進(jìn)入冬季要提前做好儀器儀表的保溫防凍措施,隨著溫度逐漸降低,當(dāng)被測介質(zhì)通過測量管線傳送到變送器時,常出現(xiàn)環(huán)境溫度過低時就會發(fā)生凍結(jié)、凝固、析出結(jié)晶等現(xiàn)象,因環(huán)境溫度過低而超出所使用儀表的正常工作溫度區(qū)間,RTN C3/15t稱重傳感器直接影響到儀表測量顯示的準(zhǔn)確性。而壓力、流量、液位、溫度等各類儀表點(diǎn),其測量介質(zhì)多為液體,受低溫的影響,更容易造成測量誤差,嚴(yán)重者可能引發(fā)中毒、火災(zāi)、等安全事故。

儀器儀表的防寒防凍工作就顯得特別重要。一些大型儀器儀表用戶更是早早的做好了應(yīng)對措施,比如電廠、水廠、石油、化工業(yè)等都制定了適合自己企業(yè)的防寒防凍工作制度。下面讓我們來探討一下冬季儀表用戶應(yīng)該如何進(jìn)行儀表防凍工作。
對儀表和儀表測量管線進(jìn)行防凍處理,需要伴熱保溫的對象主要有安裝在儀表保溫箱內(nèi)的變送器,外浮筒式液位變送器或其它形式的露天安裝的液位變送單元,壓力,差壓,流量等儀表的檢測管線和測量管線。通過選型或其他方式避免此類事故發(fā)生。采取的措施通常有:選型,保溫伴熱,維護(hù)等。
