摘要
文章介绍了大体积混凝土常用的3种温度传感器(铜电阻、铂电阻、热敏电阻)在实际兼测的缺陷,提出了改进的双斜坡积分、电解电容与电瓷电容合并使用、稳流源等技术在混凝土温度监测中保证测量精度的方法研究。从而有效地保证了大跨度电阻兼容测值的精度。
Disadvantages of three temperature sensors （copper resistor, platinum resistor and thermistor） widely applied in temperature measurement of mass concrete are described. The method study on securing precision of concrete temperature by technology of double slope integral, combination of electrolytic capacitor and ceramic capacitor, and constant current source, etc. is proposed. Accordingly,precision of temperature measurement by large - span resistance is secured effectively.
