一体化RTD热电阻，卫生型结构设计
具有多种过程连接形式和延长颈类型
高灵活性：模块化结构设计、标准接线端子块和用户自定义热电阻插入深度
提供绝大多数常见的EHEDG认证卫生型过程连接，仪表的结构设计符合3A卫生型标准
测量：采用符合IEC 60751 (A级或高等级)的Pt100温度传感器
可满足防爆区中的测量要求：
- 本安型仪表(Ex ia)
- 无火花 (Ex nA)
一体化温度变送器
相比于不经过温度变送器，而直接接线的测量方式，Endress+Hauser的一体式温度变送器具有高的测量精度和高的测量可靠性。根据实际应用工况，用户可以自由选择下列信号输出模式和通信方式：
4...20 mA模拟输出
HART®
PROFIBUS® PA
FF基金会现场总线
可用于食品、制药等卫生领域和精细化工行业的测量
温度测量范围: -50...250 °C
承压能力可达 40 bar
防护等级可达 IP 68
