ZX系列十進(jìn)位電阻箱
ZX系列十進(jìn)位電阻箱
ZX74系列十進(jìn)位電阻箱具有極高的精度和穩(wěn)定的六撥號(hào)儀表。該系列共有4個(gè)版本,最大電阻為1,111,111Ω。ZX83系列增加了另外兩個(gè)Decade Box,將電阻范圍擴(kuò)展到111,111,100Ω。
使用特別選擇的合金的電阻絲將電阻元件無(wú)感地纏繞在高質(zhì)量的成形器上。每個(gè)電阻元件都經(jīng)過(guò)熱處理并經(jīng)過(guò)可控的老化過(guò)程,以產(chǎn)生最高的穩(wěn)定性和低溫度系數(shù)。
開(kāi)關(guān)具有最高質(zhì)量和低壓觸點(diǎn),使用壽命長(zhǎng),可靠性高。每十年開(kāi)關(guān)采用全封閉結(jié)構(gòu)制造,無(wú)需維護(hù)。這十個(gè)箱子裝在堅(jiān)固耐用的金屬外殼內(nèi),帶有可伸縮的提手。
非常受歡迎的ZX74型號(hào)具有最低十倍,步長(zhǎng)為1mΩ。這對(duì)電阻溫度計(jì)仿真和電阻橋網(wǎng)絡(luò)特別有用。所有型號(hào)都有一個(gè)額外的端子連接到靜電屏幕,AC可能需要。橋梁應(yīng)用。
ZX90系列十進(jìn)位電阻箱由10個(gè)儀器組成,可覆蓋高達(dá)1,111,111Ω的電阻范圍,儀器可在4,5,6和7年內(nèi)使用。雖然它們成本低,但這些儀器具有高質(zhì)量并且具有精確的低接觸電阻開(kāi)關(guān)。
電阻元件由漆包錳酸鹽線制成,其無(wú)感應(yīng)地纏繞在高質(zhì)量的成形器上。每個(gè)電阻元件都經(jīng)過(guò)熱處理,并經(jīng)過(guò)可控的老化過(guò)程,以產(chǎn)生最高的穩(wěn)定性并實(shí)現(xiàn)低溫度系數(shù)。這些儀器安裝在一個(gè)吸引人的金屬外殼中,既堅(jiān)固又防塵。
