针对带电子温度控制的家用电器和其他仪器设备由于温度传感热敏电阻在传感时产生的灵敏度变化而导致控制电路产生误差进行分析和研究 ,得出产生误差有两种情形 :热敏电阻灵敏度下降和灵敏度增高。从热敏电阻的电阻温度特性和电压温度特性进行了深入的理论和实验分析 ,就不同灵敏度变化提出了两种不同的修正电路 ,并进行理论推理和实验测试证明其合理性 ,从而达到对热敏电阻转换灵敏度的修正目的
For household appliances and other equipment with electronic temperature control due to the sensitivity of the temperature sensing thermistor in the sensing caused by changes in the control circuit error analysis and research, the resulting error there are two cases: the thermistor Decreased sensitivity and increased sensitivity. From the thermistor temperature characteristics of resistance and temperature characteristics of the voltage in-depth theoretical and experimental analysis of different sensitivity changes made two different correction circuit, and theoretical reasoning and experimental testing to prove its rationality, so as to achieve the heat Sensitivity of sensitivity conversion sensitivity of the purpose
