课程名称：工业过程控制的温度测量与校准 概述：本课程是针对过程工业中实际温度测量与校准的全面指南。它是“过程工厂操作与控制系统基础”课程的延续，旨在为工程学生、工厂技术人员和早期职业的仪器专业人员提供理论深度和实践 insight。课程开始时，我们将建立温度和热传递的科学原理，涵盖导热、对流、辐射以及热平衡的重要性。随后，您将探索常见的温度单位（摄氏度、华氏度、开尔文和兰氏度），并自信地学习如何进行单位转换。 之后，课程深入讲解热膨胀及各种温度计的工作原理，包括液体玻璃温度计、双金属温度计和压力弹簧类型温度计。您将学习不同材料的膨胀方式、工业温度计的构造以及如何为不同情况选择合适的仪器。 接下来，我们将讨论电气温度计，例如热电偶、RTD和热敏电阻。您将研究它们的内部构造、响应行为、测量电路以及如何应用冷端补偿以获取准确的读数。 最后，课程将探索非接触式温度测量，使用红外温度计和热成像仪。您将理解发射率、反射率和透过率等关键概念，以及它们如何影响红外测量结果。 到课程结束时，您将能够在实际工业环境中自信地选择、安装和校准温度测量设备。
This course is a comprehensive guide to practical temperature measurement and calibration for process industries. Designed as a continuation of "Fundamentals of Process Plant Operations and Control Systems," it offers both theoretical depth and hands-on insight for engineering students, plant technicians, and early-career instrumentation professionals.We begin by establishing the scientific principles of temperature and heat transfer, covering conduction, convection, radiation, and the importance of thermal equilibrium. From there, you'll explore common temperature scales (Celsius, Fahrenheit, Kelvin, and Rankine) and learn how to convert between them with confidence.Next, the course dives into thermal expansion and the working principles of various thermometers-including liquid-in-glass, bimetallic, and pressure-spring types. You'll learn how different materials expand, how industrial thermometers are constructed, and how to select the right instrument for different scenarios.We then move into electrical thermometers such as thermocouples, RTDs, and thermistors. You'll study their internal construction, response behavior, measurement circuits, and how to apply cold junction compensation for accurate readings.Finally, we explore non-contact temperature measurement using infrared thermometers and thermal imagers. You'll understand key concepts like emissivity, reflectivity, and transmissivity, and how they influence IR readings.By the end of the course, you'll be equipped to select, install, and calibrate temperature measurement devices confidently in real-world industrial settings.
