Study on Sealing Thermal Characteristic of SRT Sensor
【摘要】 主要分析SRT传感器的传热过程,建立传热模型,从理论上分析其瞬态热响应特性,得出了理论的热响应曲线和热时间常数表达式,计算出塑封SRT传感器典型的热时间常数值。
【Abstract】 In this paper the process of thermas transfer of SRT Sensor is analyzed mainly and the thermal transfer model is established.The charccteristic of momentary thermal response is analyzed in theory,the expression of theoretidcal thermal response charcteristic curve and thermal time contrant are achieved and the typical thermal time constant of SRT sensor with plastic sealing is calcalafed.
