防爆感應式電接點壓力表

防爆感應式電接點壓力表是于(yu)某些有(you)(you)爆炸危 險場所的儀表(biao)(biao)，該表(biao)(biao)具有(you)(you)對工(gong)藝流程中的流體介質 的壓力參量進行檢測(ce)、自動(dong)控制(zhi)、自動(dong)報警等功能。 主要用(yong)于(yu)核電、化工(gong)、船舶、冶金(jin)等行業(ye)。

防爆感應式電接點壓力表按《GB3836.1—2000爆(bao)炸性環(huan)境用防爆(bao)電氣 設(she)備通用要求》和《GB3836.4—~2000爆(bao)炸性環(huan)境電 氣設(she)備本質安全(quan)(quan)型電路和電氣設(she)備“i”》兩標準設(she) 計制(zhi)造的(de)，并經*儀器儀表防爆(bao)站(zhan)安全(quan)(quan)監(jian)督檢(jian) 驗(yan)站(zhan)檢(jian)驗(yan)儀表與安全(quan)(quan)柵（推薦選用德國“P+F”公司的(de) KFD2-SR2-EX1.w或(huo)KFD2-SR2—Ex2-w）配套(tao) 使用，可構成本質安全(quan)(quan)防爆(bao)系統。儀表防爆(bao)標志為 ExibllCT6；儀表防爆(bao)合(he)格證編號為GYB05169。該表 可適(shi)用于戶(hu)內或(huo)有遮蓋物的(de)1區和2區的(de)爆(bao)炸性工(gong) 廠危(wei)險場(chang)所。

的測量系統由彈簧管、拉桿和齒輪傳動機構、示值部件組成。被測介質的壓力作用于彈簧管，使其自由端產位移，由拉桿傳至齒輪傳動機構予以放大，并轉換成指針的轉動，在度盤上指示出被測壓力值。
