產(chǎn)品詳情

補償導(dǎo)線(補償電纜)是指在一定溫度范圍內(nèi),具有與其所匹配熱電偶的熱電動勢相同標(biāo)稱值的一對且?guī)в薪^緣層的導(dǎo)線,用它們連接熱電偶與溫度顯示控制儀表,以補償它們與熱電偶連接處的溫度變化所產(chǎn)生的誤差。
補償導(dǎo)線(補償電纜)適用于電力、冶金、石油、化工、輕紡等工業(yè)以及國防、科研等部門自動化測溫儀表的單點或多點連接。
產(chǎn)品標(biāo)準(zhǔn):
補償導(dǎo)線: GB/T4989-94
使用特性:
使用溫度:耐熱級: -65 ℃ ~+200 ℃及 -65 ℃ ~+260 ℃兩種;
普通級: -40 ℃ ~+70 ℃及 -40 ℃ ~+105 ℃兩種;
zui小彎曲半徑:補償導(dǎo)線:不小于導(dǎo)體外徑 8 倍;
補償電纜:有鎧裝時不小于電纜外徑 12 倍,無鎧裝時不小于電纜外徑 6 倍
