温度是工业检测的重要物理量。温度传感器是利用材料、元件的温度特性测温的,要求材料只对温度敏感,且重复性好,滞后和时效小,灵敏度和精度高,性能稳定、可靠等。常用的有热电偶、热电阻及集成温度传感器。测量温度的方法和技巧热电偶测温范围广,下限达-270℃,上限达1800℃,热电阻常用的有铂电阻和铜电阻,铂热电阻测温范围为-200～960℃。铜热电阻常用来做-50～150℃范围内的工业用电阻温度计。LM35集成温度传感器测量范围为2～150℃。1.集成温度传感器 Temperature is an important physical quantity for industrial testing. Temperature sensor is the use of materials, components of the temperature characteristics of temperature measurement, the requirements of the material is only sensitive to temperature and good reproducibility, hysteresis and aging small, high sensitivity and accuracy, stable performance, reliability and so on. Commonly used thermocouple, RTD and integrated temperature sensor. Temperature measurement methods and techniques Thermocouple temperature measurement range, the lower limit of -270 ℃, up to 1800 ℃, the resistance of the resistance commonly used platinum resistance and copper resistance, platinum resistance temperature measurement range -200 ~ 960 ℃. Copper thermal resistance is commonly used to do -50 ~ 150 ℃ within the scope of industrial resistance thermometer. LM35 integrated temperature sensor measurement range of 2 ~ 150 ℃.
