摘要
介绍了一种利用线性放大器、模拟乘法器、加法器及电压 /电流转换器实现线性化处理的热电偶温度变送器 ,给出了线性处理方法及相关的电路设计原理。理论和实验证明 ,其非线性误差可控制在 0 .2 %以下。
The paper introduces a thermocouple temperature transmitter which uses linear amplifier, analog multiplier, adder and voltage/current converter to achieve linear treatment. The linear treatment method and the relative circuit design theory are given .Theroy and experiment show that nonlinear error can be controlled under 0.2% with this method.
