防爆型壓力變送器介紹： </p> <p> 防爆型壓力變送器是通過(guò)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(lái)說(shuō)，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)，陜西擴(kuò)散硅壓力變送器聯(lián)系方式、取得相關(guān)防爆證書(shū)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(lái)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(jiàn)，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(kāi)走線。擴(kuò)散硅壓力變送器具有工作可靠，陜西擴(kuò)散硅壓力變送器聯(lián)系方式、性能穩(wěn)定、安裝使用方便、體積小，陜西擴(kuò)散硅壓力變送器聯(lián)系方式、重量輕、性能價(jià)格比高等特點(diǎn)。陜西擴(kuò)散硅壓力變送器聯(lián)系方式</p><div

style="text-indent:25px">在選用壓力變送器之初，要對(duì)現(xiàn)場(chǎng)使用工況進(jìn)行分析，根據(jù)具體使用環(huán)境選擇適合的壓力變送器，還要采取適當(dāng)?shù)拇胧?，減少環(huán)境對(duì)壓力變送器的影響。壓力變送器穩(wěn)定性有定量指標(biāo)，在超過(guò)使用期后，需要重新進(jìn)行標(biāo)定，以確保壓力變送器的性能是否發(fā)生變化。在某些要求壓力變送器能長(zhǎng)期使用而又不能輕易更換或標(biāo)定的場(chǎng)合，所選用的壓力變送器穩(wěn)定性要求更嚴(yán)格，要能夠經(jīng)受住長(zhǎng)時(shí)間的考驗(yàn)。壓力變送器穩(wěn)定性有著重要的意義，選擇高穩(wěn)定性的壓力變送器是非常有必要的。在高穩(wěn)定性能這個(gè)基礎(chǔ)前提下，才能制造出具有高準(zhǔn)確度、高可靠性等能力的壓力變送器。壓力變送器穩(wěn)定性對(duì)于生產(chǎn)的正常運(yùn)行以及壽命的使用都有著重要的影響。陜西擴(kuò)散硅壓力變送器聯(lián)系方式壓力變送器的外殼是否有效、真實(shí)的接地。壓力變送器外殼有效接地，具有很好的抗干擾作用。</p><div

小巧型壓力變送器的技術(shù)參數(shù)：測(cè)量范圍:-100KPa~60MPa允許溫度介質(zhì)溫度:-30~85℃比較高可達(dá)200℃環(huán)境溫度:-30~80℃儲(chǔ)存溫度:-30~+80℃溫度影響:TK<±0.02±%FS/K精度等級(jí):0.2、0.5級(jí)工作電壓:12~36VDC工作溫度:-30~80℃輸出信號(hào):4~20mA(二線制)、1~5V(三線制)負(fù)載電阻:<=750Ω。 </p><p> 壓力變送器與差壓變送器的差異： </p> <p> 在工業(yè)自動(dòng)化來(lái)領(lǐng)域，壓力變送器與差壓變送器都是不可缺少的一種測(cè)量?jī)x表。我們就來(lái)分析一下壓力變送器和差壓變送器相同與不同之處。 </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。影響壓力變送器長(zhǎng)期穩(wěn)定性的因素除壓力變送器本身結(jié)構(gòu)外，還有就是變送器的使用環(huán)境。</p><div style="width:100%;text-align:
