NTC负温度系数热敏电阻历史

NTC热敏电阻器的发展经历了漫长的阶段1834年，科学家首次发现了硫化银有负温度系数的特性1930年，科学家发现氧化亚铜-氧化铜也具有负温度系数的性能，并将之成功地运用在航空仪器的温度补偿电路中随后，由于晶体管技术的不断发展，热敏电阻器的研究取得重大进展1960年研制出了NTC热敏电阻器

NTC负温度系数热敏电阻温度范围

它的测量范围一般为-10℃～+300℃，也可做到-200℃～+10℃，甚至可用于+300℃～+1200℃环境中作测温用

负温度系数热敏电阻器温度计的精度可以达到01℃，感温时间可少至10s以下它不仅适用于粮仓测温仪，同时也可应用于食品储存、医药卫生、科学种田、海洋、深井、高空、冰川等方面的温度测量
