擴(kuò)散硅壓力變送器是在單晶硅片上擴(kuò)散一個(gè)惠斯通電橋，當(dāng)被測(cè)介質(zhì)的壓力直接作用于變送器的擴(kuò)散硅膜片上，使得變送器的膜片產(chǎn)生與介質(zhì)壓力成正比的微小位移。正常工作狀態(tài)下，膜片較大位移不大于0.025毫米，這時(shí)擴(kuò)散硅壓力變送器的橋壁電阻值發(fā)生變化，會(huì)產(chǎn)生一個(gè)差動(dòng)電壓信號(hào)，這一信號(hào)經(jīng)過(guò)**放大器，將量程相對(duì)應(yīng)的信號(hào)轉(zhuǎn)換輸出一個(gè)標(biāo)準(zhǔn)的模擬信號(hào)或數(shù)字信號(hào)。 </p> <p> 硅的電阻率對(duì)壓力有較高的敏感度，現(xiàn)在普遍使用硅材料作壓力變送器，也就是擴(kuò)散硅壓力變送器。擴(kuò)散硅是制造壓力變送器的中心部件，被封裝在316L不銹鋼的材料之中，外加施壓通過(guò)不銹鋼膜片、內(nèi)部密封的硅油傳遞到敏感的芯片上，擴(kuò)散硅敏感元件不直接接觸被測(cè)介質(zhì)，形成壓力測(cè)量的全固態(tài)結(jié)構(gòu)，使得擴(kuò)散硅壓力變送器能夠應(yīng)用更多的工況場(chǎng)合。 </p> <p> 擴(kuò)散硅壓力變送器作為一種高性能的壓力測(cè)量產(chǎn)品，可以很方便地進(jìn)行放大處理，裝配成標(biāo)準(zhǔn)信號(hào)輸出。擴(kuò)散硅壓力變送器廣泛應(yīng)用于石油、化工、冶金、電力、航空、醫(yī)療設(shè)備、汽車等行業(yè)的過(guò)程控制。擴(kuò)散硅壓力芯體外加氟橡膠O型圈進(jìn)行可靠密封。擴(kuò)散硅壓力變送器具有結(jié)構(gòu)小巧、安裝方便，抗干擾強(qiáng)、精度高、穩(wěn)定性好、響應(yīng)速度快、耐沖擊等特點(diǎn)。寧夏無(wú)線壓力變送器介紹壓力變送器的使用溫度是-40～85℃，但實(shí)際使用時(shí)比較好在-20~70℃以內(nèi)。</p><div

第一步：差壓變送器量程；不管我們選擇什么樣的差壓變送器，先要確認(rèn)的就是差壓量程、單端靜壓。因?yàn)榱砍痰牟町悾苯佑绊懖顗鹤兯推鬟x擇的類型不同。 </p> <p> 第二步：差壓變送器所處環(huán)境；影響差壓變送器的環(huán)境因素有兩個(gè)，一是環(huán)境溫度和濕度，二是現(xiàn)場(chǎng)干擾情況。差壓變送器對(duì)溫度和濕度都是有嚴(yán)格要求的。像是室內(nèi)環(huán)境中應(yīng)用的差壓變送器，選擇變送器環(huán)境溫度在-40～85℃之間，環(huán)境濕度在0%～95%RH之間即可。在戶外使用或超過(guò)上述范圍、現(xiàn)場(chǎng)有雨水或露水淋濺時(shí)，就要考慮用價(jià)格更貴的3051型差壓變送器。 </p> <p> 第三步：差壓變送器被測(cè)介質(zhì)；差壓變送器實(shí)際測(cè)量的介質(zhì)必須要與變送器接觸材質(zhì)兼容。以免損壞或腐蝕變送器元器件。 </p> <p> 第四步：差壓變送器的防爆性；防爆參數(shù)是差壓變送器的一個(gè)重要技術(shù)參數(shù)，現(xiàn)場(chǎng)有防爆要求的必須采用防爆型差壓變送器。防爆的類型也有所不同，有本安防爆、隔離防爆、粉塵防爆等不同要求。 </p> <p> 第五步：差壓變送器的顯示功能：因具體使用需求的差別，需不需要差壓變送器的顯示功能，也是要進(jìn)行選擇的。帶顯示差壓變送器能實(shí)時(shí)監(jiān)測(cè)差壓的測(cè)量值，當(dāng)然，帶顯示的價(jià)格會(huì)比不帶顯示的高一些。 </p> <p> <br /> </p><p> 防爆型壓力變送器選用高精度、高穩(wěn)定性和高可靠性的擴(kuò)散硅壓力傳感元件及進(jìn)口質(zhì)量集成電路，是一種精度高、可靠、穩(wěn)定性好、使用奉命長(zhǎng)的工業(yè)用壓力變送器，用于測(cè)量液體或氣體的壓力及各種液體的液位．并把壓力或液位轉(zhuǎn)換成標(biāo)準(zhǔn)電信號(hào)的現(xiàn)場(chǎng)遠(yuǎn)傳壓力及液位測(cè)量?jī)x表。防爆壓力變送器，因其優(yōu)良的性能，可代替進(jìn)口gaodang次的壓力變送器，用于計(jì)量或測(cè)控精度要求高的場(chǎng)合，可具有防爆特性，耐沖擊性能好。應(yīng)用范圍：工業(yè)現(xiàn)場(chǎng)過(guò)程壓力控制航空航天領(lǐng)域石油化工輕工機(jī)械醫(yī)療設(shè)備航海造船行業(yè)水利水電發(fā)電廠恒壓供水其它自動(dòng)化控制和檢測(cè)系統(tǒng)產(chǎn)品特點(diǎn)：測(cè)量范圍廣:,0-(10KPa-60MPa)零點(diǎn)、量程連續(xù)可調(diào)具有反向極性保護(hù)及限流保護(hù)耐沖擊性能突出高精度、高穩(wěn)定性、高可靠性IP65外殼防護(hù)等級(jí)，適于戶外安裝可具有防爆特性，適用于要求高的場(chǎng)合，符合計(jì)量標(biāo)準(zhǔn)要求獨(dú)特的設(shè)計(jì)使防水錘沖擊性能好使用奉命長(zhǎng)根據(jù)特殊要求，可使之具有良好的抗結(jié)冰性能。壓力變送器測(cè)得就是管道內(nèi)的實(shí)際壓力若不確定可以將壓力變送器切出來(lái)對(duì)大氣，壓力幾乎為零則說(shuō)明測(cè)量正確。</p><div

差壓變送器是有固定量程范圍的，在量程范圍內(nèi)使用，差壓變送器性能才是正常的。在現(xiàn)場(chǎng)使用過(guò)程中，如果出現(xiàn)超量程的現(xiàn)象。這時(shí)候要怎么對(duì)差壓變送器進(jìn)行排查呢？ </p> <p> 1、根據(jù)控制室趨勢(shì)圖進(jìn)行分析故障原因，排查是否因工藝原因造成的壓力值偏差，誤判斷為儀表問(wèn)題。如果為工藝原因，趨勢(shì)指示與壓力示值程緩慢變化趨勢(shì)，或根據(jù)工況有規(guī)律變化，如果是儀表問(wèn)題，一般趨勢(shì)圖不程緩慢變化，變化幅度非常劇烈。2、如處理故障為超量程，首先對(duì)其進(jìn)行斷電，而后在送電進(jìn)行觀察，如果故障顯示仍然為超量程，那么測(cè)量一下電流值是否對(duì)應(yīng)其指示壓力值。3、參照比較差壓變送器現(xiàn)場(chǎng)顯示壓力，與就地指示壓力表顯示的壓力值進(jìn)行比較，并確認(rèn)測(cè)量管道是否有余壓。4、對(duì)差壓變送器進(jìn)行一次到兩次機(jī)械零點(diǎn)調(diào)整，故障仍然顯示為超量程，那么就要考慮是否為儀表本身的故障。5、差壓變送器自身故障情況分為兩種。情況一：變送器3大模塊有故障，情況二：變送器感壓膜片變形。6、如果差壓變送器在更換模塊后故障仍為超量程，那么終情況即為差壓變送器感壓膜片變形或者損壞。變送器當(dāng)兩側(cè)壓力不一致時(shí)，壓力變送器和***壓力變送器的工作原理和差壓變送器相同。水暖管道壓力變送器性能</p><p

壓力變送器與差壓變送器的相同點(diǎn)： </p> <p> 工作原理相同：壓力變送器與差壓變送器都是通過(guò)壓阻效應(yīng)產(chǎn)生的電壓信號(hào)，經(jīng)過(guò)放大、零點(diǎn)和靈敏度溫度補(bǔ)償來(lái)實(shí)現(xiàn)其終的測(cè)量。 </p> <p> 輸出信號(hào)相同：不管是壓力變送器還是差壓變送器，都能進(jìn)行4～20 mA 的電流輸出、RS485 數(shù)字信號(hào)輸出和0～10 VDC、0～5 VDC等電壓信號(hào)輸出。 </p> <p> 壓力變送器與差壓變送器的不同點(diǎn)： </p> <p> 壓力端的不同：壓力變送器只能測(cè)量一個(gè)壓力端的壓力，而差壓變送器可以測(cè)量?jī)蓚€(gè)壓力點(diǎn)的壓力，兩者壓力相減，正壓端壓力減負(fù)壓端壓力得出壓力差值。 </p> <p> 連接方式的不同：壓力變送器一般采用的都是螺紋連接，差壓變送器除了可采用螺紋連接，更多的則選用寶塔嘴和快接口的連接方式，可直接接相應(yīng)直徑的軟管。安裝更加方便。水暖管道壓力變送器性能</p><p
