混凝土測溫儀適用于各類建筑工程的現場施工測溫,與測溫探頭配合可測材料和熟料溫度,如:氣體、液體、流體、拌合物和顆粒狀材料;與預埋式測溫線配合可測冬期施工混凝土和混凝土內部溫度。 混凝土測溫儀使(shi)用(yong)方(fang)法:
1.混凝(ning)土測溫(wen)儀(yi)用主機與(yu)測溫(wen)探頭測量(liang)材(cai)料(liao)溫(wen)度(du)
將(jiang)測(ce)(ce)溫(wen)(wen)探頭(tou)(tou)的(de)插(cha)頭(tou)(tou)插(cha)入(ru)(ru)(ru)主機插(cha)座,按下電源開(kai)關(guan),將(jiang)測(ce)(ce)溫(wen)(wen)探頭(tou)(tou)金(jin)屬桿(gan)插(cha)入(ru)(ru)(ru)被測(ce)(ce)物中(zhong),插(cha)入(ru)(ru)(ru)深度(du)不少于其長度(du)的(de)1/2,兩分(fen)鐘左(zuo)右在(zai)主機上讀取溫(wen)(wen)度(du)數據(ju)。在(zai)測(ce)(ce)量拌(ban)合(he)物溫(wen)(wen)度(du)時,為避(bi)免測(ce)(ce)溫(wen)(wen)探頭(tou)(tou)與拌(ban)合(he)物中(zhong)的(de)硬物過度(du)撞擊而影響使用壽命(ming),可(ke)先用金(jin)屬棍在(zai)拌(ban)合(he)物中(zhong)預留孔(kong),再將(jiang)測(ce)(ce)溫(wen)(wen)探頭(tou)(tou)插(cha)入(ru)(ru)(ru)孔(kong)中(zhong)測(ce)(ce)溫(wen)(wen)。每次用后(hou)應將(jiang)測(ce)(ce)溫(wen)(wen)探頭(tou)(tou)擦拭干(gan)凈。
2.混凝(ning)土(tu)測溫(wen)(wen)儀用主(zhu)機與測溫(wen)(wen)線(xian)測量(liang)混凝(ning)土(tu)溫(wen)(wen)度
施工(gong)測(ce)(ce)溫(wen)(wen)方案確(que)定后,根(gen)據測(ce)(ce)溫(wen)(wen)點(dian)(dian)(dian)數(shu)量和深(shen)(shen)度(du)(du)(du)選(xuan)用(yong)長度(du)(du)(du)規格(ge)合適的(de)(de)測(ce)(ce)溫(wen)(wen)線,例如:實(shi)際測(ce)(ce)溫(wen)(wen)點(dian)(dian)(dian)深(shen)(shen)0.2m~0.3m,可選(xuan)用(yong)規格(ge)為(wei)0.5m的(de)(de)測(ce)(ce)溫(wen)(wen)線;實(shi)際測(ce)(ce)溫(wen)(wen)點(dian)(dian)(dian)深(shen)(shen)2.5m~2.8m,可選(xuan)用(yong)規格(ge)為(wei)3m的(de)(de)測(ce)(ce)溫(wen)(wen)線,以次類(lei)推。預(yu)埋時可用(yong)鋼筋(jin)等桿件(jian)作(zuo)支(zhi)承(cheng)物(wu),將(jiang)測(ce)(ce)溫(wen)(wen)線按(an)(an)照縱向測(ce)(ce)溫(wen)(wen)點(dian)(dian)(dian)距離綁在(zai)支(zhi)承(cheng)物(wu)上,溫(wen)(wen)度(du)(du)(du)傳(chuan)(chuan)感器與支(zhi)承(cheng)物(wu)之間應(ying)做隔熱處理。在(zai)澆筑混凝(ning)土(tu)時,將(jiang)綁好測(ce)(ce)溫(wen)(wen)線的(de)(de)支(zhi)承(cheng)物(wu)植入混凝(ning)土(tu)中,溫(wen)(wen)度(du)(du)(du)傳(chuan)(chuan)感器處于測(ce)(ce)溫(wen)(wen)點(dian)(dian)(dian)位(wei)置,插頭(tou)留在(zai)混凝(ning)土(tu)外面并(bing)用(yong)塑料袋罩好,避免潮濕,保持清潔。為(wei)便于操作(zuo),留在(zai)外面的(de)(de)導(dao)線長度(du)(du)(du)應(ying)大于20cm。測(ce)(ce)溫(wen)(wen)時,按(an)(an)下主(zhu)機(ji)電源(yuan)開關,將(jiang)測(ce)(ce)溫(wen)(wen)線插頭(tou)插入主(zhu)機(ji)插座中,主(zhu)機(ji)顯(xian)示屏上即可顯(xian)示相(xiang)應(ying)測(ce)(ce)溫(wen)(wen)點(dian)(dian)(dian)的(de)(de)溫(wen)(wen)度(du)(du)(du)。
3.混(hun)凝土(tu)測(ce)溫儀用主機與測(ce)溫線測(ce)量冬期施(shi)工(gong)混(hun)凝土(tu)溫度(du)
在澆(jiao)筑(zhu)混凝土時,按冬(dong)期施工測(ce)(ce)溫(wen)(wen)方(fang)案預(yu)留測(ce)(ce)溫(wen)(wen)孔(kong),在每個孔(kong)內放置一(yi)支(zhi)測(ce)(ce)溫(wen)(wen)線,測(ce)(ce)溫(wen)(wen)線的插頭留在孔(kong)外(wai)并用(yong)塑(su)料袋罩好(hao),避(bi)免潮濕,保持清(qing)潔。測(ce)(ce)溫(wen)(wen)時,按下主(zhu)機電(dian)源開關,將(jiang)測(ce)(ce)溫(wen)(wen)線插頭插入(ru)(ru)主(zhu)機插座中,主(zhu)機顯示屏上即可(ke)顯示相應測(ce)(ce)溫(wen)(wen)點(dian)的溫(wen)(wen)度(du)。每階(jie)段測(ce)(ce)溫(wen)(wen)結束后(hou)將(jiang)測(ce)(ce)溫(wen)(wen)線收存好(hao),以備(bei)下次再用(yong)。也可(ke)將(jiang)測(ce)(ce)溫(wen)(wen)線埋入(ru)(ru)混凝土中一(yi)次性(xing)使(shi)用(yong),具體作法見使(shi)用(yong)方(fang)法“2”。
4.混(hun)凝土(tu)測溫(wen)儀夜間測溫(wen)讀數照明(ming)功(gong)能的使用
在夜間或黑暗環境下(xia)使(shi)用時,按下(xia)主機照明(ming)開關(guan),液(ye)晶顯示屏可發出淡綠色的背景光,使(shi)讀數清晰(xi)醒目。
