靜電(dian)高(gao)壓(ya)表(biao)是(shi)基於(yu)靜(jing)電(dian)作用(yong)力(li)。在(zai)兩(liang)個(ge)特定的電(dian)極(ji)間(jian)加(jia)電(dian)壓(ya)，電(dian)極(ji)間(jian)就(jiu)會受(shou)到(dao)靜(jing)電(dian)力(li)f的作用(yong)，f的大(da)小(xiao)和電(dian)壓(ya)u的數值有(you)固(gu)定(ding)關(guan)系(xi)。通過(guo)測(ce)量f的大(da)小(xiao)或(huo)它引(yin)起的可動極(ji)板(ban)的位(wei)移或(huo)偏轉，就(jiu)能確定所加(jia)電(dian)壓(ya)u的大(da)小(xiao)。

SGB系列交直(zhi)流(liu)數字高(gao)壓(ya)表(biao)有精密高(gao)壓(ya)薄膜(mo)電(dian)容(rong)和精(jing)密(mi)高(gao)壓(ya)玻璃(li)釉(you)電(dian)阻全金(jin)屬封(feng)閉結構(gou)屏(ping)蔽美(mei)國杜(du)邦(bang)填(tian)充(chong)材(cai)料(liao)，特種工藝灌(guan)封(feng)，同(tong)軸(zhou)電(dian)纜(lan)連(lian)接(jie)，鋁合(he)金(jin)包(bao)裝箱(xiang)
