style="text-indent:25px">熱敏電阻溫度傳感器：熱敏電阻是用半導(dǎo)體材料，大多為負(fù)溫度系數(shù)，即阻值隨溫度增加而降低。溫度變化會造成大的阻值改變，因此它是**靈敏的溫度傳感器。但熱敏電阻的線性度極差，并且與生產(chǎn)工藝有很大關(guān)系。制造商給不出標(biāo)準(zhǔn)化的熱敏電阻曲線。熱敏電阻體積非常小，對溫度變化的響應(yīng)也快。但熱敏電阻需要使用電流源，小尺寸也使它對自熱誤差極為敏感。熱敏電阻在兩條線上測量的是***溫度，有較好的精度，但它比熱偶貴，可測溫度范圍也小于熱偶。一種常用熱敏電阻在25℃時的阻值為5kΩ，每1℃的溫度改變造成200Ω的電阻變化。注意10Ω的引線電阻*造成可忽略的 0.05℃誤差。它非常適合需要進(jìn)行快速和靈敏溫度測量的電流控制應(yīng)用。尺寸小對于有空間要求的應(yīng)用是有利的，但必須注意防止自熱誤差。熱敏電阻還有其自身的測量技巧。熱敏電阻體積小是優(yōu)點(diǎn)，它能很快穩(wěn)定，不會造成熱負(fù)載。不過也因此很不結(jié)實(shí)，大電流會造成自熱。由于熱敏電阻是一種電阻性器件，任何電流源都會在其上因功率而造成發(fā)熱。功率等于電流平方與電阻的積。因此要使用小的電流源。如果熱敏電阻暴露在高熱中，將導(dǎo)致長久性的損壞。通過對兩種溫度儀表的介紹，希望對大家工作學(xué)習(xí)有所幫助。節(jié)溫器缺點(diǎn)是節(jié)溫器在工作時經(jīng)常開閉，產(chǎn)生振蕩現(xiàn)象。廣西河柴HND柴油機(jī)閥芯經(jīng)驗(yàn)豐富</p><p
