BA328C是本質安全的4¹/₂數(shu)字面板(ban)(ban)安(an)裝指示(shi)(shi)器(qi)，該儀器(qi)回(hui)路(lu)供(gong)電(dian)(dian)(dian)。BA328C的主要應用是(shi)顯(xian)(xian)示(shi)(shi)在(zai)一(yi)個危(wei)險的過程區域測量(liang)(liang)變量(liang)(liang)或(huo)控制(zhi)信(xin)(xin)號。顯(xian)(xian)示(shi)(shi)器(qi)的零位和跨距(ju)是(shi)獨立可(ke)(ke)調的，以(yi)使指示(shi)(shi)器(qi)可(ke)(ke)以(yi)很(hen)容(rong)(rong)易(yi)(yi)(yi)地進行現(xian)場校準(zhun)，因此通過一(yi)個4 /20mA的電(dian)(dian)(dian)流顯(xian)(xian)示(shi)(shi)任何線(xian)性(xing)或(huo)平方(fang)律信(xin)(xin)號，例如溫(wen)度、流量(liang)(liang)或(huo)壓力。一(yi)個可(ke)(ke)選(xuan)的16點線(xian)性(xing)化能(neng)使BA328C在(zai)線(xian)性(xing)工程單(dan)元顯(xian)(xian)示(shi)(shi)非(fei)(fei)線(xian)性(xing)的變量(liang)(liang)，以(yi)及兩個可(ke)(ke)選(xuan)的報(bao)警(jing)能(neng)夠(gou)控制(zhi)危(wei)險或(huo)安(an)全(quan)區域負荷。并且，國際內部安(an)全(quan)認(ren)證使BA328C可(ke)(ke)以(yi)安(an)裝在(zai)世(shi)界任何地方(fang)4/20mA端子(zi)符合(he)簡單(dan)的設備的要求(qiu)，它(ta)(ta)能(neng)夠(gou)與大(da)多數(shu)認(ren)證的本質安(an)全(quan)電(dian)(dian)(dian)路(lu)連接，其中(zhong)與低電(dian)(dian)(dian)壓降連接，使儀器(qi)很(hen)容(rong)(rong)易(yi)(yi)(yi)被使用。前(qian)面板(ban)(ban)同(tong)樣是(shi)非(fei)(fei)常強大(da)的，它(ta)(ta)容(rong)(rong)易(yi)(yi)(yi)清潔(jie)，儀器(qi)的成型使用非(fei)(fei)反射，防刮聚酯(zhi)膜(mo)密封。
