不同類型壓力變送器使用注意事項(xiàng)： </p> <p> 壓力變送器經(jīng)過長(zhǎng)期的市場(chǎng)應(yīng)用和技術(shù)研發(fā)，其成員不斷擴(kuò)大。針對(duì)一些特定使用場(chǎng)合的壓力變送器越來越多。這符合整個(gè)變送器行業(yè)發(fā)展細(xì)分化的需求，河北設(shè)備級(jí)壓力變送器介紹。不同類型的壓力變送器不僅在特點(diǎn)上有差異，在注意事項(xiàng)上也是有一定的區(qū)別的。向大家講解一下特殊類型壓力變送器的一些使用注意事項(xiàng)。 </p> <p> 高溫型壓力變送器：在使用過程中注意不要讓介質(zhì)溫度超過壓力變送器的工作溫度。必要時(shí)，需加裝冷卻裝置（冷凝管，河北設(shè)備級(jí)壓力變送器介紹、盤管），河北設(shè)備級(jí)壓力變送器介紹。 </p> <p> 防爆型壓力變送器：本安防爆型壓力變送器必須配備安全柵和本安電源才可在危險(xiǎn)場(chǎng)所使用。 </p> <p> 防水型壓力變送器：為了抵消大氣壓力，線纜內(nèi)部配有導(dǎo)氣管，產(chǎn)品接線處必須保障干燥通風(fēng)。 </p> <p> 衛(wèi)生型壓力變送器：衛(wèi)生型壓力變送器底部膜片采用的是無近壓孔、無腔平面結(jié)構(gòu)。需要注意壓力變送器的膜片非常脆弱，千萬不能用外物碰觸！膜片變形可以導(dǎo)致測(cè)量誤差不準(zhǔn)確，如膜片損壞壓力變送器則無法使用。一般意義上的壓力變送器主要由測(cè)壓元件傳感器（也稱作壓力傳感器）、測(cè)量電路和過程連接件三部分組成。河北設(shè)備級(jí)壓力變送器介紹</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河北設(shè)備級(jí)壓力變送器介紹,壓力變送器"

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?，直接影響差壓變送器選擇的類型不同。 </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 /> 河北高溫型壓力變送器廠家供應(yīng)在壓力變送器的線性范圍內(nèi)，變送器的靈敏度越高越好，有利于信號(hào)處理。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河北設(shè)備級(jí)壓力變送器介紹,壓力變送器" src="https://tyunfile.71360.com/UploadFile/xalunqian/637328439832978516/8960542.png"></div><p> 選擇怎樣的勵(lì)磁電壓：輸出信號(hào)的類型決定選擇怎么樣的勵(lì)磁電壓。許多放大變送器有內(nèi)置的電壓調(diào)節(jié)裝置，因此其電源電壓范圍較大。有些奕送器是定量配置，需要一個(gè)穩(wěn)定的工作電壓，因此，能夠得到的一個(gè)工作電壓決定是否采用帶有調(diào)節(jié)器的傳感器，選擇傳送器時(shí)要綜合考慮工作電壓與系統(tǒng)造價(jià)。 </p> <p> 是否需要具備互換性的變送器：確定所需的變送器是否能夠適應(yīng)多個(gè)使用系統(tǒng)。一般來講，這一點(diǎn)很重要。如果產(chǎn)品具有良好的互換性，那么即使是改變所用的變送器，也不會(huì)影響整個(gè)系統(tǒng)的效果。 </p> <p> 變送器超時(shí)工作后需要保持穩(wěn)定度：大部分變送器在經(jīng)過超時(shí)工作后會(huì)產(chǎn)生“漂移”，因此很有必要在購(gòu)買前了解變送器的穩(wěn)定度，這種預(yù)先的工作能減少將來使用中會(huì)出現(xiàn)的種種麻煩。 </p> <p> 變送器的封裝：變送器的封裝，尤其往往容易忽略是它的機(jī)架，然而這一點(diǎn)在以后使用中會(huì)逐漸暴露出其缺點(diǎn)。在選購(gòu)傳送器傳一定要考慮到將來變送器的工作環(huán)境，濕度如何，怎樣安裝變送器，會(huì)不會(huì)有強(qiáng)烈的撞擊或振動(dòng)等。 </p> <p> 在變送器與其它電子設(shè)備間采用怎樣的連接：是否需要采用短距離連接？若是采用長(zhǎng)距離連接，是否需要采用一個(gè)連接器？ </p> <p> <br /> </p>壓力變送器根據(jù)原理與結(jié)構(gòu)的不同，有著千差萬別的類型，怎樣通過實(shí)際的測(cè)量目的、測(cè)量對(duì)象和測(cè)量環(huán)境合理地選擇壓力變送器，這是我們?cè)谶M(jìn)行壓力測(cè)量時(shí)，首先要考慮的因素。只有確定好壓力變送器之后，才能更好的確定配套測(cè)量方法和測(cè)量設(shè)備的選擇。極大的保障了整個(gè)測(cè)量系統(tǒng)的合理應(yīng)用。 <p> 根據(jù)測(cè)量對(duì)象與測(cè)量環(huán)境確定壓力變送器的類型。 </p> <p> 選擇壓力變送器進(jìn)行具體的測(cè)量工作時(shí)，首先要進(jìn)行綜合分析，對(duì)比哪種壓力變送器更為合適。這就需要根據(jù)被測(cè)量的特點(diǎn)和壓力變送器的使用條件分析。 </p> <p> 要解決以下一些具體問題： </p> <p> 量程的大??；被測(cè)位置對(duì)變送器體積的要求；測(cè)量方式為接觸式還是非接觸式；信號(hào)的引出方法，有線或是無線；元器件的來源，國(guó)產(chǎn)還是進(jìn)口，價(jià)格能否承受等因素。 </p> <p> 以上這些因素我們的現(xiàn)場(chǎng)使用實(shí)際是什么樣的，就選擇相對(duì)應(yīng)的壓力變送器形式。這個(gè)是比較好選擇和控制的。用戶根據(jù)自己的現(xiàn)場(chǎng)進(jìn)行選擇就好。這就是我們對(duì)壓力變送器選用的第一步。做好這一步我們才能進(jìn)行接下來具體性能參數(shù)的選擇。壓力變送器的測(cè)量介質(zhì)一定要與其材質(zhì)兼容，一旦發(fā)現(xiàn)不兼容須馬上更換壓力變送器。</p><div

</p> <p> 固定銅片： </p> <p> 在技術(shù)較為成熟、品質(zhì)較好的壓力變送器產(chǎn)品中，都會(huì)在內(nèi)部添加固定銅片。固定銅片能夠很好的提高絕緣度、抗震性和接地穩(wěn)定性。部分廉價(jià)壓力變送器為節(jié)約成本則不會(huì)添加固定銅片。 </p> <p> 集成芯片： </p> <p> 集成芯片的品質(zhì)能夠很好的保障壓力變送器的抗干擾性和穩(wěn)定性。良好壓力變送器的集成芯片都是采用國(guó)際先進(jìn)的集成芯片，散件拼裝的電路芯片抗干擾性差，穩(wěn)定性差。 </p> <p> 隔離環(huán)： </p> <p> 壓力變送器添加隔離環(huán)能夠提高產(chǎn)品的絕緣度，對(duì)壓力變送器起到很好的保護(hù)作用。 </p> <p> 擴(kuò)散硅芯體： </p> <p> 先進(jìn)的壓力變送器采用進(jìn)口國(guó)際先進(jìn)硅晶圓擴(kuò)散硅芯體，這是壓力變送器高精度高、長(zhǎng)期穩(wěn)定性的保障。壓力變送器的價(jià)格差別主要體現(xiàn)在這個(gè)上邊。劣質(zhì)芯體長(zhǎng)期穩(wěn)定性差，也不能保證壓力變送器的測(cè)量精度。 </p> <p> 阻尼： </p> <p> 在壓力變送器內(nèi)部添加阻尼，為的是提高其抗沖擊的性能，更好的對(duì)壓力變送器內(nèi)部其他結(jié)構(gòu)進(jìn)行防護(hù)，避免瞬間的過壓對(duì)壓力變送器造成沖擊損壞。起到很好的保護(hù)作用。 </p> <p> <br /> </p> <p> <br /> 壓力變送器是一種接受壓力變量,經(jīng)傳感轉(zhuǎn)換后,將壓力變化量按一定比例轉(zhuǎn)換為標(biāo)準(zhǔn)輸出信號(hào)的儀表。河北設(shè)備級(jí)壓力變送器介紹</p><p style="text-indent:25px">不管什么型號(hào)的差壓變送器，其正、負(fù)壓室都有排氣、排液閥或旋塞;這為我們現(xiàn)場(chǎng)校準(zhǔn)差壓變送器提供了方便。河北設(shè)備級(jí)壓力變送器介紹</p><p> 防爆型壓力變送器介紹： </p> <p> 防爆型壓力變送器是通過被測(cè)的氣體或者液體的施壓，使得防爆壓力變送器的電阻值發(fā)生變化（電阻效應(yīng)），將測(cè)量的相對(duì)應(yīng)的信號(hào)轉(zhuǎn)化成相對(duì)應(yīng)的4~20mA輸出信號(hào)或者帶HART協(xié)議的數(shù)字信號(hào)以進(jìn)行通訊。防爆型壓力變送器安全防爆，可廣泛應(yīng)用于石化、電力、冶金、制藥、食品加工等行業(yè)。 </p> <p> 防爆型壓力變送器應(yīng)用的性危險(xiǎn)場(chǎng)所可分為0區(qū)、1區(qū)和2區(qū)。所謂0區(qū)是指在正常情況下，性氣體混合物連續(xù)的或長(zhǎng)時(shí)間地存在的場(chǎng)所；1區(qū)是指在正常情況下，性氣體混合物有可能出現(xiàn)的場(chǎng)所，2區(qū)指的是在正常情況下，性氣體不可能出現(xiàn)或即使出現(xiàn)也只是短暫時(shí)間存在的場(chǎng)所。對(duì)于防爆型壓力變送器來說，對(duì)0區(qū)的防爆要求是為嚴(yán)格的。壓力變送器可以是本安型、隔爆型，需要注意的是，不管什么形式的防爆型壓力變送器，均需要有國(guó)家防爆檢測(cè)部門的核實(shí)、取得相關(guān)防爆證書方可使用。 </p> <p> 防爆型壓力變送器中本安型需要配合安全柵才能在有性混合物的危險(xiǎn)場(chǎng)所使用。安全柵是靠控制能量來達(dá)到防爆規(guī)定的。本質(zhì)安全型防爆壓力變送器為了安全起見，應(yīng)區(qū)別本質(zhì)安全回路及非本質(zhì)安全回路，把本質(zhì)安全回路的接線與其它的電氣回路的接線分開走線。河北設(shè)備級(jí)壓力變送器介紹</p></p><br
