通信工程学院 毕业论文（设计）外文翻译 题目 单闭环温度控制系统 外文题目Single-chip temperature control system 专业：自动化 Single-chip temperature control system 1 temperature sensor The temperature sensor in the electric incubator control system is one of the very important components, will be responsible for the acquisition of the temperature of the incubator, that is, from time to time to acquisition the temperature of the incubator. It is to preach the collected temperature control section, and then the need for heating or stop heating a series of actions by the control section temperature sensor is a temperature probe of the electric incubator, so for the temperature sensors performance, including its The technical indicators of job stability, reliability and sensitivity must ensure that, because it directly affects the operation of the entire control system. The temperature is closely related to the physical quantity of a peoples living environment is also a need to control the important physical quantities in scientific experiments and production activities. Therefore, in a variety of sensors, the temperature sensor is the most widely used. The temperature sensor is a temperature change is converted to electrical changes in the device, used to detect the temperature and heat, also called thermoelectric sensor. Which temperature changes into the main components of the resistance change thermal resistance, thermistor and polymer NTC, PTC thermistor resistance, temperature thermocouple and the PN junction sensor for potential sensor, the thermal radiation conversion device for the electrical volume of pyroelectric detectors, infrared detectors, in addition to the integrated temperature sensor, fiber optic temperature sensors, liquid crystal temperature sensor, and intelligent temperature sensor, etc., more and more types of applications has become increasingly extensive. Temperature materials, the measured temperature into the temperature measurement system for measuring resistance, the mai
