摘要
提出了一种适用于铂电阻型温度传感器信号调理电路。该电路测量精度可达0.05%,可在较恶劣的环境中保持高精度工作。同时该电路结构简单,可通过简单更改桥臂电阻及放大系数配置电阻实现PT100及PT1000型传感器的兼容。
This paper presented a signal conditioning circuit for platinum resistance type temperature sensors.The circuit has a measurement accuracy of 0.05%and maintains high precision operation in harsh environments.At the same time,the circuit has a simple structure,and the compatibility of the PT100 and PT1000 sensors can be realized by simply changing the bridge arm resistance and the amplification factor configuration resistor.
