摘　　要：针对工业环境温度测量要求,设计了基于四线Pt100的温度检测系统。首先采用Pt100热电阻对环境温度进行采集,然后通过Jumo温度变送器把mv信号转换成4~20mA标准信号,再用西门子SIPART DR20单回路调节器调节和显示温度。通过实验和数据分析证明,该温度检测系统具有易控制、工作可靠、测距准确度高、可读性强和流程清晰等优点,可以进行建筑及工业领域需要进行温度检测及调节的场合。Aimed at reach the measurement requirements of industrial environment temperature,a temperature detection system was proposed based on four-line Pt100 resistance. Firstly, using Pt100 resistance to acquire the environment temperature, and then converts the mv signal to4~20mA standard signal by Jumo temperature transmitter. Lastly, use Siemens SIPART DR20 single loop controller to adjust and display the temperature.The experiment and its data analysis show that the temperature detection system has advantages such as easy to control, reliable to operation, has high ranging accuracy, readable and has clear flow, which not only can measure the indoor temperature, but also fit to the industry that needs to detect and regulate temperature.
