)，而(er)且(qie)使(shi)傳(chuan)感(gan)器(qi)不(bu)能(neng)充(chong)分(fen)發(fa)揮(hui)作(zuo)用(yong)，甚(shen)至(zhi)還(hai)可(ke)能(neng)產(chan)生(sheng)安(an)全(quan)隱(yin)患(huan)。隻(zhi)有(you)合(he)適(shi)的(de)安(an)裝(zhuang)孔(kong)才(cai)能(neng)夠(gou)避(bi)免(mian)螺(luo)紋(wen)的(de)磨(mo)損(sun)(螺紋工業標準1/2-20UNF2B)，通常可以采用安裝孔測量儀對安裝孔進行檢測，以做出適當的調整。

　　選擇恰當的位置

　　當高溫熔體壓力傳感器的安裝位置太靠近生產線的上遊時
，未熔融的物料可能會磨損傳感器的頂部;如ru果guo高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi被bei安an裝zhuang在zai太tai靠kao後hou的de位wei置zhi
，在zai高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi和he螺luo杆gan行xing程cheng之zhi間jian可ke能neng會hui產chan生sheng熔rong融rong物wu料liao的de停ting滯zhi區qu，熔rong料liao在zai那na裏li有you可ke能neng產chan生sheng降jiang解jie，壓ya力li信xin號hao也ye可ke能neng傳chuan遞di失shi真zhen;如ru果guo高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi過guo於yu深shen入ru機ji筒tong，螺luo杆gan有you可ke能neng在zai旋xuan轉zhuan過guo程cheng中zhong觸chu碰peng到dao高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi的de頂ding部bu而er造zao成cheng其qi損sun壞huai。一yi般ban來lai說shuo
，高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi可ke以yi位wei於yu濾lv網wang前qian麵mian的de機ji筒tong上shang、熔體泵的前後或者模具中。

　　避免低溫幹擾

　　在擠出生產過程中，對於塑料原料而言，從固體到熔融狀態應當具有充足的“浸透時間”。如ru果guo擠ji出chu機ji在zai開kai始shi進jin行xing生sheng產chan前qian還hai沒mei有you達da到dao操cao作zuo溫wen度du，那na麼me高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi和he擠ji出chu機ji都dou會hui受shou到dao一yi定ding程cheng度du的de損sun壞huai。另ling外wai

，如ru果guo高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi從cong冷leng的de擠ji出chu機ji上shang被bei拆chai除chu，材cai料liao就jiu可ke能neng粘zhan附fu在zai高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi頂ding部bu引yin起qi震zhen動dong膜mo的de損sun壞huai。因yin此ci

，在zai拆chai除chu高gao溫wen熔rong體ti壓ya力li傳chuan感gan器qi之zhi前qian，應ying確que認ren機ji筒tong的de溫wen度du足zu夠gou高gao，機ji筒tong內nei部bu的de物wu料liao處chu於yu軟ruan化hua狀zhuang態tai下xia。

　　仔細清潔

　　在(zai)使(shi)用(yong)鋼(gang)絲(si)刷(shua)或(huo)者(zhe)特(te)殊(shu)化(hua)合(he)物(wu)對(dui)擠(ji)出(chu)機(ji)機(ji)筒(tong)進(jin)行(xing)清(qing)潔(jie)前(qian)，應(ying)該(gai)將(jiang)所(suo)有(you)的(de)高(gao)溫(wen)熔(rong)體(ti)壓(ya)力(li)傳(chuan)感(gan)器(qi)都(dou)拆(chai)卸(xie)下(xia)來(lai)。因(yin)為(wei)這(zhe)兩(liang)種(zhong)清(qing)潔(jie)方(fang)式(shi)都(dou)可(ke)能(neng)會(hui)造(zao)成(cheng)高(gao)溫(wen)熔(rong)體(ti)壓(ya)力(li)傳(chuan)感(gan)器(qi)的(de)震(zhen)動(dong)膜(mo)受(shou)損(sun)。當(dang)機(ji)筒(tong)被(bei)加(jia)熱(re)時(shi)，也(ye)應(ying)該(gai)將(jiang)高(gao)溫(wen)熔(rong)體(ti)壓(ya)力(li)傳(chuan)感(gan)器(qi)拆(chai)卸(xie)下(xia)來(lai)並(bing)使(shi)用(yong)不(bu)會(hui)產(chan)生(sheng)磨(mo)損(sun)的(de)軟(ruan)布(bu)來(lai)擦(ca)拭(shi)其(qi)頂(ding)部(bu)，同(tong)時(shi)高(gao)溫(wen)熔(rong)體(ti)壓(ya)力(li)傳(chuan)感(gan)器(qi)的(de)孔(kong)洞(dong)也(ye)需(xu)要(yao)用(yong)清(qing)潔(jie)的(de)鑽(zuan)孔(kong)機(ji)和(he)導(dao)套(tao)清(qing)理(li)幹(gan)淨(jing)。

　　保持幹燥

　　盡(jin)管(guan)高(gao)溫(wen)熔(rong)體(ti)壓(ya)力(li)傳(chuan)感(gan)器(qi)的(de)電(dian)路(lu)設(she)計(ji)能(neng)夠(gou)經(jing)受(shou)苛(ke)刻(ke)的(de)擠(ji)出(chu)加(jia)工(gong)環(huan)境(jing)，但(dan)是(shi)多(duo)數(shu)高(gao)溫(wen)熔(rong)體(ti)壓(ya)力(li)傳(chuan)感(gan)器(qi)也(ye)不(bu)能(neng)絕(jue)對(dui)防(fang)水(shui)，在(zai)潮(chao)濕(shi)的(de)環(huan)境(jing)下(xia)也(ye)不(bu)利(li)於(yu)正(zheng)常(chang)運(yun)行(xing)。因(yin)此(ci)

，需(xu)要(yao)保(bao)證(zheng)擠(ji)出(chu)機(ji)機(ji)筒(tong)的(de)水(shui)冷(leng)裝(zhuang)置(zhi)中(zhong)的(de)水(shui)不(bu)會(hui)滲(shen)漏(lou)，否(fou)則(ze)會(hui)對(dui)傳(chuan)感(gan)器(qi)造(zao)成(cheng)不(bu)利(li)影(ying)響(xiang)。如(ru)果(guo)傳(chuan)感(gan)器(qi)不(bu)得(de)不(bu)暴(bao)露(lu)在(zai)水(shui)中(zhong)或(huo)潮(chao)濕(shi)的(de)環(huan)境(jing)下(xia)
，就(jiu)要(yao)選(xuan)擇(ze)具(ju)有(you)極(ji)強(qiang)防(fang)水(shui)性(xing)的(de)特(te)殊(shu)高(gao)溫(wen)熔(rong)體(ti)壓(ya)力(li)傳(chuan)感(gan)器(qi)。

　　防止壓力過載

　　即使傳感器測壓範圍的過載設計最高能夠達到50%(超出最大量程的比率)，congshebeiyunxingdeanquanjiaodukaolvyeyinggaijinliangbimianmaoxian，zuihaoxuanzebeiceyalichuyuliangchengfanweizhineidegaowenrongtiyalichuanganqi。zaitongchangqingkuangxia，suoxuangaowenrongtiyalichuanganqidezuijialiangchengyinggaishibeiceyalide2倍，這樣即使擠出機在極高的壓力下運行，也能避免高溫熔體壓力傳感器受到損壞。
