ZX系列十進位電阻箱
ZX系列十進位電阻箱
ZX74系列十進位電阻箱具有極高的精度和穩定的六撥號儀表。該系列共有4個版本,最大電阻為1,111,111Ω。ZX83系列增加了另外兩個Decade Box,將電阻范圍擴展到111,111,100Ω。
使用特別選擇的合金的電阻絲將電阻元件無感地纏繞在高質量的成形器上。每個電阻元件都經過熱處理并經過可控的老化過程,以產生最高的穩定性和低溫度系數。
開關具有最高質量和低壓觸點,使用壽命長,可靠性高。每十年開關采用全封閉結構制造,無需維護。這十個箱子裝在堅固耐用的金屬外殼內,帶有可伸縮的提手。
非常受歡迎的ZX74型號具有最低十倍,步長為1mΩ。這對電阻溫度計仿真和電阻橋網絡特別有用。所有型號都有一個額外的端子連接到靜電屏幕,AC可能需要。橋梁應用。
ZX90系列十進位電阻箱由10個儀器組成,可覆蓋高達1,111,111Ω的電阻范圍,儀器可在4,5,6和7年內使用。雖然它們成本低,但這些儀器具有高質量并且具有精確的低接觸電阻開關。
電阻元件由漆包錳酸鹽線制成,其無感應地纏繞在高質量的成形器上。每個電阻元件都經過熱處理,并經過可控的老化過程,以產生最高的穩定性并實現低溫度系數。這些儀器安裝在一個吸引人的金屬外殼中,既堅固又防塵。
