In an engineering workshop an oven is used to heat small metal components to a temperature of 200 ˚C. The heater is powered by mains electricity and controlled by an on/off thermostat.
在工程车间中,使用烘箱将小型金属部件加热到 200 °C 的温度。加热器由主电源供电,并由开/关恒温器控制。
Discuss how the temperature in the oven could be measured. Write a maximum of 200 words. Use diagrams where appropriate.
讨论如何测量烘箱中的温度。 最多写 200 字。在适当的情况下使用图表。

The system is tested by switching the heater on and recording the temperature inside the oven at 10 second intervals. The thermostat is disconnected. Write a MATLAB program to load the temperature data (from the file ovenTEMP.txt) and plot a graph. Comment on the graph.
通过打开加热器并每隔 10 秒记录一次烘箱内的温度来测试系统。 恒温器已断开连接。 编写一个 MATLAB 程序来加载温度数据(来自文件 ovenTEMP.txt)并绘制图形。在图表上添加注释。
