在工業(yè)自動(dòng)化來領(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壓阻效應(yīng)產(chǎn)生的電壓信號(hào)，經(jīng)過放大、零點(diǎn)和靈敏度溫度補(bǔ)償來實(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。 </p><p> 怎樣避免壓力變送器使用中的誤差:因?yàn)閴毫ψ兯推魇褂眠^程中的誤操作，會(huì)使得壓力變送器的測(cè)量結(jié)果產(chǎn)生誤差。壓力變送器測(cè)量誤差的大小，終將影響到整個(gè)測(cè)控系統(tǒng)的性能。為大家總結(jié)整理了壓力變送器可能造成誤差的原因，并教大家一些減少和避免誤差的有效方法。 </p> <p> 造成誤差的原因：原因一：液體管路中有氣體;原因二：磨損損失;原因三：泄露;原因四：氣體管路中存有液體;原因五：兩邊導(dǎo)壓管之間因溫差引的密度不同. </p> <p> 減少誤差的方法：方法一：壓力變送器使用現(xiàn)場(chǎng)的導(dǎo)壓管盡可能短些;方法二：當(dāng)壓力變送器測(cè)量液體或蒸汽時(shí)，導(dǎo)壓管向上流連接到工藝管道，其斜度應(yīng)不小于1/12;方法三：壓力變送器對(duì)于氣體測(cè)量時(shí)，導(dǎo)壓管向下連接到工藝管道，其斜度應(yīng)不小于1/12;方法四：液體導(dǎo)壓管道的布設(shè)要避免中間出現(xiàn)高點(diǎn)，氣體導(dǎo)壓管的布設(shè)要避免中間出現(xiàn)低點(diǎn);方法五：兩導(dǎo)壓管之間應(yīng)保持相同溫度;方法六：為避免磨擦影響，導(dǎo)壓管的口徑應(yīng)足夠大;方法七：充滿液體的導(dǎo)壓管中應(yīng)無氣體存在;方法八：當(dāng)使用隔離液時(shí)，兩邊導(dǎo)壓管的液體要相同;方法九：采用潔凈劑時(shí)，潔凈劑連接處應(yīng)靠近工藝管道取壓口，潔凈劑所經(jīng)過的管路，其長度和口徑應(yīng)相同，應(yīng)避免潔凈劑通過壓力變送器。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

壓力變送器剛買回來使用，效果很好，可沒幾天就不能用了。其實(shí)壓力變送器在使用過程中，如果方法不當(dāng)，是會(huì)造成損壞的。壓力變送器的損壞，會(huì)對(duì)用戶造成很大的影響。接下來教大家如何正確使用壓力變送器避免其損壞。希望能夠幫助到大家。 </p> <p> 1：在壓力傳輸過程中，應(yīng)注意壓力變送器與散熱管連接處，切勿漏氣。管路中必須保持暢通，管道中的沉積物，極有可能損壞壓力變送器膜片。開始使用前如果閥門是關(guān)閉的，則使用時(shí)應(yīng)該非常小心緩慢地打開閥門，以免被測(cè)介質(zhì)直接沖擊壓力變送器膜片從而損壞膜片。2：測(cè)量蒸汽或其他高溫介質(zhì)時(shí)，應(yīng)使用散熱管。溫度不得超過壓力變送器使用溫度的極限。3：切勿用硬物碰觸膜片，導(dǎo)致壓力變送器隔離膜片損壞。4：被測(cè)介質(zhì)不允許結(jié)冰，否則將損傷壓力變送器元件，導(dǎo)致變送器損壞，必要時(shí)需對(duì)壓力變送器進(jìn)行溫度保護(hù)，以防結(jié)冰。5：切勿用高于36V電壓加到壓力變送器上，導(dǎo)致變送器損壞。還有，在使用安裝壓力變送器前，一定要仔細(xì)認(rèn)真閱讀說明書。多方位了解壓力變送器的各項(xiàng)信息。保證在合理合規(guī)的前提下，對(duì)壓力變送器進(jìn)行操作。壓力變送器以供給指示報(bào)警儀、記錄儀、調(diào)節(jié)器等二次儀表進(jìn)行測(cè)量、指示和過程調(diào)節(jié)。蒸汽管道壓力變送器介紹</p><p style="text-indent:25px">常規(guī)的壓力變送器輸出信號(hào)有4～20mA電流輸出、0～10VDC、0.5～2.5VDC等電壓輸出和RS485數(shù)字輸出信號(hào)。陜西小巧型壓力變送器哪家好</p><p> 差壓變送器的選購指南。 </p> <p> 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 /> 陜西小巧型壓力變送器哪家好</p></p><br /><p>文章來源地址:
