熱電阻是利用物質(zhì)在溫度變化時(shí)本身電阻也隨著發(fā)生變化的特性來(lái)測(cè)量溫度的。熱電阻的受熱部分(感溫元件)是用細(xì)金屬絲均勻地雙繞在絕緣材料制成的骨架上,當(dāng)被測(cè)介質(zhì)中有溫度梯度存在時(shí),所測(cè)得的溫度是感溫元件所在范圍內(nèi)介質(zhì)層中的平均溫度. | 特 點(diǎn) | 全國(guó)統(tǒng)一設(shè)計(jì)產(chǎn)品,接口尺寸通用,互換性好; | 采用裝配式結(jié)構(gòu),零件分解性好,維修方便; | 更換易損件成本低; | 規(guī)格齊全,性能穩(wěn)定可靠。 | 絕緣電阻 | 裝配鉑熱電阻的常溫絕緣電阻應(yīng)不小于100MΩ | 裝配銅熱電阻的常溫絕緣電阻應(yīng)不小于50MΩ | 常溫絕緣電阻的試驗(yàn)電壓為10~100V DC。 | 自熱影響:鉑電阻允許通過(guò)的zui大電流為5mA,由此產(chǎn)生的溫升不大于0.3℃。 | 熱響應(yīng)時(shí)間:在溫度出現(xiàn)階躍變化時(shí),熱電阻的輸出變化至相當(dāng)于該階躍變化的50%,所需要的時(shí)間,稱為熱響應(yīng)時(shí)間,用τ0.5表示。 |

熱電阻zui小插入深度:應(yīng)不小于其保護(hù)套管外徑的8-10倍。 | 絕緣電阻:當(dāng)周圍空氣溫度為15-35℃,相對(duì)濕度<80%時(shí),絕緣電阻 20兆歐(電壓100V) | 。具有防濺式接線盒的絕緣電阻應(yīng)2兆歐(電壓100V) | 熱電阻感溫元件在0℃ 時(shí)電阻值(R0)及其與在100℃ 時(shí)的電阻值(R100)比值: |
