    產(chǎn)品描述

    一體化RTD熱電阻，衛(wèi)生型結(jié)構(gòu)設(shè)計(jì)

    具有多種過程連接形式和延長頸類型

     

    • 高靈活性：模塊化結(jié)構(gòu)設(shè)計(jì)、標(biāo)準(zhǔn)接線端子塊和用戶自定義熱電阻插入深度
    • 提供絕大多數(shù)常見的EHEDG認(rèn)證衛(wèi)生型過程連接，儀表的結(jié)構(gòu)設(shè)計(jì)符合3A衛(wèi)生型標(biāo)準(zhǔn)
    • 高精度測量：采用符合IEC 60751 (A級或更高等級)的Pt100溫度傳感器

    • 可滿足防爆區(qū)中的測量要求：
      - 本安型儀表(Ex ia)
      - 無火花 (Ex nA)

     

    一體化溫度變送器

    相比于不經(jīng)過溫度變送器，而直接接線的測量方式，Endress+Hauser的一體式溫度變送器具有更高的測量精度和更高的測量可靠性。根據(jù)實(shí)際應(yīng)用工況，用戶可以自由選擇下列信號輸出模式和通信方式：

     

    • 4...20 mA模擬輸出
    • HART®
    • PROFIBUS® PA
    • FF基金會現(xiàn)場總線

     

    應(yīng)用領(lǐng)域

    • 可用于食品、制藥等衛(wèi)生領(lǐng)域和精細(xì)化工行業(yè)的測量

    • 溫度測量范圍: -50...250 °C

    • 承壓能力可達(dá) 40 bar

    • 防護(hù)等級可達(dá) IP 68
