摘要/Abstract

摘要： 铜电阻与热敏电阻温度计常用于岩土工程混凝土温度监测，为进一步了解两种仪器应用情况，从仪器结构、测量、绝缘度影响等方面，结合工程实例分析，认为铜电阻温度计在生产管理、电缆芯线电阻、绝缘电阻影响等方面要优于热敏电阻温度计，铜电阻温度计更能适合水工环境，具有较好的长期稳定性。热敏电阻温度计采用四芯电缆加长，测出电缆芯线电阻，可消除长电缆给温度测量带来的影响，相关成果可供工程管理、工程设计、科研人员等参考。

Abstract: Both copper resistance thermometer and thermistor thermometer are commonly used in geotechnical project to monitor the concrete temperature. To understand the application of the two instruments, comparison is carried out, including the aspects such as instrument structure, measurement and insulation. Combined with engineering cases, it is considered that copper resistance thermometer is superior to thermistor thermometer as far as production management, cable core resistance and insulation resistance. As well, the copper resistance thermometer is more suitable for hydraulic environment and it has better long-term stability. The thermistor thermometer is lengthened with 4 core cable. Measurement of the resistance of cable core can eliminate the influence of long cable to temperature measurement.

Key words: concrete temperature, copper resistance, thermistor, thermometer, comparison
