1 正確安裝
通tong常chang壓ya力li傳chuan感gan器qi的de損sun壞huai都dou是shi由you於yu其qi安an裝zhuang位wei置zhi不bu恰qia當dang而er引yin起qi的de。如ru果guo將jiang傳chuan感gan器qi強qiang行xing安an裝zhuang在zai過guo小xiao的de孔kong或huo形xing狀zhuang不bu規gui則ze的de孔kong中zhong，就jiu有you可ke能neng造zao成cheng傳chuan感gan器qi的de震zhen動dong膜mo受shou到dao衝chong擊ji而er損sun壞huai。選xuan擇ze合he適shi的de工gong具ju加jia工gong安an裝zhuang孔kong，有you利li於yu控kong製zhi安an裝zhuang孔kong的de尺chi寸cun。另ling外wai，合he適shi的de安an裝zhuang扭niu矩ju有you利li於yu形xing成cheng良liang好hao的de密mi封feng。但dan是shi如ru果guo安an裝zhuang扭niu矩ju過guo高gao就jiu容rong易yi引yin起qi傳chuan感gan器qi的de滑hua脫tuo，為wei防fang止zhi這zhe種zhong現xian象xiang發fa生sheng，通tong常chang在zai傳chuan感gan器qi安an裝zhuang之zhi前qian在zai其qi螺luo紋wen部bu分fen上shang塗tu抹mo防fang脫tuo化hua合he物wu。在zai使shi用yong這zhe種zhong化hua合he物wu以yi後hou，即ji使shi安an裝zhuang扭niu矩ju很hen高gao，傳chuan感gan器qi也ye很hen難nan被bei移yi動dong。
2 檢查安裝孔的尺寸
ruguoanzhuangkongdechicunbuheshi，chuanganqizaianzhuangguochengzhong，qiluowenbufenjiuhenrongyishoudaomosun。zhebujinhuiyingxiangshebeidemifengxingneng，erqieshichuanganqibunengchongfenfahuizuoyong，shenzhihaikenengchanshenganquanyinhuan。zhiyouheshideanzhuangkongcainenggoubimianluowendemosun（螺紋工業標準1/2-20 UNF 2B），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。
3 保持安裝孔的清潔
保bao持chi安an裝zhuang孔kong的de清qing潔jie並bing防fang止zhi熔rong料liao堵du塞sai對dui保bao證zheng設she備bei的de正zheng常chang運yun行xing來lai說shuo十shi分fen重zhong要yao。在zai擠ji出chu機ji被bei清qing潔jie之zhi前qian，所suo有you的de傳chuan感gan器qi都dou應ying該gai從cong機ji筒tong上shang拆chai除chu以yi避bi免mian損sun壞huai。在zai拆chai除chu傳chuan感gan器qi時shi，熔rong料liao有you可ke能neng流liu入ru到dao安an裝zhuang孔kong中zhong並bing硬ying化hua，如ru果guo這zhe些xie殘can餘yu的de熔rong料liao沒mei有you被bei去qu除chu，當dang再zai次ci安an裝zhuang傳chuan感gan器qi時shi就jiu可ke能neng造zao成cheng其qi頂ding部bu受shou損sun。清qing潔jie工gong具ju包bao能neng夠gou將jiang這zhe些xie熔rong料liao殘can餘yu物wu去qu除chu。然ran而er，重zhong複fu的de清qing潔jie過guo程cheng有you可ke能neng加jia深shen安an裝zhuang孔kong對dui傳chuan感gan器qi造zao成cheng的de損sun壞huai。如ru果guo這zhe種zhong情qing況kuang發fa生sheng，就jiu應ying當dang采cai取qu措cuo施shi來lai升sheng高gao傳chuan感gan器qi在zai安an裝zhuang孔kong中zhong的de位wei置zhi。
4 選擇恰當的位置
當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)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)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)；如果傳感器過於深入機筒，螺杆有可能在旋轉過程中觸碰到傳感器的頂部而造成其損壞。一般來說，傳感器可以位於濾網前麵的機筒上、熔體泵的前後或者模具中。
5 保持幹燥

6 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。
7 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”。ruguojichujizaikaishijinxingshengchanqianhaimeiyoudadaocaozuowendu，namechuanganqihejichujidouhuishoudaoyidingchengdudesunhuai。lingwai，ruguochuanganqiconglengdejichujishangbeichaichu，cailiaojiukenengzhanfuzaichuanganqidingbuyinqizhendongmodesunhuai。yinci，zaichaichuchuanganqizhiqian，yingquerenjitongdewenduzugougao，jitongneibudewuliaochuyuruanhuazhuangtaixia。
8 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），從cong設she備bei運yun行xing的de安an全quan角jiao度du考kao慮lv也ye應ying該gai盡jin量liang避bi免mian冒mao險xian，最zui好hao選xuan擇ze被bei測ce壓ya力li處chu於yu量liang程cheng範fan圍wei之zhi內nei的de傳chuan感gan器qi。在zai通tong常chang情qing況kuang下xia，所suo選xuan傳chuan感gan器qi的de最zui佳jia量liang程cheng應ying該gai是shi被bei測ce壓ya力li的de2倍，這樣即使擠出機在極高的壓力下運行，也能避免傳感器受到損壞。
