1)儀表類型的選擇
壓力檢測(cè)儀表的選用是一項(xiàng)重要工作.類型的選擇必須從生產(chǎn)工藝要求、被測(cè)介質(zhì)的性質(zhì)、使用環(huán)境條件等方面綜合考慮,要考慮生產(chǎn)工藝是否要求壓力信號(hào)現(xiàn)場(chǎng)指示、遠(yuǎn)傳、報(bào)警、自動(dòng)記錄;被測(cè)介質(zhì)有無(wú)腐蝕性、溫度大小、溫度與壓力高低、易燃易爆情況、是否易結(jié)品等;現(xiàn)場(chǎng)環(huán)境條件如振動(dòng)、電磁場(chǎng)、腐蝕性、高低溫等問(wèn)題.正確選用儀表類型是保證儀表正常工作及生產(chǎn)安全進(jìn)行的主要前提,如果選用不當(dāng),不僅不能正確、及時(shí)地反映被測(cè)對(duì)象壓力的變化,還可能引起事故.所以選用時(shí)應(yīng)根據(jù)具體情況,全面考慮,并本著節(jié)約的原則合理地考慮儀表的覽程、精度、類型等。選用時(shí)主要應(yīng)考慮以下幾個(gè)方面。
