一體化RTD熱電阻，衛生型結構設計

具有多種過程連接形式和延長頸類型

• 高靈活性：模塊化結構設計、標準接線端子塊和用戶自定義熱電阻插入深度
• 提供絕大多數常見的EHEDG認證衛生型過程連接，儀表的結構設計符合3A衛生型標準
• 高精度測量：采用符合IEC 60751 (或更高等級)的Pt100溫度傳感器

• 可滿足防爆區中的測量要求：
  - 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。根據實際應用工況，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基金會現場總線

• 可用于食品、制藥等衛生領域和精細化工行業的測量

• 溫度測量范圍: -50...250 °C

• 承壓能力可達 40 bar

• 防護等級可達 IP 68
