實(shí)際上廠家對(duì)智能變送器的校準(zhǔn)也是有說(shuō)明的，如ABB的變送器，對(duì)校準(zhǔn)就有:“設(shè)定量程”、“重定量程”、“微調(diào)”之分。其中“設(shè)定量程”操作主要是通過(guò)LRV.URV的數(shù)字設(shè)定來(lái)完成配置工作，而“重定量程”操作則要求將變送器連接到標(biāo)準(zhǔn)壓力源上，通過(guò)一系列指令引導(dǎo)，由變送器直接感應(yīng)實(shí)際壓力并對(duì)數(shù)值進(jìn)行設(shè)置。而量程的初始、終設(shè)置直接取決于真實(shí)的壓力輸入值。但要看到盡管變送器的模擬輸出與所用的輸入值關(guān)系正確，但過(guò)程值的數(shù)字讀數(shù)顯示的數(shù)值會(huì)略有不同，這可通過(guò)微調(diào)項(xiàng)來(lái)進(jìn)行校準(zhǔn)。由于各部分既要單獨(dú)調(diào)校又必需要聯(lián)調(diào)，LED顯示壓力變送器價(jià)格查詢，因此實(shí)際校準(zhǔn)時(shí)可按以下步驟進(jìn)行： </p> <p> 1．先做一次4-20mA微調(diào)，用以校正變送器內(nèi)部的D/A轉(zhuǎn)換器，由于其不涉及傳感部件，無(wú)需外部壓力信號(hào)源。 </p> <p> 2．再做一次全程微調(diào)，使4-20mA、數(shù)字讀數(shù)與實(shí)際施加的壓力信號(hào)相吻合，因此需要壓力信號(hào)源。 </p> <p> 3．做重定量程，通過(guò)調(diào)整使模擬輸出4-20mA與外加的壓力信號(hào)源相吻合，其作用與變送器外殼上的調(diào)零(Z)、調(diào)量程(R)開(kāi)關(guān)的作用完全相同，LED顯示壓力變送器價(jià)格查詢。 </p> <p> 壓力變送器是一種比較常用的測(cè)量?jī)x器，可以將測(cè)壓元件受到的氣體、液體等物理參數(shù)轉(zhuǎn)變成標(biāo)準(zhǔn)的信號(hào)輸出，具有測(cè)量精細(xì)、性能穩(wěn)定、靈敏度高，LED顯示壓力變送器價(jià)格查詢、操作簡(jiǎn)便等優(yōu)點(diǎn)。能與各種型號(hào)的動(dòng)圈式指示儀、數(shù)字壓力表、電子電位差計(jì)配套使用，也能與智能調(diào)節(jié)儀或計(jì)算機(jī)系統(tǒng)配套使用。LED顯示壓力變送器價(jià)格查詢</p><div

壓力變送器經(jīng)過(guò)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(lái)越多。這符合整個(gè)變送器行業(yè)發(fā)展細(xì)分化的需求。不同類(lèi)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(lèi)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(guò)程中注意不要讓介質(zhì)溫度超過(guò)壓力變送器的工作溫度。必要時(shí)，需加裝冷卻裝置（冷凝管、盤(pán)管）。 </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(wú)近壓孔、無(wú)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(wàn)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(wú)法使用。寧夏防爆壓力變送器哪個(gè)好壓力變送器主要使用的壓電材料有石英、磷酸二氫胺和酒石酸鉀鈉。石英，它是種天然晶體。</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
