一、前言近年来,随着微处理机技术迅速发展及在各个领域中得到广泛应用,各种仪器、设备的电子化控制(机、电、仪一体化)也正在蓬勃发展。而巳电子化控制对高性能、高可靠性、低成本传感器的要求十分迫切。据国外最近统计,在各种传感器中,人们对温度传感器的关心程度仅仅次于光电传感器,名列第二。温度传感器是感知和检测温度这一物理量的器件,如大家所熟悉的:有热电偶、热电阻(如铂电阻、铜电阻等温度计)以
I. Introduction In recent years, with the rapid development of microprocessor technology and its wide application in various fields, the electronic control (integration of machinery, electricity and instruments) of various instruments and equipments is also booming. The electronic control of high performance, high reliability, low-cost sensor is very urgent. According to recent statistics abroad, in a variety of sensors, people are only concerned about the temperature sensor photoelectric sensor, ranked second. Temperature sensor is a device that senses and detects the physical quantity of temperature, as we all know: There are thermocouples, thermal resistance (such as platinum resistance, copper resistance thermometer) to
