摘要
设计出了一种高低温温度控制样品室,温度控制范围-100～200℃,采用二极管和铂电阻作为温度测量传感器件,利用二极管的PN结温度特性对液氮液面进行标定,利用铂电阻对样品室温度进行测量和控制.
A kind of high and low temperature control between -100 ~C and -200 ~C. It adopts diode and sample cell is designed. The temperature is platinum resistance as temperature measure uses diode＇s PN joint temperature characteristic to demarcate the liquid nitrogen level and makes platinum resitance to measure and control the sample cell＇s temperature. controlled sensor. It use of the
