鉑電阻和銅電阻的應用范圍分析

鉑電阻和銅電阻的應用范圍分析:
    為什么在鉑絲價(jià)格高于銅的前提下,反而工業(yè)上現場(chǎng)用的都是鉑電阻而不是銅電阻?
    1.鉑電阻的測溫范圍比銅電阻測量范圍寬。銅電阻測溫范圍:-50~150攝氏度鉑電阻測溫范圍:-200~850攝氏度
    2.鉑電阻精度高、性能可靠、抗氧化性好、物理化學(xué)性能穩定,與其他熱電阻相比,有較高的電阻率,初一般測溫元件外,還可作為標準器件。缺點(diǎn)是:電阻與溫度呈非線(xiàn)性關(guān)系、價(jià)格較貴,高溫下不宜在還原性介質(zhì)中使用。
    3.銅電阻電阻率低,易氧化,在溫度不高時(shí)可以選用。優(yōu)點(diǎn):價(jià)錢(qián)便宜,電阻值與溫度基本為線(xiàn)性關(guān)系。
