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(kuò)散硅壓力傳感器。壓阻式壓力變送器,傳感器信號(hào)經(jīng)過(guò)信號(hào)處理電路后轉(zhuǎn)換為標(biāo)準(zhǔn)信號(hào)輸出，產(chǎn)品經(jīng)過(guò)了長(zhǎng)期老化及穩(wěn)定性考核等工藝嚴(yán)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(chǎng)，同時(shí)要求能夠現(xiàn)場(chǎng)觀測(cè)壓力顯示、需要零點(diǎn)遷移和量程調(diào)節(jié)的場(chǎng)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(guò)程控制和壓力測(cè)量。 </p> <p> 水壓變送器擴(kuò)散硅跟電容變送器的對(duì)比:根本區(qū)別在于基礎(chǔ)檢出信號(hào)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(hào)是電容量；擴(kuò)散硅變送器的基礎(chǔ)信號(hào)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(kuò)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(kuò)散硅材料商，使擴(kuò)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(kuò)散硅利用的是材料的物理性質(zhì)，所以受材料影響較大;擴(kuò)散硅在體積、價(jià)格上有優(yōu)勢(shì)；但受擴(kuò)散硅材料的穩(wěn)定性影響，壽命的精度較差。經(jīng)濟(jì)型壓力變送器價(jià)格壓力變送器的測(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

在壓力變送器的使用過(guò)程中需要電源為其供電，通常情況下我們?nèi)粘Ｉ钪杏玫降碾妷簽?20V的交流電（AC），對(duì)于壓力變送器而言，需要連續(xù)輸出穩(wěn)定的信號(hào)，直流電(DC)在方向和大小上都是穩(wěn)定的，不會(huì)隨時(shí)間發(fā)生改變，交流電則恰恰相反。這就是大多數(shù)壓力變送器采用直流電的原因。錯(cuò)誤的選擇壓力變送器的供電電壓，會(huì)損壞壓力變送器的電路板，這也是導(dǎo)致壓力變送器出現(xiàn)故障的主要原因之一。采用多大的供電電壓是壓力變送器的一個(gè)重要的問(wèn)題。 </p> <p> 壓力變送器的常規(guī)供電電壓為12～36V DC,采用此范圍的供電電壓可以有效的避免因電壓過(guò)高造成損壞，選擇此范圍的供電電壓也比較符合現(xiàn)在主流設(shè)備，方便壓力變送器與其它設(shè)備系統(tǒng)進(jìn)行對(duì)接、組合使用。習(xí)慣上24V DC的供電電壓用在壓力變送器中應(yīng)用的比較多， 24V DC能夠適應(yīng)大多數(shù)傳輸和負(fù)載需求（帶 250Ω×2個(gè)負(fù)載和 1KM 傳輸距離），高了浪費(fèi)低了應(yīng)用受限制，當(dāng)然如果有需要完全可以改變供電電壓。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> 但是過(guò)載能力也有一個(gè)度，一般是150%的范圍內(nèi)，（星儀壓力變送器的過(guò)載能力能達(dá)到滿量程的200%或者是120MPa。）使得壓力變送器在瞬間環(huán)境影響造成的超量程中，也能免受損壞，保護(hù)芯體等元器件不被燒毀等。對(duì)我們的壓力變送器起到很好的保護(hù)作用。 </p> <p> 過(guò)載能力是每種壓力變送器都要考慮的，因?yàn)樵趬毫ψ兯推鞯氖褂眠^(guò)程中，很有可能會(huì)出現(xiàn)測(cè)量值大于量程的情況，只有設(shè)計(jì)了過(guò)載保護(hù)的變送器才能更好的使用，也才能使用得更久。所以不管是買什么類型的壓力變送器，一定要了解它的過(guò)載能力是多少，這樣才能更好的方便使用，在未來(lái)使用過(guò)程中也不會(huì)出現(xiàn)由于過(guò)載燒壞電路的情況。 </p> <p> 在這里也要提醒大家這是個(gè)瞬間造成過(guò)載的保護(hù)措施，我們?cè)谶x購(gòu)壓力變送器時(shí)，還是要對(duì)量程范圍作出精確的判斷，這是壓力變送器長(zhǎng)期穩(wěn)定工作的基礎(chǔ)。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

src="https://tyunfile.71360.com/UploadFile/xalunqian/637328438789843750/8741677.png"></div><p> 壓力變送器與液位傳感器是各類設(shè)備中或項(xiàng)目中經(jīng)常遇到的兩類傳感器，下面來(lái)了解壓力變送器與液位傳感器兩者的區(qū)別? </p> <p> 1、壓力傳感器和液位傳感器的測(cè)量原理，都是將傳感器投入被測(cè)液體設(shè)定深度，傳感器測(cè)量點(diǎn)直接接觸液面受到的壓力公式為：Ρ=ρ.g.H + Po,式中：P表示液位傳感器測(cè)量點(diǎn)直接接觸液面所受壓力， ρ表示被測(cè)液體的密度值，g表示重力加速度,Po是液面上大氣壓,H是傳感器投入液體的深度同時(shí)，通過(guò)導(dǎo)氣不銹鋼將液體的壓力引入到傳感器的正壓腔，再將液面上的大氣壓Po與傳感器的負(fù)壓腔相連，以抵消傳感器背面的Po，使傳感器測(cè)得壓力為：ρ.g.H，顯然,通過(guò)測(cè)取壓力P，可以得到液位深。 </p> <p> 2、液位測(cè)量法：液位測(cè)量方法可分為機(jī)械高度法和壓強(qiáng)測(cè)定法。機(jī)械高度：機(jī)械傳動(dòng)結(jié)構(gòu)復(fù)雜，器械的豎直度影響測(cè)量精度。并且是筆繪模擬曲線或人工讀數(shù)。壓強(qiáng)法：利用埋于液體底部或一定深度的壓力傳感器測(cè)定壓力，利用公式Pa=ρCH得到液位的高度。又可根據(jù)容器的結(jié)構(gòu)設(shè)計(jì)尺寸得到相應(yīng)高度的容器容量——所盛液體的體積。壓力傳感器輸出的是與壓力傳感器成正比的電信號(hào)，可以遠(yuǎn)距離傳輸，并便于自動(dòng)記錄和為處理器的修正、補(bǔ)償，進(jìn)一步提高精度。 </p> <p> <br /> 從精度角度來(lái)分類，因?yàn)槲覈?guó)國(guó)標(biāo)的精度就為0.5%.　所以近年來(lái)又可以分為高精度壓力變送器和一般壓力變送器。水暖管道壓力變送器聯(lián)系方式</p><p
