5年质保

对于在高电压电位环境中使用 Pt100
电阻温度计测温的任务，常规温度测
量变送器通常会由于绝缘强度不足而
无法胜任。
虽然电阻温度计可以采取绝缘措施，
具备高压耐受能力，但这通常需要在
安装空间方面做出让步；这样一来，几
乎无法实现符合标准的绝缘。此外，热
老化和机械老化也会削弱绝缘能力。
在电力电子组件上测量温度，尤其是
测量和/或控制电机、发电机或变压器
的绕组温度时，与 Pt100 电阻温度计
之间耐受高压的电气隔离装置可以确
保超高安全性。

解决方案：
基本绝缘达 6.6 kV AC/DC 的
Pt100 测量变送器
适用于高压应用的新型 Pt100 测量
变送器 P44000，将 2、3、4
线制 Pt100 电阻温度计的电阻值高
精度、低延迟地转换成 4 ~ 20 mA 信
号。
输出信号与输入信号和电源之间进
行电气隔离。电气隔离措施设计用于
6.6 kV AC/DC 及以下工作电压。进行
器件测试时，使用 15 kV AC 的测试电
压。真空封装既保护电路免受环境影
响，又为长久保持出色的绝缘性能提
供有力保障。
产品系列覆盖测量范围 0 ~ 150°C、
0 ~ 200°C 和 0 ~ 300°C 的常见应
用领域。提供模块化外壳宽度为
67.5 mm 和 22.5 mm 的设备，满足
不同需求。
