style="font-size:18px;">需要根據(jù)《JJG882-2004壓力變送器檢定規(guī)程》開(kāi)展校準(zhǔn)工作，需要的設(shè)備如下：</span> </p> <p> <span style="font-size:18px;"> 1、DC 24V供電電源一臺(tái)；</span> </p> <p> <span style="font-size:18px;"> 2、mA電流表一臺(tái)；</span> </p> <p> <span style="font-size:18px;"> 3、電壓表一臺(tái)；</span> </p> <p> <span style="font-size:18px;"> 4、標(biāo)準(zhǔn)壓力表一臺(tái)；</span> </p> <p> <span style="font-size:18px;"> 5、壓力源一臺(tái)；</span> </p> <p> <span style="font-size:18px;"> 6、活塞式壓力計(jì)一臺(tái)（有此項(xiàng)時(shí)，4、5為選配）。</span> </p> <p> <br /> </p> <p> <span style="font-size:18px;"> 目前數(shù)字壓力校驗(yàn)儀集成了DC24V、電壓測(cè)量、電流測(cè)量、通斷測(cè)量等多種功能，設(shè)備向智能化、小型化不斷發(fā)展，例如您只需要配置ConST273智能數(shù)字壓力校驗(yàn)儀和ConST100系列壓力泵，即可完成為HART智能壓力變送器、普通壓力變送器、精密壓力表、一般壓力表、壓力控制器等壓力儀表的檢定工作。</span> </p><p> <span style="font-size:18px;">變送器故障分析和處理主要方法</span> </p> <p> <span style="font-size:18px;color:#E53333;"><strong>A替換法</strong></span> </p> <p> <span style="font-size:18px;">準(zhǔn)備一塊正常使用的變送器直接替換懷疑有故障的。</span><span style="font-size:18px;">這樣可以簡(jiǎn)單快捷的判定是變送器本身的故障還是管路或其他設(shè)備的故障。</span> </p> <p> <span style="font-size:18px;color:#E53333;"><strong>B斷路法</strong></span> </p> <p> <span style="font-size:18px;">將懷疑有故障的部分與其它部分分開(kāi)來(lái)，查看故障是否消失，如果消失，則確定故障所在，否則可進(jìn)行下一步查找，如：智能差壓變送器不能正常Hart遠(yuǎn)程通訊，可將電源從儀表本體上斷開(kāi)，用現(xiàn)場(chǎng)另加電源的方法為變送器通電進(jìn)行通訊，以查看是否電纜是否疊加約2kHz的電磁信號(hào)而干擾通訊。</span> </p> <p> <span style="font-size:18px;color:#E53333;"><strong>C.短路檢測(cè)</strong></span> </p> <p> <span style="font-size:18px;">在保證安全的情況下，將相關(guān)部分回路直接短接，如：差變送器輸出值偏小，可將導(dǎo)壓管斷開(kāi)，從一次取壓閥外直接將差壓信號(hào)直接引到差壓變送器雙側(cè)，觀察變送器輸出，以判斷導(dǎo)壓管路的堵、漏的連通性。</span> 壓力控制器的精確度。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="廈門差壓壓力控制器生產(chǎn)廠家,壓力控制器"

使用在煉化裝置中的智能壓力變送器，其輸出信號(hào)的經(jīng)電纜連接在DCS系統(tǒng)上，操作人員通過(guò)DCS系統(tǒng)操作站來(lái)監(jiān)控裝置現(xiàn)場(chǎng)壓力。在出現(xiàn)智能壓力變送器故障時(shí)，DCS操作站上會(huì)顯示測(cè)量值偏高、偏低，或出現(xiàn)測(cè)量回路IOP（- ）報(bào)警。在處理故障時(shí)，首先要判斷是現(xiàn)場(chǎng)儀表的故障，還是DCS系統(tǒng)的故障。如果是現(xiàn)場(chǎng)儀表故障，那么就需要針對(duì)儀表故障的實(shí)際情況進(jìn)行多角度的分析，并且根據(jù)所使用儀表的特點(diǎn)，采取相應(yīng)的處理措施進(jìn)行處理；如果故障檢測(cè)結(jié)果顯示是DCS系統(tǒng)的故障，就需要系統(tǒng)維護(hù)人員配合處理。</span>
