The development and application of a new logging thermometer

针对现有井温仪存在的设计复杂度较高、采用模拟信号传输易受电磁干扰等问题,作者提出了一种新型井温仪的设计方案。采用数字输出型IC温度传感器+双处理器+双电源+数字通信,以期实现设计简单、数字传输、抗干扰能力强、传输距离远、使用方便等优点,介绍了具体的实现方法和工程应用。在某水库大坝开展渗漏分析与处理工作中使用新型井温仪进行井温测量,结果表明新型井温仪具有较高测量精度和分辨率,可广泛用于各种水体的直接水温测量,尤其是深孔井温测量。

Aiming at some problems in the current logging thermometers,such as high design complexity,susceptibility to electromagnetic interference when using analog signal transmission and so on,the authors proposed a new design scheme of logging thermometer,which adopts digital IC temperature sensor,dual processors,dual power supply and digital communication to realize the advantages of simple design,digital transmission,strong anti-interference ability,long transmission distance,easy to use,etc.The specific implementation method and application in engineering are also introduced.In the leakage analysis and treatment work of a reservoir dam,a new type of well thermometer was used for well temperature measurement.The results showed that this new well thermometer has high measurement accuracy and resolution,and can be widely used for direct water temperature measurement of various water bodies,especially for deep hole well temperature measurement.
