style="text-indent:25px">數(shù)顯壓力開關(guān)是如何安裝的？數(shù)顯壓力開關(guān)系統(tǒng)的正確安裝包括取壓口的開口位置、連接導(dǎo)管的合理鋪設(shè)和儀表安裝位置的正確：1．取壓口的位置選擇：（1）避免處于管路彎曲、分叉及流束形成渦流的區(qū)域。（2）當(dāng)管路中有突出物體（如測溫組件）時，取壓口應(yīng)取在其前面。（3）當(dāng)必須在調(diào)節(jié)閥門附近取壓時，若取壓口在其前，則與閥門距離應(yīng)不小于2倍管徑；若取壓口在其后，則與閥門距離應(yīng)不小于3倍管徑。（4）對于寬廣容器，取壓口應(yīng)處于流體流動平穩(wěn)和無渦流的區(qū)域?？傊?，在工藝流程上確定的取壓口位置應(yīng)能保證測得所要選取的工藝參數(shù)。2．連接導(dǎo)管的鋪設(shè)，連接導(dǎo)管的水平段應(yīng)有一定的斜度，以利于排除冷凝液體或氣體。當(dāng)被測介質(zhì)為氣體時，導(dǎo)管應(yīng)向取壓口方向低傾；當(dāng)被測介質(zhì)為液體時，導(dǎo)管則應(yīng)向測壓儀表方向傾斜；當(dāng)被測參數(shù)為較小的差壓值時，傾斜度可再稍大一點(diǎn)。此外，如導(dǎo)管在上下拐彎處，數(shù)顯液位傳感器供應(yīng)商，數(shù)顯液位傳感器供應(yīng)商，則應(yīng)根據(jù)導(dǎo)管中的介質(zhì)情況，數(shù)顯液位傳感器供應(yīng)商，在較低點(diǎn)安置排泄冷凝液體裝置或在較高處安置排氣裝置，以保證在相當(dāng)長的時間內(nèi)不致因在導(dǎo)管中積存冷凝液體或氣體而影響測量的準(zhǔn)確度。數(shù)顯壓力傳感器有較高的精度和分辨率。數(shù)顯液位傳感器供應(yīng)商</p><div
