外接標(biāo)準(zhǔn)鉑電阻—JOFRA STS-200A 925 配套產(chǎn)品: 液槽、干體爐 兩用標(biāo)準(zhǔn)爐 RTC-250B 液槽、干體爐 兩用標(biāo)準(zhǔn)爐 RTC-250C 智能參考探頭 JOFRA STS-200智能參考探頭內(nèi)置了溫度特性曲線及相應(yīng)參數(shù)。同樣,DLC探頭也是如此。 這就意味著,無需通過電腦下載溫度補(bǔ)償參數(shù)這一繁瑣耗時并且容易出錯的工作,既然參數(shù)已經(jīng)儲存在智能接頭中,而且出廠前已經(jīng)消除了更換不同探頭引起的誤差,當(dāng)然用戶可以隨意更換使用,且即插即用。 的參考探頭 STS-200 參考探頭和DLC探頭是特殊設(shè)計的。AMETEK可以提供形狀為90°彎角的參考探頭和DLC探頭,這些探頭在插入套管時,上端僅比套管頂部稍高。 這種特殊設(shè)計可以非常方便地校準(zhǔn)那些頂部帶有接線盒或法蘭的溫度傳感器STS-200 外接參考探頭一旦超出校準(zhǔn)周期會有提示。 真值穩(wěn)定(僅B型和C型) 只有RTC系列干體爐的 B 型和C 型有此功能,此功能可以使用外部參考探頭控溫達(dá)到設(shè)定點溫度。當(dāng)嚴(yán)格要求加熱體中的溫度等于設(shè)定點溫度時就可以使用外部參考探頭來控溫。這項功能在校準(zhǔn)氣體修正器或其他保管變換時非常理想。 技術(shù)技術(shù)指標(biāo) STS-200A 925 溫度范圍 STS-200............................................0~250°C 準(zhǔn)確度 F.S.
