情況一：壓力變送器采用的是帶顯示的表頭，那么供電電壓zui好選擇15～36V DC，因為壓力變送器的表頭也是需要一定的供給。 </p> <p> 情況二：如果我們的壓力變送器輸出信號為0.5～2.5V DC的輸出信號或者采用RS485輸出信號時，壓力變送器的供電電壓應(yīng)定制3～5V DC。 </p> <p> 情況三:如果我們采用的是防爆型壓力變送器本安防爆型或粉塵本質(zhì)安全型，壓力變送器的供電電壓就需要選用本安電源24V DC。 </p> <p>

怎樣避免壓力變送器使用中的誤差:因為壓力變送器使用過程中的誤操作，會使得壓力變送器的測量結(jié)果產(chǎn)生誤差。壓力變送器測量誤差的大小，終將影響到整個測控系統(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)場的導(dǎo)壓管盡可能短些;方法二：當壓力變送器測量液體或蒸汽時，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：壓力變送器對于氣體測量時，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，氣體導(dǎo)壓管的布設(shè)要避免中間出現(xiàn)低點;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：當使用隔離液時，兩邊導(dǎo)壓管的液體要相同;方法九：采用潔凈劑時，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。甘肅數(shù)顯壓力變送器擴散硅壓力變送器具有工作可靠、性能穩(wěn)定、安裝使用方便、體積小、重量輕、性能價格比高等特點。</p><div

<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。部分廉價壓力變送器為節(jié)約成本則不會添加固定銅片。 </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際先進的集成芯片，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，對壓力變送器起到很好的保護作用。 </p> <p> 擴散硅芯體： </p> <p> 先進的壓力變送器采用進口國際先進硅晶圓擴散硅芯體，這是壓力變送器高精度高、長期穩(wěn)定性的保障。壓力變送器的價格差別主要體現(xiàn)在這個上邊。劣質(zhì)芯體長期穩(wěn)定性差，也不能保證壓力變送器的測量精度。 </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，更好的對壓力變送器內(nèi)部其他結(jié)構(gòu)進行防護，避免瞬間的過壓對壓力變送器造成沖擊損壞。起到很好的保護作用。 </p> <p> <br /> </p> <p> <br /> </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)），將測量的相對應(yīng)的信號轉(zhuǎn)化成相對應(yīng)的4~20mA輸出信號或者帶HART協(xié)議的數(shù)字信號以進行通訊。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)用的性危險場所可分為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)的或長時間地存在的場所；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)也只是短暫時間存在的場所。對于防爆型壓力變送器來說，對0區(qū)的防爆要求是為嚴格的。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，均需要有國家防爆檢測部門的核實、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場所使用。安全柵是靠控制能量來達到防爆規(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。變送器高頻噪聲通過變壓器主要不是靠初、次級線圈的互感耦合，而是靠初、次級寄生電容耦合的。</p><div

測量范圍：在允許誤差限內(nèi)被測量值的范圍稱為測量范圍。 </p> <p> 上限值：測量范圍的比較高值稱為測量范圍的上限值。 </p> <p> 下限值：測量范圍的比較低值稱為測量范圍的下限值。 </p> <p> 量程：測量范圍的上限值和下限值的代數(shù)差就是量程。 </p> <p> 精度：被測量的測量結(jié)果與真值間的一致程度。 </p> <p>

通用型壓力變送器采用壓阻式壓力傳感器。壓阻式傳感器是壓力式傳感器的一種。壓阻式壓力傳感器又稱擴散硅壓力傳感器。壓阻式壓力變送器,傳感器信號經(jīng)過信號處理電路后轉(zhuǎn)換為標準信號輸出，產(chǎn)品經(jīng)過了長期老化及穩(wěn)定性考核等工藝嚴格篩選，性能穩(wěn)定可靠。應(yīng)用于環(huán)境比較惡劣的露天現(xiàn)場，同時要求能夠現(xiàn)場觀測壓力顯示、需要零點遷移和量程調(diào)節(jié)的場合。應(yīng)用領(lǐng)域：適用于石油、化工、冶金、電力、輕工、紡織、建材、水文地質(zhì)、食品、醫(yī)藥、環(huán)境控制等行業(yè)的過程控制和壓力測量。 </p> <p> 水壓變送器擴散硅跟電容變送器的對比:根本區(qū)別在于基礎(chǔ)檢出信號不同。以及相應(yīng)的電路和構(gòu)造不同;電容式變送器的基礎(chǔ)信號是電容量；擴散硅變送器的基礎(chǔ)信號是電阻值;電容式在壓力作用下敏感元件的膜片發(fā)生位移，導(dǎo)致膜片與相鄰電極構(gòu)成的電容量發(fā)生變化而檢出壓力；擴散硅在壓力作用下敏感元件的膜片發(fā)生位移，產(chǎn)生的力作用在擴散硅材料商，使擴散硅的阻值變化而檢出壓力;電容式利用的是物理性質(zhì)，所以主要受制造水平的限制；擴散硅利用的是材料的物理性質(zhì)，所以受材料影響較大;擴散硅在體積、價格上有優(yōu)勢；但受擴散硅材料的穩(wěn)定性影響，壽命的精度較差。吉林無線遠傳壓力變送器哪里買</p><p
